PAylor Posted June 26, 2018 Report Share Posted June 26, 2018 Hi all, Our water pump does weird things. Most times no problem. Sometimes when you turn it on it runs without any water running. It stops by running water sometimes, by turning it off then back on sometimes, or by just turning it off. Any suggestions? Thanks in advance.

Kirk W Posted June 26, 2018 Report Share Posted June 26, 2018 An RV water pump has a pressure switch built into it that senses the output pressure. When the pressure builds up to 45 - 50# the switch turns the pump off. It sounds like yours has a pressure switch failure. Not sure what pump you have but some of them do have replacement switches available. Good travelin !...............KirkFull-time 11+ years......

elliott&vicky Posted June 29, 2018 Report Share Posted June 29, 2018 The pressure switches on most of them are very easy to replace. 2014 Redwood 36RE 2013 RAM SLT DRW, Cummins, ASIN 2001 Dodge SLT Cummins Link to comment Share on other sites More sharing options...
keepitlow Posted July 2, 2018 Report Share Posted July 2, 2018 OP...dunno. But I had a problem where my pump ran and water flow just dibbled out. I took off the aerator and it was clogged. Runs fine now. Link to comment Share on other sites More sharing options...

I took off the aerator and it was clogged. Runs fine now. I agree There is an input filter screen at the pump. Mine plugged after a couple hundred gallons pumped. Plus the pump inhaled some of the plastic sawclips in the system. I was unaware of the screen. Took the pump apart put it back together and worked fine. The outside hose sprayer would drip so I turned off that service at the Manifold. The pump still run intermittently. The problem turned out to be the Anderson 4-way valve leaking. DRV sent a new valve and I replaced it, problem solved. On a previous FW I had brought used, the pump would have run a little before the water would come. That problem required a new connector gasket on the inlet side of the pump.
