Every so often my Prochem water pump will act up.
I will lose pressure with very little flow and you can see and gauge bounce up and down and hear the pump knocking.

General Pump calls it cavitation, my water box is full and I put a new hose on from the water box to the pump. They mentioned to check the inlet check valves, so I will try that.

Any suggestions?

Thanks

Check valves are the place to start. It could also be the pressure regulator. Also clean the filter inside the water box using some acid. I had this same problem you are having a couple months ago and it ended up being the filter restricting the water to the pump.

A sticky float in the fresh tank can cause this also.
Tank can momentarily run out of water enough to cause problems with the pump but by time you get to the truck it can unstick refilling the tank properly.
