Standard vs. Quiet Sump Pump Check Valve

It’s difficult to perceive the difference between a Standard Check Valve and a Quiet Check Valve, but it’s easy to grasp the distinction because it’s in the name. A Standard Check Valve is placed if you hear a loud noise whenever the pump stops. This noise is the check valve closing, which causes a slamming sensation as the water reverses direction in the discharge pipe after the pump stops. If you have never noticed it, you probably have a Quiet Check Valve.

Let’s take it a step further and compare the advantages of installing a Standard Check Valve with a Quiet Check Valve, which will make it easier for you to determine what is ideal for your home.

What is a standard check valve for a sump pump?

A Standard Check Valve safeguards your sump and sewage pump installations against backflow. The angled seat reduces the distance the flapper must travel from the open to closed position. When closing, significantly reduce the force with which the flapper touches the seat. The tilted seat design reduces the flapper’s travel distance, hence reducing flow reversal, noise, and possibly damaging hydraulic shock (water hammer). This, combined with corrosion-resistant non-metallic components, produces a durable and dependable valve.

The graphic below depicts the closing action of gravity. Clearly, there will be a flow reversal when the pump stops, until the poppet reaches its fully closed position.

Definition of a Quiet Sump Pump Verify Valves?

When ultra-quiet operation is necessary, a Quiet Check Valve is an excellent option. Quiet Check Valves are identical to ordinary check valves, with the addition of a spring-loaded hinged flapper mechanism that compels the flapper to fully close against fluid flow when the pump is turned off. This quick closing motion against pressure eliminates noise caused by hydraulic shock before flow reversal may occur (water hammer).

The spring-assisted closing action prevents flow reversal when the pump is turned off. The poppet moves to its fully closed position before to the complete cessation of water flow.

It boils down to individual preference

The Standard Check Valve vibrates when the pump cycles and is resistant to corrosion. Providing a longer-lasting check valve and the assurance that you can hear your sump pump operating.

The Quiet Check Valve’s spring-loaded flapper design removes noise, resulting in a silent sump pump. Providing a peaceful environment throughout the day, morning and night.

Why Do Sump Pump Float Switches Fail?

Why Do Sump Pump Float Switches Fail?

 

The main mechanical cause of the problems of the deposit of the pump is the exchange problem. Here are some common causes of tank pump float switch failure:

Float Change Frequently, the float falls into the trap between the pump and the reservoir wall and is unable to rise sufficiently to be effective. Due to the pump’s modest vibration during operation, it is able to “pass” through the well’s bottom, assuring buoyancy between it and the well wall.

Sometimes, after so many lifting and lowering cycles, the float switch simply gives up and ceases to respond to the rise and fall of the well’s water level. It frequently stops when the pump is operating. When this occurs, the pump stays on until the fuel burns.

Power outage due to inclement weather is a formula for a flooded basement. The entire tank’s float switch and pump are electrically powered. When the unit is turned off, the pump stops draining water altogether.

Why Is A Float Switch Valuable?

The float switch on a sump pump is the mechanism responsible for turning on and off the sump pump system. It functions using a small, floatable attachment that rises and falls with the sump pit’s water level.

As the water level in the sump pit rises, the float switch is raised. As it reaches a specific height, the mechanism is activated. The sump pump switches off once again as the water level in the sump pit decreases.

When this float switch fails to rise or becomes locked in the “on” state, the problem develops. At certain situations, the sump pump will either fail to turn on or be unable to turn off, eventually causing the motor to overheat and die. Regardless, you can anticipate a basement flood during the next rainfall.

Choosing The Right Sump Pump

Sump Pump Float Work

Pumps vary widely in quality. Pumps are used in a variety of applications, such as chemical vats, fuel depots, and swimming pools, but each one may present a different set of difficulties. The U.S. Department of Energy suggests the following factors to think about when choosing a pump:

Fluid: Pumps that weren’t designed for the job can be destroyed by chemicals and fuels. Select a pump that is made to handle the fluid’s corrosiveness and consistency to prevent degradation or clogging from slurry or debris. Similar to this, be aware of the fluid’s viscosity to make sure the pump has sufficient force to draw the liquid through.

