HWH hydraulic question ?

[skyguy62]

My 2 1/2" suction hose from the large resivoir at the back of the coach was recently replaced (Rubber had fish scaling and end fittings were leaking0. Subsequently on our road trip I have enjoyed a massive leak in the forward hwh compartment (as in recent postings quite a clean up process)that impressed ORA Las Vegas on my arrival!

The forward resivoir tank does not seem to have a filler opening; is it filled from the main resivoir (brakes and power steeing)? After cleaning the mess I tried cycling all the slides and Jacks and could not find a leak so I am assuming the main tank was over serviced. Driving in 100+ heat for the day then setting up must have led to the overflow. I have waited for two days to talk to someone at HWH. Thanks I cannot find any info in the few manuals I have on my "05".

Skyguy,

The HWH and the system in the engine compartment are 2 different systems. The HWH tank does have a filler opening, I am just not sure where it is on your year. Is it possible that someone topped off the HWH reservoir? If it was topped off while the jacks were down, it would overflow When they were retracted.

Cummins Cal Pacific in El Cahon did the installation, and said they drained and refilled the main tank only. That dip stick showed slightly over the full hot line. The small tank up front has only a 1/2 or 5/8 " thread bolt in the center of the top of the tank; no other opening is apparent. That bolt has a wiggily cap on the top of it, which I assumed was a pressure release cap ( if there is a hole in the center of the bolt (I did not unscrew it). The hole (after bolt removal) would be very small for adding fluid.
The system had never been serviced before so maybe it had always been very full and this was the first time I drove in 110 degrees; so perhaps I was overdue for the geyser?

That is the fill hole, a funnel is needed to add fluid. The bottom of the cap has a built in socket, to use on the valves when needed to manually retract a slide or jack. I don't think that the leak was just from expansion, I would look further.
