Im trying to get ready for boon docking and when I use my water pump it does not shut off when I close the tap . I inspected all of the joints that I could find both in the trailer and under the trailer in the basement where the pump is. As well as all the joints in the water tubes. Anyone got an idea of where else to look?
Thanks
Bob
Couple guesses.
Could be a leak somewhere or a bad pressure switch inside the pump, or the DC voltage is too low at the pump because of weak batteries or a bad connection somewhere.
When I run my batteries down real low the water pump won’t turn off.

Thanks again Ray…With the solar my batteries are right upto snuff so it’s not low batteries. As far as leaks, I don’t see any water dripping any where after letting the pump run for 3 minutes or so. I guess I may have to look at the pump to see if that is the problem.Cherrs
Depending on how much plumbing you have and how big a pump you have, sometimes it takes a while to get it all full again. Mine runs quite a bit if I’m washing dishes or showering. Do you mean it NEVER stops? Ack!

The pump head has check valves built into it. If a small piece of construction debris gets into the pump, it can hold the valve open, causing it to leak back and not develop full pressure, so it doesn’t shut off. Air leaks before the pump can have the same effect.
Are you testing this with your water tank full and city water disconnected? If the city water pressure is lower than your pump pressure, you could be pumping back into their pipes.I wonder if the winterizing kit (if there is one) valve is slightly open causing air to be sucked in. Has it ever been winterized Bob? Maybe water was left in the pump and damaged some innereds. Did that to my camper van pump once…
LoveYourRV.comIf I forget to switch the lever back from the tank fill position my pump will cycle on and off.
Good luck!
Steve..when you say move the tank fill position do you mean after filling it move into normal flow I.e. When using park water?
That’s correct Bob.
Steve….Thank you, Thank you it works. Just like that a little turn of the knob.
How are you with TV’s.
Glad that worked out for you Bob.
As for TV’s I am extremely experienced at watching them!