Calculate the desired flow rate by dividing the total volume by the desired transit time for the liquid. For instance, if a 500-gallon pond requires full circulation once every hour, you should choose a pump with a 500 GPH minimum rated flow rate (gallon per hour).

Although pumps can function in a wide range of temperatures, if you are working with liquids that are hotter than 200°F, make sure the pump is rated for the highest liquid temperature you will be pumping.

Vapor pressure: The force per unit area that a fluid exerts when changing from a liquid to a vapor is known as vapor pressure, and it can be used to reduce the risk of cavitation by making sure the pump is rated for it.

Choosing a Pump from a Variety of Types

You can start comparing your options for pumps once you know the materials they must handle and the capabilities they need. The most typical pump designs and operating principles available today are listed below:

Centrifugal pumps: A centrifugal pump draws fluid into one or more impellers, such as a paddle wheel or propeller, to maintain a steady flow of a large volume of fluid at high speed. It can be used to pump a variety of low viscosity liquids, including those containing solid components like wastewater, and is one of the most popular pumping systems. A wide range of industries, including agriculture, water utilities, industry, power generation, petroleum, mining, and more, use centrifugal pumps.

Diaphragm pumps: Also called membrane pumps, a diaphragm pump is a device that moves fluid by a series of diaphragms moving back and forth. In a cycle, fluid is forced out of one chamber as it enters the other. These pumps are useful for pumping liquids with high solid content or high viscosity, such as chemicals, paints, or syrups, because there are no moving parts within the diaphragm chambers themselves.

Pumps that circulate fluids within a system are used instead of pumps that move liquid from one location to another. In order to ensure that the hot water is evenly distributed with the incoming cold water and to maintain a constant temperature, circulating pumps are frequently used in water heating systems. A circulating pump can also be used to evenly distribute chemicals that have been mixed into a container or to move water around a pond to oxygenate the water.

Pumps for moving oil, fuel, and other materials from one container to another, such as transferring fuel from a tank into large machinery, are known as fuel and oil transfer pumps. Oil transfer pumps are made for use with high viscosity fluids and are toughly constructed for higher flow rates.

Pumps for chemicals: Chemical pumps are made specifically for the creation, use, and disposal of chemicals. They are constructed of corrosion-resistant materials like glass, rubber, plastic, rubberized steel, titanium, and stainless steel. Use a pump made specifically for the chemical you want to pump because different chemicals have different corrosive effects on materials.

Drum pumps: These pumps are designed to help you suction out fluids from drums, barrels, pails, and totes to reduce the risk of spills when pouring the container or to draw fluids out of a heavy container. Hand-powered pumps are useful for low-volume or remote pumping applications where electricity is not available, whereas electric-powered pumps are useful for tasks requiring high volume transfer. A pneumatic pump that runs on compressed air is a good choice if you need higher flow rates than a hand-powered pump and more precise flow control than an electric drum pump without electricity.

Sump pumps are set off automatically once the water level in the sump pit gets to a predetermined height. A homeowner can calibrate the pump to start at any depth they wish by adjusting the float device of the sump pump.

Water runoff and/ or seeping water is collected inside the sum pit. As the water gathers, a float rises as the water level rises. The float has control of an on/ off switch for the pump. Once the float rises to a predetermined height, the pump turns on. The pump continues to function until the float falls low enough to disconnect the switch. The pump is inactive once more until the water level increases again.

Types of Sump Pump Floats

Different types of floats are used by different types of sump pumps. Pedestal pumps will typically have a bulb type float connected to a metal rod that turns on the pump motor’s switch. Other types of pumps utilize floats attached to arms that will raise and lower as the water level rises and lowers. A tethered float is a float that is attached to the pump utilizing a tethering mechanism.

Old Sump Pump Float Working Principle

When the water level rises, the float will rise too. As the float rises the tether steadily releases. The tether is predetermined to start the pump when a specific amount of tether gets released. When the water levels lower, the tether becomes loose and the float falls back to its starting position.

New Sump Pump Float Working Principle

Float switches and water level controls typically start out open, meaning there are no alarms that are required to be activated since the water level is at its lowest.

  1. When the cooling tower stops using the water for its industrial operations, the water level starts to rise. No alarms have been activated up to this point.
  2. When the water level reaches the probes, a signal is transferred between the probes informing the high alarm to activate.
  3. When the high alarm is activated it can be programmed to tell the fill to stop filling up the water.
  4. Finally, when the water reached the predetermined limit, the fill stop kicks in and the process starts all over again.

