Have an '83PT. Had a leak couple weeks ago which soaked mattress and board beneath it, headboard side of cross bed. No wet floor, no water in pump area. Hot water heater working fine. Took apart headboard and cannot locate any leak. (Has not leaked since.) Oh, Rain not a factor....dry here in Florida.
Any thoughts or advice? Thanks. George

George- did you happen to have a lot of humidity and condensation in your coach? Just an idea, Ernie 84 35FC

There are more ways to lose liguid from your water heater than you have fingers on your hands. My comments assume you have the original water heater and that your headboard is on the driver's side of the coach. First, the leak almost has to be associated with the water heater and its plumbing because other plumbing lines are below the bed level. First, make all checks with the water system under pressure, either city water hooked up or water pump on. Check the cold water flare connections before and after the check valve and the fitting into the pneumatic supply/drain valve. Check the hot water flare connections on the fitting screwed into the water heater. Check the coupling between the pneumatic valve and the water heater (prime area for leak due to galvanic action). Check to make sure there is no break in the engine coolant line for the motor aid and make sure the hose is attached to the pressur/temperature relief valve and make sure there is no leak at the low water sensor fitting in the heater. All heaters need captured air to accomodate expansion of the hot water. Without captured air,the water will expand and run out the P/T relief valve. To make a through inspection you will have to disassemble the driver's side rear cabinet and remove the closet floor to get to the water heater (not a big task). If you have an original water heater (now 17 years old) it needs to be replaced since its original life span is ten to twelve years. Its possible you have a leak in the city water fitting which is allowing water to spray up onto the mattress through one of the hand holes in the mattress board. Finally, make all your checks with the power turned off to the water heater. There are at least two electrical outlets in the heater compartment for other purposes, so switch off the breakers for these outlets.

George, this reply is a long shot but since you said your investigations indicated no hot water heater or water line involvement here goes. I had a leak in my 79 that was in fact a roof seem leak and it would build up in a little pocket and then let go. Very difficult to locate source but found it after a bit. Another source of water since you said there was no rain, is AC condensate leaking from an AC unit and running down roof line to the top of the bed.
I decidedly think these are long shots but still possibilities.
