What is the difference between a spring check valve and a swing check valve?
It is easy to get swing and spring check valves confused, but they do serve different purposes. Swing check valves are forced close by backflow and spring check valves are closed by default, requiring more pressure to open their door and allow fluid through. Make sure you get the one you need.
Can you put a swing check valve vertically?
INSTALLATION: These valves should be installed a horizontal pipeline with the body vertical, using good piping practice. They may also be installed in a vertical pipeline, as long as the flow arrow on the body points up. Use a suitable joint compound or TFE tape on pipe threads for ease of fit-up.

Do I need a check valve?
The brass 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. ... The check valves pressure rating must exceed the maximum pressure of the pump
