You said you "filled the tank". Do you have a tank fill valve by your city water hose inlet (not talking about the gravity fill port for the fresh water tank, but where you connect the hose for city water use in the RV)? If that fill valve is left in the fill position (instead of "city water pressure to the coach" position), the pump will just be circulating water back to the tank nonstop.

Did you open a faucet and let the air you left in the lines bleed out.

I mean I keep hearing the line about "Air in the lines" (propane) when a furnace or water heater does not work after several tries (This by the way is BS. Fridge its possible but not very. but for a Furnace or water heater it's BS)

BUt air in the water lines CAN indeed compress enough to prevent the pump from priming.

Also Some systems have a 3-way valve on the pump INTAKE (one more though too) that lets the pump suck pink stuff out of a jug.

Finally.. MY system the fresh tank drain is in the line from the tank to the pump. if I leave it open it can suck air.


Home is where I park it.

Worked fine to fill the hot water tank, but keeps running until I shut it off.

Did you try out "Emergency Repair Procedure Number One" ? Bang on the pump with something. Maybe the shut off is just stuck. Don't hit it to hard or you will bust it.

I fixed a lot of stuff in my day with that procedure.

Pressure Switch!
I don't know if you can buy one separately or not.
My old Aqua Jet just needs a few pieces but I have to send it to them/ 69.00 plus 69.00 shipping. So bought new one at Rally from factory for 149.00 and they put it in.
Ours did a little differently. It wouldn't shut off but no water until you cut the wter pump off and back on and you had water. Tun the faucet off and it still ran a bit of water but not much then none. Check valve and switch I think but they won't sell me the parts. I may pull it apart and see if it is just debris or something and keep it for a spare. Just make sure if someone else installs it they don't lose the screws to the cover plate and try to use wood screws. Amazing how hard it was to find stainless screws an had to substitute stainless cap screws.

Well after your post about air in lines I opened all taps and turned on the pump. After they were all purged with air I shut the taps and the pump shut off. I am one happy guy. Now it’s up for sale with a good conscience. Going to look for something smaller as we bought a place in Yuma for our 6 months down south in the winter.
