Sump Pump Check Valve Location
The check valve is a minor part of a sump pump that makes a major impact in how effectively it functions. It is very important for keeping a basement or crawl space from flooding. A lot of people don’t think about the check valve until something goes wrong. However, where it is and how it is installed are very important for keeping water running in the appropriate direction.
Knowing where your sump pump check valve is and why it important will help you keep your system in good shape and save your pump from wearing out too quickly.
What a Check Valve for a Sump Pump Does
A check valve only lets water flow in one direction, away from the sump pump and out the discharge line. When the pump stops, water that has been pushed out might flow back down into the sump pit if there is no check valve.
Because of this backflow, the pump has to work harder and cycle more often, which can decrease its life and make it more likely to break down.
Where the Check Valve Is Usually Found
Most home systems have the check valve on the vertical discharge pipe that goes from the sump pump up to the floor joists or wall where the pipe leaves the house.
Most of the time, they are placed:
- A few inches to a couple of feet above the pump’s exit
- Set in a vertical part of the pipe
- Put in place before any big bends in the discharge line
This spot lets water drain correctly and keeps it from dropping back into the sump pit when the pump stops.
Why Placement Is Important
There are a number of reasons why the check valve has to be in the right spot.
Stops backflow
A valve that is in the right place keeps water from going back to the pit, which cuts down on pump cycles that aren’t needed.
Lessens noise and vibration
If a check valve is put in too high or at the wrong angle, water might flow back into the pipe and make loud pounding or “water hammer” sounds.
Makes pumps last longer
Less backflow means the pump doesn’t have to work as hard, which helps the motor and other parts last longer.
Problems with the Check Valve
Homeowners may not notice the check valve very often, but there are a few signals that it may need to be checked or replaced:
- When the pump turns off, there is a loud thump or bang.
- The pump turns on and off a lot.
- Water coming back into the sump pit after it has been pumped
- Leaks that can be seen around the valve connections
It’s a good idea to have the system checked out if you see any of these problems.
Choosing the Right Check Valve
There are different kinds of check valves. Valves of good quality are made to:
- Seal securely to stop backflow
- Work quietly
- Don’t rust or wear out over time
Choosing the appropriate part is vital, but so is making sure the valve is put at the right height and angle.
Keep Your Sump Pump System Working Properly
The check valve is one of the most critical parts of a sump pump system, and it is only as good as the other parts. Putting your pump in the right spot, checking it often, and replacing it when needed will help keep it from flooding and make it last longer.
