Fresh Water Pump Quit Working

My fresh water pump quit. Checked the inline fuse at the pump and it's good. It seems like the pump switches doesn't activate the pump. Any help with any more fuses to check or anything else to check. 2009 Bus 43'

Thanks Lee and Carol

What type of pump is it and what make and model unit do you have. If it is a ShureFlo demand pump and you are sure you have power., the pressure switch in the head of the pump could have stuck or failed. Give us some more information on your unit

Yes I had 12 volts. I will check the pressure switch tomorrow but I really don't know what to look for.

If you have power to the pump, it's likely the pressure switch contacts. I was able to get mine to work til I was able to replace it. Switch contacts are accessible under the end cover... Just remove the 4 screws. Center screw is the pressure adjustment. Gently file/sand the contacts and reassemble. I kept my old one as a temp spare.
There are some improved pumps available now that you may wish to consider. Click image for larger version

I have a Kemco AquaJet pump. If I ground it to the frame the pump runs and
the light at the switches come on. I was told the switches are hooked the ground and the 12V wire stays hot all the time at the pump. Does anyone
know if the ground has a fuse at a switch? Are any where I should look for
a fuse or anything else to look for.

Thanks Lee and Carol

Are you grounding the base of the pump or the wire? If you ground it can you shut it off with the switches that light? It almost sounds like you are bypassing the pressure switch. If you ground the wire will the pump shut off when it gets up to pressure or does it just continue to run? No, there should not be a fuse on the ground side of the circuit.

Hi Dsallach
I'm grounding the pump ground wire but i won't shut off with the switch. It
does shut off when the pressure switch is up to pressure. I tried to ground
on of the pump switches and it would only work when i hold the switch in,
when I let go of the switch the pump stops. Something must of happen to one
of the grounds on a switch but Lord only knows where. I could ground the pump and let the pressure switch turn it off but if it ran out of water or had a
leak it would keep running and burn the pump up, so I know that's not the
correct way to fix it. To me it's a complicated system when you can mash one of the four switches to turn the pump on and the light comes on all four switches, then just mash one of the switches again to turn pump off. Works
great when its working I'm just not smart enought to fix it.

Thanks Dsallach
Lee and Carol

Hi lee, I agree with Old Biscuit. From your narrative the pump and pressure switch sound fine. The relay is the suspect at this point.

My low side relay came in, installed in a couple minutes and the pump works
perfect. I want to thank ever one for all the help. Cheap easy fix when you
get the right info.

Thanks Again Lee and Carol
