- Increases life of sump pump
- Included with every Basement Systems sump pump installation
How does a check valve work on a sump pump?
The check valve is there to prevent that from happening. The check valve prevents the pump from having to re-pump that water out which could result in short cycling. Eliminating short cycling will save on electricity costs in the long run. Pump Protection Short cycling causes the pump motor to run hotter.
How to add check valve to your sump pump?
Jan 09, 2020 · Why does a sump pump need a check valve? A check valve in the discharge of any pump is to keep flow reversing through it either by gravity or when another parallel pump on the same system is operating. Specific to a sump pump, it is to keep the water being held in a discharge line in place so that the water does not flow back into the sump.
Where should a sump pump check valve be located?
Jul 08, 2020 · Check valves installed higher up the discharge line can make fairly loud gurgle sounds. They can also cause the pump to enter a never ending discharge cycle. This happens when enough water flows back in the basin and activates the pump over and over. Best Check Valve for Your Sump Pump. The check valve installed by Crawl Space Ninja and sold on our DIY …

Is a check valve necessary on a sump pump?
Sump pump check valves are an important part of any sump pump system. Installed in the discharge pipe leaving your sump pump, the sump check valve prevents your pump from having to re-pump water it has already discharged.

Is a check valve necessary?
Check valves are an important component of every submersible pump water system. Why are check valves important? First, they allow your water system to maintain pressure when the pump shuts off. They also prevent backspin, up thrust and help minimize water hammer (more on this later!).May 14, 2017
Does a submersible pump need a check valve?
The check valve will help your water system maintain pressure when the pump shuts off and also prevent backspin, upthrust, and water hammer. It is recommended that at least one check be installed in all submersible well pump installations. Many well pumps have built-in check valves.Jan 16, 2019
What happens when sump pump check valve fails?
When a check valve is not installed on your sump pump's discharge line, a back flow of water can cause the pump impeller to rotate backwards and unscrew off the motor shaft. If this occurs, the motor in your sump pump will sound like it is running but it will not be pumping any water out the discharge line.
Why is my sump pump check valve so loud?
If you hear a loud noise every time you pump stops, you have a Standard Check Valve installed. That noise is the check valve closing which creates a slamming effect when the water flow reverses in the discharge pipe after the pump stops.
Do pumps need check valves?
Check valves are used in many different applications. For example they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps, the most common type of water pumps, are not self-priming, and therefore check valves are essential for keeping water in the pipes.
What is the purpose of check valve?
Since they only allow media flow in one direction, they are commonly referred to as 'one way valves' or 'non return valves. ' The main purpose of a check valve is to prevent backflow in the system. Figure 1 shows an example of a check valve. A check valve relies on a pressure differential to work.
Does check valve reduce water pressure?
Check valves do not reduce pressure, they actually help maintain it. In the setup you describe, it might work. However you will DEFINITELY need another check valve on the outlet of the tank to prevent the high pressure flow from backwashing in through the bottom, since there is no shuttoff/float valve there.May 16, 2015
Where should a check valve be installed?
The check valve must be installed at the outlet of the pump and in front of the outlet control valve for maintenance. Generally, the first outlet of the pump is the soft connection (shock absorber), the next is the check valve, and then the block valve.
What happens when a check valve fails?
Symptoms of a Failing Check Valve For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.
What is a check valve?
Most people are familiar with the operation of a check valve. It allows water to pass in one direction only. Some may call it a back-flow preventer. Its job is to prevent water or solids from coming back into the sump pump.
Can check valves be installed vertically?
Check valves can be installed in yard drainage, sewer systems and of course waterproofing. We recommend installing them vertically but some circumstances may require a horizontal install. The point of the valve is simple, prevent water from going back to where it came from. I hope you found this information useful.
What is a Jackel CH 150 check valve?
It is designed to be threaded on the bottom with rubber gasket on top. This design is easier for maintenance and removal of the discharge line to repair/replace the pump if needed.
