How many check valves do I need?
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.
Can you use multiple check valves?
As long as all the check valves are new and working perfectly, you can get away with using multiple check valves. There are only two kinds of valves in existence, those that leak and those that will leak. The minute one of them starts dragging or leaking, which they will, many problems arise.
Where are check valves used?
When pressure changes in the piping cause flow reversal, check valves protect pumps and other equipment from damage caused by backflow. They are used in a wide variety of applications for flow control including, line isolation, priming pumps, media injection, maintaining head pressure, and many others.