With correct maintenance, your cooling tower float switches could last for years of operating. A lot of float switch failures typically occur due to degrading, wearing out, or fouling. Cooling tower coatings can safeguard the storage tanks, but what is safeguarding the float switches? Our water level controls can replace your old float switches once and for all and won’t degrade, wear out, or foul, because of any water quality.

Water Management in Intelligent Buildings and IoT

Intelligent buildings are the culmination of technological advancements that enable cost containment, efficiency, sustainability, and occupant satisfaction through system optimization. While solutions for intelligent buildings have traditionally been positioned to promote energy efficiency, as the market matures, vendors are emphasizing broader benefits. One such benefit is the conservation and management of water, which is becoming an increasingly important issue in commercial buildings. Advocates have long struggled to increase widespread investment in water-saving technologies and the adoption of intelligent building solutions.

Sensor technology and Internet of Things (IoT) devices are becoming more prevalent in commercial building management. This intelligent building management technology provides building owners and occupants with real-time data that can be used to drive or automate decisions, resulting in cost savings and resource conservation.

For example, the growing trend of remote, telecommuting office workers can be addressed through occupancy sensors that detect the presence or absence of employees in work areas, ensuring that the building is lit, cooled, or heated only when necessary. According to a recent study, smart technologies can help the average office building save 18% of its energy consumption. 1

Several of these systems can also take into account tenant or office worker feedback. Comfy, a smart workplace phone or computer app, collects user preferences for workplace temperature settings, aggregates the data, and then instructs the building’s smart energy system to adjust temperatures automatically to maintain a comfortable working environment.

Why is Smart Water Management Gaining Traction?

While the primary focus of IoT devices in smart building management has been on energy savings, their ability to save water is gaining traction. Ecova found that 57% of energy, facility, finance, and sustainability managers had invested in water conservation measures in 2016. Water conservation efforts, such as irrigation controls and behavioral change, were viewed as low- or no-cost priorities by the surveyed group. 2

Today’s investments in smart water management are simple to implement and quickly pay for themselves.

By 2025, the water management technology market is expected to reach $2.8 billion.

Following irrigation, the next step is to integrate smart water technologies into facility management, which is the direction in which the industry is headed, according to a Navigant Research report.

Trends in Intelligent Water Management

Global investment in water management technologies and services is expected to double to $2.8 billion by 2025, the report states, as water management becomes a standard component of smart buildings. As corporate sustainability and energy efficiency become more important, vendors of smart building technology are demonstrating more comprehensive tools, including some designed specifically for water conservation and management.

Significant corporations are under increased pressure from shareholders and customers to demonstrate sustainability action. Customers are seizing the opportunity to manage their water consumption through targeted actions that make economic sense, as the bottom line remains the primary driver of business investment today. Three emerging technology areas are water-efficient plumbing, irrigation management, and monitoring software.

Manage Facility Water Use Effectively Using Smart Water Management Technology

Smart water management technology provides the data and tools necessary to manage water use more effectively. The data collected by smart water devices is integrated with building management systems to demonstrate how much water is being used and to identify areas where water can be used more efficiently.

Here are some ways that HydroPoint’s smart water management tools can assist you in reducing water waste:

Integrated dashboards that display real-time water use data assist you in adhering to water restrictions or budgets for outdoor irrigation.

Water leaks, large and small, indoors and outdoors, can be detected and reported 24 hours a day with 24-hour water usage monitoring and reporting. Alerts can be sent to a computer or a mobile device in the event of a leak.

Automated irrigation schedules based on weather or soil moisture data promote plant health and prevent overwatering landscapes, resulting in decreased plant loss, hardscape damage, common area hazards, and stormwater runoff.

Controlling the system remotely via computer or mobile device eliminates the need for site visits and wet checks.

Sustainability, as well as corporate commitment to intelligent buildings, are significant drivers for early movers in the water management market. However, a lack of regulation and a disparity between the true cost of water and its price are two impediments to water conservation and management. Investment in three segments of water management—software and services, water-efficient plumbing, and irrigation management—provides economic and environmental benefits, but adoption rates and scale vary significantly by region and customer sector. Global investment in water management solutions is expected to increase from $2,007.9 million in 2016 to $2,862.3 million in 2025, according to Navigant Research.

