air toile compressor is failing

[brad barton]

My 2000 LXi just has the small 12v compressor, no pancake tank. Not that we didn't have trouble with it. Ryan rebuilt it when we bought it, then we eventually had it replaced. Finally, we both found a small air leak at a fitting under the lavatory, on near the wall and one near the toilet.

I am convinced those toilet air pumps wear out from overuse because of minorleaks in the air lines. Since they pressurize only briefly, the leaks are hard to find. The quiet 12v pumps probably run when we don't notice them. Our Newell didn't have a 12v only the main 110v aux compressor. It was not only huge and loud, it wasbolted througha boardontothewall ofthe engine compartment about 16" below the nightstand on my side of the bed. And with air-leveling bleed-off and the leaks in the other air lines, it rana couple minuteseach hour all night. After the first night, I was ready to take it back. We eventually moved it up front.

You mighttighten up the systemby hooking a separate air line onto the pump, putting constant (not too high) pressure through the lines and finding the leaks probably in some valveor fitting somewhere probably hard to reach.

Our 2000 LXI is now on it's 4th compressor. After spending over 400$
to buy the first replacement from BB, we went directly to a Thomas
distributer for #3 at about 245$. That 1st replacement from BB lasted
nearly 5 yrs. #3 we shipped backed to Thomas last fall for a warranty
replacement and it is in storage until #4 goes down. Fortunately #4
is still running but we have found that we have to drain/purge it
frequently to eliminate that awful noise. It seems to require it more
when you have high humidity or fog. Thomas can't explain why they
fail, they just refer you back to their distributer. Otherwise the
microphor has been OK.
