What Is a Break Tank in a Fire Protection System?

A break tank is a water storage tank that is used in fire protection systems to make sure that fire pumps always have a steady flow of water. Municipal water pressure is not powerful enough or steady enough to meet fire protection needs in many commercial and industrial structures. A break tank fixes this by holding a set amount of water that can be pulled right away and at full flow in case of a fire.

Break tanks are like a buffer between the building’s fire pump and the municipal or onsite water source. They make sure that the system always has access to the water it needs, no matter what happens with the pressure, lines, or supplies.

The Purpose of Break Tanks in Fire Protection

1. The pressure of municipal water isn’t always high enough.

Fire pumps need a certain amount of pressure and volume to work properly. Many communities can’t keep up with the steady flow that is needed, especially during busy times. A break tank makes sure that the fire pump always has a steady supply.

2. They keep pumps safe and stop backflow.

The break tank keeps the fire system and the municipal line apart. This keeps city water from being dirty and stops pump pressure from forcing water back into the supply line.

3. They make sure that fire codes are followed.

NFPA 22 and NFPA 20 have tight rules for the water that is kept, how well fire pumps work, and how reliable the system is. Break tanks assist structures achieve these regulations, especially when the city’s water supply isn’t always stable.

How a Break Tank Works

A break tank is usually put in at ground level and filled up automatically with float valves or, better yet, electronic water level controls for more accuracy and dependability.

This is how the system works:

  • The tank holds a specific amount of water that the fire pump needs to work.
  • Electronic water level sensors keep an eye on the tank all the time and make sure it is filled to the right level.
  • When the fire pump turns on, it doesn’t get water from the city line; it gets it straight from the tank.
  • The control system starts refill mechanisms when the water level drops, but it stops overfilling, dry running, or pump damage.

WaterLine Controls and other companies who make electrical water level controls make sure that the tank always has the right amount of water for safe operation. Electronic systems are better for important fire protection uses since they don’t get damaged by debris, scale, or corrosion like mechanical floats do.

Final Thoughts

A break tank is an important part of many fire prevention systems because it makes sure that fire pumps always have a reliable, code-compliant water supply. When used with accurate, maintenance-free electronic water level controls, it gives commercial buildings, institutions, and industrial facilities the safety and dependability they need.

What Is an Electrical Water Level Sensor?

An electrical water level sensor is a device that can find, measure, and keep track of the height of water in a tank, reservoir, pit, basin, or other holding system. These sensors are very important for keeping water levels stable, preventing overflow, and protecting pumps and equipment from damage in commercial buildings, industrial facilities, wastewater systems, and homes.

Modern electrical water level sensors let you monitor and control the water level automatically, so you don’t have to estimate or check it by hand like you do with older mechanical float systems. Because of this, they are more reliable, accurate, and long-lasting.

How an Electrical Water Level Sensor Works

Most electrical water level sensors work with one of a few basic technologies, however the designs might be different depending on the use:

1. Probes

These have probes or rods made of stainless steel that go into the tank. When water hits a probe, it makes an electrical circuit. Each probe is linked to a certain water level (low, fill, high, etc.), which lets the system turn on pumps or alarms on its own.

Conductive sensors are very reliable, last a long time, and work well in muddy or rough water.

2. Soundwave Sensors

Ultrasonic sensors deliver sound waves to the surface and detect the time it takes for the signal to bounce back to figure out the water level. They don’t need to touch the water, therefore they’re great for situations when the sensor can’t touch the water.

3. Transducers

These sensors check the pressure that the water column in the tank makes. The pressure gets higher as the water gets deeper. They work great for deep tanks or wells when you need to take measurements by touch.

All electrical water level sensors transmit a signal to a control panel or automated system, which subsequently turns on pumps, shuts off valves, or sends alarms dependent on the water level. This is true no matter what kind of technology they use.

Why Electrical Water Level Sensors Are Important

1. Stop flooding and overflowing

The system may halt inflow pumps or open drains right away when it detects excessive levels, before water leaves the tank.

2. Prevents pumps from running short of water

Low-water detection stops pumps from running without water, which can cause them to overheat and break, which costs a lot of money.

3. Maximizes the benefits of the system

Managing water levels automatically cuts down on wasted energy, stops pumps from spinning when they don’t need to, and keeps the system running smoothly.

4. Less maintenance is required

Electrical sensors don’t have moving parts that can become stuck, break, or rust like mechanical float switches can.

Final Thoughts

To keep water management safe, efficient, and reliable, an electrical water level sensor is a must-have equipment.

What Are Fire Protection Systems?

Minimizing the risk of fire at your business or home is highly important. Read on to learn more about the different types of fire protection systems.