This Navigant Research report examines the opportunities and challenges associated with deploying water management technologies and services in intelligent buildings. The study investigates the major market dynamics influencing water management solution adoption at the macro level, as well as by customer sector (building type) and region. Revenue forecasts for the global market are provided through 2025, segmented by customer sector, technology segment, and region. Additionally, the report examines key water management technologies for intelligent buildings, as well as the competitive landscape.

Significant Issues Addressed:

  • What is motivating interest in intelligent building water management?
  • Which of the following are the primary impediments to investing in intelligent building water management?
  • What are the advantages of intelligent building water management?
  • Which customer segments stand to gain the most from intelligent building water management?

Fire Safety in Smart Buildings

We’re seeing all aspects of our lives become smarter as technology advances. From our phones to our homes and now to commercial buildings, we are surrounded by technology. We are not only designing buildings that improve efficiencies, but also buildings that make our lives easier. Consider a structure that understands your heating and lighting preferences based on the time of day. Depending on the number of people in the building, a smart building will turn them off or on.

What are smart buildings and how do they work?

Smart buildings contain integrated technology systems that control and automate IoT (Internet of Things) applications, procedures, and processes, as well as collect data to improve internal operations. Smart buildings provide a level of connectivity through their intelligent networks, which are powered by advanced software and interfaces to provide control over a variety of aspects, including heating, lighting, room scheduling, energy consumption, air ventilation, and fire safety and security.

By integrating these systems into their smart building’s network, smart buildings have revolutionized the capabilities and control a business has over its fire safety and security. Integrating fire safety and security into smart buildings can have enormous benefits for employees, the building, and the overall business, from data analysis to automation.

What are the Advantages of Smart Structures?

Smart buildings have a number of advantages that benefit both the company and its employees.

Get Access to Smart Data

Smart technology allows you to receive smart data that will provide you with a detailed understanding of how IoT systems work and how efficient your processes are. Do you want to know who is in your building and where they are? What are the statistics on security system triggers, as well as your overall energy consumption? All of this data can be collected and presented in one unified space by a smart building.

Efficient Energy Consumption

A smart building provides the data necessary for optimal efficiencies, which means that all integrated systems can be controlled to reduce unnecessary energy consumption and thus improve the building’s overall environmental impact.

Access control and motion sensors, for example, can detect whether or not someone is present in a room. If they aren’t, lights and heating/air conditioning can be turned off automatically. Furthermore, appliances that are not in use can be programmed to turn off automatically.

Detection of Faults Automatically

Smart buildings have the advantage of constant data, allowing for real-time monitoring of all systems. The ability to monitor and identify system faults is extremely beneficial to a company because the fault can then be automatically sent to the monitoring provider or building management team. This not only makes the workplace safer for employees, but it also eliminates the need for someone to notice and report a problem.

Find out how the building is used

The ability to learn how the space is used is a key benefit of smart buildings that is often overlooked. Motion sensors, access control, and CCTV are excellent tools for determining which areas are at risk in the event of a fire, a security breach, or even which meeting rooms and desks are available for use.

Increased Productivity

The most well-known benefit of smart buildings is their ability to increase efficiencies, not only in the individual systems but also among employees. Because of the controlled environmental impacts, such as the level of air ventilation and the automation of certain tasks, employees will be able to work more productively.

Cost-cutting

Smart buildings also have the financial benefit of lowering overall costs. This is primarily due to increased overall efficiencies achieved through data analysis and automation, which aid in the elimination of inefficient energy use, employee productivity, and building space utilization.

How Can a Smart Building Integrate Fire Safety?

With the use of wireless, cloud-based, and app-based systems, improved fire safety can be easily integrated into a smart building. When temperature sensors determine whether a piece of equipment is overheating and smoke alarms automatically activate an emergency response, a smart building can significantly improve fire safety.

We can integrate fire alarms, emergency lighting, fire extinguishers, and fire suppression systems into a smart building that can be controlled from a central control point and work alongside existing systems like CCTV, motion sensors, and heating. A smart building will not only be able to detect a fire, but it will also be able to take the necessary steps to prevent one from occurring in the first place.

How can a smart building’s security be integrated?

