So having just returned from an multi day trip, the DW and I went out to do some cleaning at the MH, 2015 Hurricane 34E. We had the water pump on, and while she was doing some cleaning, noticed a puddle of water coming from under the bed. Took the mattress off, and got down and could clearly see water coming from the water pump area. Could not tell where, and it is very close quarters. Tried to reach down and tighten the two water lines, but it looked like it was coming from underneath the pump.I assume there are only two water lines attached, in & out....so is it possible the pump casing is cracked?

Also, as far as plumping....is the water only routed through the water pump inlet, through the motor and outlet when the pump is powered? Although I didn't have access to a water hook up, if you are connected to city water, is the pump and associated lines bypassed? We just returned yesterday, and had no issues on the trip, so this is a fairly new development....but we also did not use the pump that much either. At least it is still under the new warranty...

Cheers, and thanks,
Tom

Do you have a water pressure regulator connected, an adjustable one with a meter is preferred. I have seen water pressure play havoc with connections in a RV if the pressure is very high. You might not notice this right away.

I found the body screws and come a bit loose and needed tightening on my water pump.

I do have a regulator, not a dial one though... and I am not sure what the body screws are...seems like the body is a molded piece, but not sure.....lot of stuff in that bay under the bed, and hard to get a good look down there.

Thanks guys, appreciate it.

The outlet side of the waterpump is under pressure when connected to the city water. The diaphram in the pump head acts as a check valve to keep the water from reaching the fresh water tank and causing it to overflow. Most pumps are rated to 60 psi. Any higher pressure may cause the diaphram to leak, but more likely overfill the FW tank. Your leak is probably a loose hose clamp or one of the lock type fittings that the hoses are attached to. If there is a strainer inline they also can leak if the cap isn't securely attached.

Should be much higher than that. The RVIA standard pressure test for RV water systems is now 90 psi, if I remember correctly). My Aquajet water pump is even rated to deliver 60 psi if I crank the adjustment up (45 psi is its default setting).

It is possible the pump casing cracked, but that is not a common failure. More likley a loose or broken fitting at the inlet or outlet. Or at the tank outlet itself.

It seems the output pressure isn't related to the inlet pressure. Aquatec
gives a max inlet pressure of 60 psi on their installation instructions.

Ok, went back out and double checked the lines and clamps everything seems tight I need to take it in for another issue, so I guess I'll add this to the list!
Thanks