Business owners need to know how to be safe from fire. A fire can start in a flash and spread in a matter of seconds. When fire protection systems work as they should, businesses that pay for them get a lot of benefits. These measures help keep the facility, pricey equipment, papers, and goods from becoming damaged. Fire suppression systems, smoke detectors, and sprinkler systems are all sorts of fire protection systems that help find fires and keep people and equipment safe in buildings.

How a Fire Protection System Works

You should know how fire protection systems work. Different systems work in different ways, but they all have the same goal: to find a fire and keep the building, its people, and its belongings safe. A smoke detector and a sprinkler are two things that are often used to defend against fire. If a fire starts, smoke will set off the detector, which will turn on the sprinkler system. Water keeps the fire from spreading. This is a good way to do things, but when it comes to particular important equipment or special hazards, automatic fire suppression systems that use clean agents are a superior choice. These systems find and put out fires without leaving any trace.

The Advantages of Fire Protection Systems

One of the best things about a fire protection system is that it saves money in the long term. Think about a business and how much money it spends on things like infrastructure, manufacturing equipment, and IT hardware. A fire that stops work for a long time could cost a business millions of dollars. A machine shop that makes parts is a great example. The business would lose a lot of money if the shop caught fire and had to close for several days or weeks. You might have to buy new equipment, and you could lose important contracts. When businesses look at the expense of a fire prevention system, they need to think about all the elements.

Some types of fire prevention systems also have the advantage of automatically sending emergency services. These systems will work to put out the fire right away and let the authorities know to deploy emergency workers to your location.

Finding the Right Fire Protection System

How do you figure out which system is ideal for your business? You need to think about the building you are safeguarding, if it meets construction rules, and what insurance you would need. You might want to think about your facility’s future demands, not simply its current needs, because many fire protection systems are permanent. For instance, if you’re securing a server room and want to add more servers over time, can you add to the system?

When choosing and setting up a system, it’s important to pick a provider that knows exactly what you need and can tailor your fire protection solutions to fit those demands. You could be exposed to risk and downtime if your building isn’t up to code or your machinery and equipment aren’t well protected.

Fire protection That is Active vs. Passive

There are two types of fire protection: active and passive. When a structure is under construction, the contractor and architect can integrate passive fire protection, such as fire doors and fire escapes. Using materials that don’t catch fire during construction is another example of passive fire defense. Active fire protection, on the other hand, entails using a system that reacts when there is a fire. Fire sprinkler systems and specific hazard fire suppression systems are two examples of active fire defense.

Detection Needs To Work!

It’s also quite important to choose between active and non-electric fire detection. You don’t need power to use non-electric fire detection. You can be sure that your fire protection system will work even if the power goes out.

You should also think about the system’s features and any services that come with it. Will the system be able to detect things all the time? Does it let the police know when it goes off? What do you suggest for regular testing or inspection of the equipment?

Fire prevention systems are very crucial for keeping people, things, and buildings safe. A fire suppression system could be the best way to protect important machines or equipment.

Developing A Residential Fire Safety Plan

Developing a Residential Fire Safety Plan: Protecting What Matters Most

Being ready for a fire is one of the most important things you can do to keep your family safe. The last thing we want is to have a house fire. They can spread quickly and catch people off guard. The good news? You can keep your family safe, lower the risks, and know what to do in an emergency with a well-thought-out home fire safety plan.

We work at Waterline Controls to keep systems and property safe from water-related dangers, but fire safety is just as important for every home. Let’s go over how to make a fire safety plan for your family that works. Read on to learn more.

Why Every Home Needs a Fire Safety Plan

According to the U.S. Fire Administration, residential fires account for the majority of fire-related deaths each year. Most start in kitchens, but electrical systems, heating equipment, and even candles are frequent culprits. Without a plan, panic sets in, and precious seconds are lost.

A fire safety plan ensures:

  • Every household member knows what to do.

  • Escape routes are clear and practiced.

  • Fire risks in your home are identified and reduced.

  • Family members — especially children and seniors — feel more confident in an emergency.

Think of it as insurance for peace of mind.

Step 1: Identify Fire Risks in Your Home

First, go through each room in your house. Look for possible dangers such as:

  • Overloaded power strips or outlets

  • Space heaters too close to curtains or furniture

  • Candles left unattended

  • Old or frayed electrical cords

  • Grease buildup in the kitchen

Since Arizona has hot summers that make AC systems work hard, this is another place that should be checked often. Electrical and fire risks can be cut down with preventative upkeep.

Step 2: Install and Maintain Fire Safety Equipment

The first thing that will protect you are smoke alerts. Set one up in every bedroom, outside of all the places you sleep, and on every floor of your house. Every month, test them, and every year, change the batteries.

Other essentials:

  • Fire extinguishers — Keep one in the kitchen, garage, and near bedrooms. Make sure everyone knows how to use them.

  • Escape ladders — For two-story homes, store collapsible ladders in upstairs bedrooms.

