Water Pump Issue

[Mick_309]

Hi All, hoping for some advice.
My water pump is not holding pressure and when on water is coming out of the mains hose input. I have checked all of the lines and clamps and it all seem air tight. Could it be a non return valve issue? I have a 2013 20.63.1 OB
Thanks in advance
Mick

Further to that even with the pump off there is still water dripping out of the mains inlet

There are non return valves in the water inlets sounds like one of yours either has something stuck in it holding it open or it has failed, they are easy enough to pull out and check.

Yep, inside the plastic bit where you hook the mains onto is a NRV, just remove the fitting and pull the NRV out of it and put the fitting back in place and add a George Guest NRV in the line just down from the fitting that will fix the problem, removing the faulty bits will mean it won't restrict flow........Guest NRV is about $15.

I had issues with mine sticking causing me to have no mains pressure so I put some Vaseline on the non return valve rubbers and now it works like a treat every time

....Handy Hint #69.......If happens when on the road, and using your tanks then just connect hose to mains fill and other end to tap on draw bar with tap turned off then no water leak and pressure good...........then you can fix at your leisure.
