Thought I would post this info about a leak I discovered when draining fresh water system for cold weather!
After removing low point caps, opening all the faucets, bypassing the hot water tank, removing the fresh water filter housing for drainage, this is when I discovered water in the water pump area on the vinyl floor. At first I thought it was from spilling the water from the filter housing. But there was just too much water on the floor in the pump area to be from the spilling of the water from the filter housing. In the Rockwood 2011,
mod 8285WS fifth wheel, the pump is behind the false panel in the pass through storage area. After removing the panel, I began to feel along all the fittings, PEC clamps in and around the the filter housing and water pump area. I am pretty good at always checking lines (water), fittings, pump, when I have the panel removed for any reason. It is just human nature for me as an old EX Navy "PIPE FITTER".
I discovered the valve that isolates the suction line from the fresh water
tank that enables you to winterize your fresh system with anti-freeze had a leak in one of the PEC clamps. The valve would turn "FREELY"
in the discharge side of the suction line. Also the fitting that "HAND TIGHT" screws onto the inlet side of the water pump was slightly loose and wet.
PEC fittings are great but if you do not have a PEC fitting clamp tool that cost $65-$98.00 and are not able to tighten the PEC clamp, you simply have to remove the clamp and replace it with a hose clamp that is applied with a screw driver!
It is advisable to check and inspect from time to time especially after your RV ages a little, the PEC fittings will become loose from compression of the PEC FITTINGS, especially the fiber reinforced flexible PEC LINES.
Thought I would post this information for all to read. It is a little long of a post but may save you some grief from a leak at some time