  • Carbon monoxide detectors — Especially important if you use gas appliances.

Regular maintenance of water-based systems like sprinklers or backup water supplies can make a huge difference. That’s where companies like Waterline Controls come in — ensuring reliable monitoring and prevention systems are always working when you need them most.

Step 3: Create and Practice Escape Routes

Without mapped escape paths, a fire safety plan is incomplete. Make a simple map of your house, making sure that every room has two ways out if you can. Choose a safe place to meet outside, like a neighbor’s driveway or the mailbox.

Fire drills should be held twice a year to keep everyone sharp. For kids in the family, make the drill fun and educational so they will remember what to do when things get tough.

Step 4: Establish Emergency Contacts

Make sure that everyone in your family knows how to call 911 and what to say. You can put emergency numbers on the fridge or next to the phone. If you live in a HOA or apartment complex in Phoenix or Scottsdale, you should also know what to do in an emergency and who to call.

Step 5: Review and Update Regularly

When your kids get bigger, family members move in, or you do improvements, your floor plan may change. Every year, look over your fire safety plan and make any necessary changes. If you’ve added new tools, updated your HVAC or electrical systems, or updated your electrical systems, check for new risks.

Bringing It All Together

A residential fire safety plan isn’t about fear — it’s about preparedness. By identifying risks, maintaining safety equipment, practicing escape routes, and keeping the plan updated, you give your family the best chance of staying safe if the unexpected happens.

Let’s Get Prepared!

At Waterline Control, we understand how vital it is to have reliable systems that protect both property and people. Just like our electronic water level controls keep cooling towers, boilers, and tanks safe from failure, your fire safety plan safeguards what matters most — your family.

How To Install A Water Level Indicator

Installing a water level indicator can be a straightforward DIY project or a more technical job, depending on the type of system (mechanical, float-based, sensor-based, or electronic). Below is a general step-by-step guide for installing a basic electronic water level indicator system for a standard overhead tank.

🧰 What You’ll Need:

  • Water level indicator kit (includes sensors, control unit, wires, and possibly a display)

  • Power drill

  • Waterproof silicone or sealant

  • Electrical tape

  • Screwdriver

  • Cable clips or zip ties

  • Ladder (if the tank is elevated)

🪜 Step-by-Step Installation Guide

✅ 1. Turn Off Power

Always start by turning off the main power supply if you’re working with electrical devices.

✅ 2. Mount the Control Unit

  • Choose a dry, accessible location near the tank or inside your house (depending on the model).

  • Mount the control/display unit on a wall using screws.

✅ 3. Install Sensor Probes in the Tank

You typically need 3 to 5 probes (depending on your system), which measure:

  • Empty/Low level

  • Middle level

  • Full/High level

  • (Optional) Overflow or critical low

How to install:

  • Drill small holes on the tank lid or side wall near the top.

  • Insert the probes or float sensors to the corresponding depths (use the manual to know the exact position).

  • Seal around the holes using waterproof silicone to prevent leakage.

  • Secure the sensor wires with cable clips inside or along the tank body.

✅ 4. Connect Wires to the Control Unit

  • Use the labeled diagram in your kit’s manual to match each sensor wire to its terminal.

  • Typically, wires run from each sensor to a central controller unit via color-coded terminals (e.g., red = full, yellow = mid, green = low).

  • Use electrical tape to secure connections and prevent short-circuits.

✅ 5. Test the System

  • Turn the power back on.

  • Slowly fill the tank and monitor the display or indicator lights.

  • The control unit should light up or beep as water reaches each sensor level.

✅ 6. Optional: Connect to Pump

If your indicator supports pump automation:

  • Connect the pump’s power relay to the controller as instructed.

  • The system will automatically turn the pump on when water is low and off when full.

🔒 Safety Tips:

  • Always use waterproof-rated wires and connectors.

  • Keep control units protected from rain and moisture.

  • Don’t overtighten sensors; water tanks expand slightly when filled.

🛠️ Types of Systems You Can Install:

Type Difficulty Features
Float-based Easy No electricity needed; mechanical
Electrode/probe Moderate Common in homes; needs wiring
Ultrasonic sensor Moderate No contact with water; more accurate
Smart IoT systems Hard Remote monitoring via smartphone

Our level sensors and controls aren’t just for use in residential potable water holding tanks; some of the other applications include cooling towers, sump pumps, wastewater, boilers, water storage tanks, and building fire protection water tanks.

Float Switch Working Principles

How Does a Float Switch Work?

A float switch is a simple device used to detect the level of liquid within a tank or system and control equipment like pumps, alarms, or valves. Here’s how it works:

⚙️ Float Switch Working Principles

🔹 1. Basic Concept

A float switch relies on a buoyant object (the float) that moves up or down with the liquid level. When the float reaches a certain height, it triggers a switch—either opening or closing an electrical circuit.

