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

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