Security, like fire safety, is easily integrated into a smart building and is critical to keeping a building and its occupants safe.

Motion sensors and intruder alarm systems, for example, can be combined to detect an intruder in a specific area of the building. After that, access control can be used to prevent the intruder from moving around the building until the authorities arrive.

Altitude Valve: What is it and How Does it Work?
Written by webtechs

Altitude Valve: What is it and How Does it Work?

An Altitude Valve is a mechanically operated control that relies on a differential of pressure between inlet and outlet to assume a level of water, and control its flow when the supply pressure becomes much higher than the head developed by the full reservoir or storage tank. Frequently used in supplying water in high-rise buildings, ground storage tanks or reservoirs, they have also traditionally been used in remote areas where modern equipment used to be at a disadvantage due to lack of electricity. Today, with cheap reliable batteries and solar power readily available, an upgrade to modern equipment with proper monitoring and alarm systems is within easy reach. Instead of using an Altitude Valve, use a Paragon Valve with a Waterline Controls Fire Protection unit.

Freezing Temperatures

In many climates low temperatures can be an issue when a mechanical valve is used. While in the past a layer of ice on the water surface could render a float valve inoperative and make a remote altitude type valve seem a good choice, today an electronic sensor can include temperature monitoring and reporting/alarm status when the potential for freezing arises.

Costs

Even smaller water suppliers who used to be concerned with costs of upgrading find that between the lower costs of electronic controls, the lack of maintenance issues or failures, along with remote activity reporting and monitoring, modern electronic sensor level control systems are helping relegate altitude valves to situations where conservation, reliability and supervision are not required.

Complications

Obviously, directly measuring the level of water with a sensor is many times more accurate than a pressure differential assessment. Consideration must also be given to the inlet pressure, to ensure it is always greater than the water level head pressure. Too low a pressure will cause the system to equalize the inlet and outlet pressure, and without a differential pressure, the valve will be stuck, trying to fill but never reaching the max level. With no differential pressure the system fails, with no water flowing in or out of the tank.

Options

Waterline Controls™ Liquid Level Controls Systems can operate from Solar powered panels that produce 30vdc, or a battery system charged via solar panel. All systems can connect to a Fire Panel or building management system for full monitoring and fault reporting, with alarms. Without the maintenance and costs of altitude type controls, with advanced monitoring and reporting, full automation compatibility and extreme reliability, there is no reason not to upgrade to modern reliable systems that take into account our responsibility to properly manage and conserve our limited and important water supply.

 

Standard vs. Quiet Sump Pump Check Valve

What Is A Lift Station?

A house or company owner does not consider lift stations unless something goes wrong. When the gradient of the terrain prevents natural flow, a lift station is utilized to pump wastewater or sewage from a low level to a higher level.

The wet well and the controls are the two primary components of a lift station. The inflow is emptied into the wet well, which is also where the pumps are located. The lift station’s control panel is its brain.

So, how exactly do lift stations function? A pit is used to hold and feed sewage. When the sewage level in the pit reaches a specific level, electrical instruments detect that the pit is full and activate the pump, which pumps the sewage to its next destination. Because sewage can generate harmful gases like methane and hydrogen sulfide, most lift stations are located underground to avoid health dangers in tight spaces. As a result, owners of existing lift stations should consult a specialist to confirm that the pump is still functioning properly.

A expert can also guarantee that your lift station is properly maintained. Lift stations require maintenance to avoid the need for costly repairs because the pumps, electronic controllers, and electrical system are all in a constantly corrosive environment.

Wet wells must be pumped out and cleaned to prevent solids and grease buildup, pumps must be inspected, check valves must be greased, and floats must be inspected and cleaned to ensure optimal functioning. An inspection of all electrical motor-control equipment, as well as the basin, clean-outs, and coverings to avoid buildup, is also covered.

What constitutes a lift station’s components?

A lift station is made up of a number of critical mechanical components that must be monitored for efficiency, repair, and failure.

A lift station’s main components are:

  • a receiving well for sewage
  • Pumps, pipes, and valves for submersible pumps
  • motors
  • a power distribution system
  • a system for monitoring and controlling equipment
  • a system for odor control

Lift Stations Come in a Variety of Shapes and Sizes

Lift stations are often used by municipalities in charge of collecting and processing wastewater. The dry well/wet well pump, which is more conventional, and the submersible pump, which is more modern.

