We have had leveling problems over the last year which were finally solved by replacing the raise valves on the front HWH “six pack”. We had been to a couple of service places that improved the situation but never really solved the issue.
Partly in order to freshen the look of the coach, and partly so it was drivable at night, we decided to have a headlight “conversion”. At the same time we decided to have the tail light conversion in order to complete the look.
Our HWH pump began to cycle more frequently than normal so it was time to search for air leaks. We found one of push fittings attached to a check valve leaking and replaced it with an higher quality DOT approved fitting. We also replace a few of the other fittings in that area (HWH Pump Bay) for good measure.
From time to time the leveling solenoids on the front and rear hwh six packs develop leaks. The leaking of the o-rings is easy to find with the soap bubble test, and replacing them an easy project. Leaks inside the valves, at the seats, or internal o-ring, can be more difficult to diagnose and often exhibit themselves as leveling issues.
Our Magnum Opus VacuFlush toilet was taking longer than typical to pump down to the shutoff vacuum. Some of that was due to the higher elevations here in Santa Fe, but some of it was just age.
I ordered an HWH minor service kit and set of brushes so I could do a rebuild of the pump to make it “like new”. The minor service kit arrived after a couple of months of waiting. The brushes however have not arrived and the manufacturer does not seem to be in any rush to make any.
You would think that the most difficult thing in replacing a mattress would be to dispose of the old one. In this case that turned out to be the easy thing to do, the difficult part was actually getting the old wildebeest out of the coach.
After paying almost $50 for a 4 ounce bag of indicating desiccant at FoT, we did some research to find some lower cost options. This desiccant is used on the outlet of the HWH pump to dry the air before its used.
