Fresh Water Tank Issue

[JLeising]

A thought I have had on this issue - I believe the internal water filter is plumbed AFTER the water pump. By so plumbing the internal filter, it filters both tank water and shore water. As a result, however, unfiltered water flows through the valve in question. I suspect dirt or sand could enter the valve and result in the valve sticking open. I use one of the "blue bullet" water filters whenever I hook up to shore water and when I fill my fresh water tank - avoids any "dirty water" flowing through the pump/valves.

Below is a couple of pictures I took with the valve opened and closed. Upstream to this valve is the water tank. You want to leave this valve open unless you have a valve failure in the water pump causing a reversal flow of water into the fresh water tank.

There is a screen on the inlet of the pump. I don't think we used to install it (years and years ago) but I recall that when we started, we found out it lengthens the water pump warranty with that installed.

Maybe it went from 1 year to 2 years.

Yep Brian, the filter keeps all the junk from getting into the water pump. The problem with the check valve stems from with either the pump freezing up over the winter or high water pressures from the park (and not using a pressure regulator). My pressure regulator failed on me last year which I believe is what caused my check valve to go but not 100% sure. Either way, I have a shutoff valve installed and a spare 4008 pump to change out if needed. Ohh, I also replaced the old water pressure regulator with a new one!