Well, it’s dry.

The system is housed in a separate place in dry-well lift stations (usually underground or in a separate chamber). Maintenance on a dry well is more risky and poses additional safety hazards due to this physical isolation.

Pump that can be submerged (Wet Well)

Submersible pumps are submerged in the wastewater they pump, as the name implies. It is installed within the wet well and pumps the wastewater with a motor. This method is more modern because it has less health and safety risks.

Chillers In Winter Weather Conditions
Written by webtechs

Chillers In Winter Weather Conditions

Chillers have to be able to work year round and in some cases it is a good idea to make sure your chiller can work at maximum capacity. Follow these tips to make sure your chillers work hard through the cold weather.

 

  • Glycol charts will display the ambient temperature and give you an indication of the total amount of glycol you will need. To do this you will have to utilize a refractometer, specifically inhibited propylene glycol that is especially made for HVAC systems, especially for high and medium temperature chiller applications.
  • Snow and ice must be kept off the chiller condenser coils as they can damage fan blades and restrict the air flow through the condenser and this will reduce the potential of the cooling abilities of the chiller.
  • Use the manual controls for your head pressures. Head pressures drop during very cold weather and if the chiller is not one that has ambient control equipment such as a flooded condenser or fan cycling, the chiller may not operate correctly. One way of solving this is to block the flow of air through the condenser by wrapping it with plastic or using some card board to block the condenser. it is not a perfect fix, nor a permanent one but will work on a temporary basis.
  • By allowing the pump to run, it should provide sufficent warm water to keep the fluid above the freezing level or above the freeeze levels of the glycol. But at night, the ambient temperature of the air will cool down the fluid rapidly. When the pump is allowed to run, heat will be added from the pumps and from inside the buildings.
  • By planning ahead, you can ensure your chiller is equipped to handle the cold weather conditions in your environment. If you perform a maintenance check in Spetember, it will give you ample time to make any needed alternations.
  • Make sure everything in the system is correctly and completely installed including pumps, piping, safeties and controls.
  • Make sure the cooler evaporator is connected to its separate electrical service and checked for the correct voltage.
  • Perform an inspection for cracks and leaks before the onset of cold weather. This may be an action that saves you tens of thousands of dollars over the winter.
  • Develop a back up plan should your chiller lose power over the cold weather period of the year.

Types of Pumping Stations

A pump station is a product used to lift or move water when no gravity fall can be achieved. Installed underground and often cylindrical in shape, the pump station would normally have 1 or 2 pumps installed inside it. Float switches monitor the level of water in the tank. As water enters the tank and fills up, the float switch activates the pump to move the water to its desired location.

 

Different types of pump station

There are different types of pump stations depending on the application and water it is receiving as follows:

 

Crude pump stations

A crude pump station (or sometimes called a raw sewage pump station) is designed to move wastewater from a building. The pumps will normally be vortex pumps with a large free passage to enable solids to be moved, or grinder pumps which churn up solids to allow pumping through narrower pipes.

 

Final effluent pump stations

A final effluent pump station is designed to be used to move treated water (containing no solids). These are commonly used when the outlet of a treatment plant needs to be lifted. The pump station can be fitted with single or twin pumps. Alarm options are also available.

 

Surface water pump stations

A surface water pump station works in the same principle as all pump stations, it takes water from surfaces (roofs, or groundwater) and used in the event no gravity fall can be achieved. The pump(s) will be sized depending on the estimated flow rate and the distance the pump has to move the water.

 

Adoptable vs Private Pumping Stations 

Broadly speaking, pumping stations can be divided into two main categories – Adoptable Pumping Stations and Package Pumping Stations.

 

Adoptable Pumping Stations are designed for large-scale applications and comply with all Water Company requirements, Sewers for Adoption specifications and the DCG (Design Construction Guide), making them suitable for use on public land.

 

Package or Private Pumping Stations are used for removing wastewater from privately run developments, whether residential or commercial properties.

 

Sometimes ownership of pumping stations is transferred, via a legal process known as pumping station adoption. For example, legal ownership in a housing development might be transferred from the developer to the local water authority. They would then be responsible for the ongoing maintenance of the pumping station.