🧰 Types of Float Switches & How They Work

🔸 Mechanical Float Switch

  • How it works: A float is physically connected to a mechanical switch.

  • Action: As the float rises or falls with the liquid, it moves a lever or tilts, toggling a microswitch inside the housing.

  • Use case: Sump pumps, water tanks, bilge alarms.

🔸 Magnetic Reed Float Switch

  • How it works: The float contains a magnet, and the switch inside the stem is a reed switch (a magnetically operated contact).

  • Action: When the float rises or lowers, the magnet moves near the reed switch, causing it to open or close.

  • Use case: Industrial liquid level sensors, HVAC systems.

🔸 Mercury Tilt Switch (older design)

  • How it works: The float tilts and shifts a small sealed capsule containing mercury.

  • Action: The mercury makes or breaks contact as it moves inside the capsule.

  • Use case: Less common now due to mercury hazards.

🔌 Wiring Logic (Normally Open vs. Normally Closed)

  • NO (Normally Open): The circuit is open until the float rises or falls to trigger it—then it closes and sends power.

  • NC (Normally Closed): The circuit is closed until the float changes position—then it opens.

💡 Typical Applications

Application Float Switch Role
Water pumps Turns pump on/off when water hits set level
Tank overfill protection Triggers alarm or shutoff if level too high
Aquarium sump systems Auto top-off to maintain water level
Industrial tanks Monitors chemical or fluid levels

Where To Put Check Valve on A Sump Pump
Regular Post
Written by webtechs

Where To Put Check Valve on A Sump Pump

A check valve on a sump pump is crucial for preventing backflow of water into the sump pit after the pump shuts off. Here’s exactly where and how to place it:

✅ Best Location for a Check Valve on a Sump Pump:

📍 Position:

  • Install the check valve on the discharge pipe, just above the sump pump, but below the basement floor level or first pipe bend.

Side View Diagram (Simplified):

House Exterior
↑
Discharge Pipe
↑
[Check Valve] ← ✅ Install here
↑
Vertical Pipe
↑
Sump Pump
↓
Sump Pit

🔧 Installation Tips:

  1. Orientation Matters:

    • Ensure the arrow on the valve body points away from the pump, indicating water flow direction.

  2. Use Unions or Rubber Couplings:

    • These make it easy to remove the valve for maintenance.

  3. Leave Vertical Pipe Space:

    • Leave at least 8–12 inches of straight vertical pipe between the pump and the valve, if possible, to prevent turbulence.

  4. Quiet Check Valves (Optional):

    • Consider a “quiet” or spring-loaded check valve to reduce clunking noises when the valve shuts.

❌ Avoid Installing:

  • Directly on the pump outlet—leave some vertical pipe.

  • Above floor level—water can drain back down the pipe and cause the pump to cycle unnecessarily.

Common Mistakes Made With Check Valves on Sump Pumps

Here are the most common mistakes people make when installing or using check valves on sump pumps, and how to avoid them:

❌ 1. Installing the Check Valve Backward

  • Mistake: The valve is installed in the wrong flow direction, causing no water to leave the pit.

  • Fix: Follow the arrow on the valve body, which should point away from the pump (toward the discharge line).

❌ 2. Installing the Valve Too High

  • Mistake: Placing the check valve far above the sump pit allows a large volume of water to drain back when the pump shuts off.

  • Fix: Install the check valve just above the pump, ideally 8–12 inches above the discharge port.

❌ 3. No Check Valve at All

  • Mistake: Omitting a check valve leads to backflow into the pit, causing the pump to cycle repeatedly and wear out faster.

  • Fix: Always install a check valve on the vertical discharge line.

❌ 4. Using the Wrong Type of Valve

  • Mistake: Using a swing check valve in a high-flow system can cause loud “water hammer” noises.

  • Fix: Use a spring-loaded or quiet check valve if noise or water hammer is a concern.

❌ 5. Poor Sealing or Loose Connections

  • Mistake: Leaky or improperly sealed joints around the valve may lead to water spray or air leaks.

  • Fix: Use rubber couplings with hose clamps or PVC glue (if using rigid PVC) to ensure a tight, sealed fit.

❌ 6. No Maintenance Access

  • Mistake: Installing the valve in a hard-to-reach place makes it difficult to service.

  • Fix: Use union fittings or quick-release clamps for easy removal and cleaning.

❌ 7. Valve Installed at an Angle

  • Mistake: Installing the valve at an angle can cause it to not close properly, allowing backflow.

  • Fix: Install the valve vertically for proper function.

❌ 8. Trapping Air

  • Mistake: A poorly vented line can allow air to get trapped, reducing pump efficiency.

  • Fix: Ensure there’s an air relief hole in the pump’s discharge pipe or in the pump housing, if recommended by the manufacturer.
