Air operated dump valuve

[Wayne Kotila]

The air valve leaks can usually be fixed fairly easily by carefully taking them apart and paying close attention to exactly how the spool valve or valves come out to ensure you put them back in the same way. You just need to clean the spools and the inside of the valve bodies of any gunkthat may have accumulated and replace the o-rings on the spools withstandard o-rings found at any hardware store, lubricate with silicone spray and reassembly them. I have owned three Wanderlodges over the last 15 years and have had 4 air valve leaks in that time and fixed all of them by cleaning them and replacing the o-rings, If you can find the correct size o-rings the total repair to the air valve shouldbe under $1.00

Thanks, Jerry. The information helps me keep my 'Bird list updated.

Your bird and ours are pretty much identical other than colors.

I've experienced the two dump air switches leak and replaced them. The cylinder air hose/connections leak, removed the hoses, cut off about 1/4" and reinserted the hose to stop the leaks.

Have also replaced dump drain paddles.

Let me know if you need more information.

I'm acquainted with the folks that sold your coach to the King's. We shared stories for several years maintaining our coaches.

Good luck.
