What is the purpose of a drop pipe check valves?

A check valve is a valve that is used to prevent backflow in a piping system. The pressure of the liquid passing through the pipe will open the valve, while any reversal of flow will close the valve.

Where should a check valve be installed on a well 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).

What’s the difference between a check valve and a foot valve?

Check valves and foot valves are designed to stop water from going backwards when the pump shuts off. Check valves are normally on the discharge side of pumps, and foot valves are on the intake of pumps. If a single check or foot valve is a good thing, one would think multiple check valves would be better.

Can you use a check valve horizontally?

Check valve can be installed in horizontal or vertical piping runs, with the flow running upward.

Is 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!).

What are the symptoms of a bad check valve?
