Fresh water leak

June 15, 2013, 05:13:37 pm

I have developed a leak somewhere in the fresh water system. This results in a drip from the passenger side of the coach, from the area of the manifold. There is no water on the pump/reservoir side of the partition; only on the manifold side.

The leak produces about a pint or a bit more overnight. The leak occurs without any water in the fresh water tank and the system fed from the fresh water inlet. I closed all the valves on the manifold and the leak continues. I am suspicious that the leak is at the inlet valve for fresh water or at the valve controlled by the tank-fill switch.

Any suggestions would be appreciated.

My hot and cold drain valves  leaked and were replaced.

Have you removed the panel in front of the manifold and checked it's tubing connections? Have you been using the shower? Is it water from the shower drain p trap or even the hot or cold supply to the shower?Gam

We recently had a leak in the shower drain. We found it when there was water dripping in the wheel well area

NO - I CAN SEE ALL THE BATH CONNECTIONS THROUGHT THE ACCESS PORTS UNDER THE VANITY IN THE BEDROOM. THE DRIPPING DOES NOT STOP IF THE SHOWER IS NOT USED.

Just wondering.

Based upon my recent experience in replacing the pex tubing on the curbside of the utility compartment as part of my bulkhead project after having the tanks, pump, water heater, etc. out, I would say check the seals in the pex swivel connectors. Most of my old ones were in sad shape, and even with new swivel connectors on there, I sometimes have to reseat the thing a few times to get it not to leak.

Is it leaking with or without pressure? You may need to disconnect the accumulator to verify.

I had to do a whole house regulator because if pressure went above 60 psi my pex fittings started leaking all over. I stay under 45, no problems ever.

If you have to change any fittings on your pex lines the "Sharkbite" fittings that you can get at Home Depot work great! They are expensive, but easy to use and you can take them on  and off with no problem. I have used them several times with no problems or leaks!!
