Does a submersible pump have a built in check valve?

Does a submersible pump have a built in 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.

Where is the check valve on a submersible well?

Check Valve Located at the top of the pump to prevent back flow into pump and hold the head of water in the system.

Where do you put a check valve on a submersible pump?

In submersible pump applications, the first check valve should be installed directly on the discharge head of the pump or maximum one pipe length (20 feet) above pump. Water pumped and flowing through a piping system has a certain amount of energy (weight x velocity).

Where should a check valve be installed?

Check valve can be installed in horizontal or vertical piping runs, with the flow running upward. Mounting for vertical installations is critical.

How far should check valve be from sump pump?

Best height ( unless owner’s manual states otherwise) is two to three feet off of the top of the sump pit. This way your sump pump motor doesn’t have to work as hard as when your check valve is in lower position.

Do Wells need a check valve?

A Check Valve Is Required For A Water Well. It’s important to understand the components that make up your homes water system in order to maintain it and keep clean fresh water flowing safely into your home.

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 required on a sump pump?

Without a sump pump check valve in place, all the water in the discharge pipe empties back into the sump pump pit liner. This causes the water level in the liner to rise. Higher water levels in the sump pit liner causes the pump to run more often, increasing energy costs.

When do you need a check valve for a submersible pump?

Multiple check valves are required in a submersible pump application. For every application a check valve should be installed just after the pump and one at the surface. In cases where there is a check valve built into the pump, another one should be added less than 21’ above the pump or 25’ above the bottom of the pump.

Why do you need a check valve in a well pump?

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.

Why do you need a submersible well pump?

A submersible pump allows for moving water from the ground up. They are designed to push the water up to the surface in a very efficient way. 2. Check Valve The placement and number of check valves required for a system is based on the depth of the pump setting in the well.

How tall should a check valve be in a well?

 Install check valve vertically with arrow pointed up in direction of liquid flow.  Also, a check valve shall be installed no more than 25 feet above the lowest pumping level in the well. 200 feet or less One check valve on pump discharge and one on surface of well.
