Service time

So after my trip to Florida I decided it was time for some service, since the rear bathroom had a horrible smell I found the sewage line from the rear toilet was cracked,I must have not got enough antifreeze in the line, and of course that line is in a wall behind the toilet and runs through a shelf along the floor to the vanity,got that fixed today was a 2 day job,found the generator exhaust hangers broke and replaced them,now the big question the engine a/c quit working so I recovered the system and only got 10 oz out of 2.5 lbs I took a uv light from the compressor in the rear all the way to the condensor and evap could not find any oil leakage or dye anywhere so I pulled down a vacuum and put 1 oz of uv dye and recharged it to 2.5lbs works again was 63 degree in building and 40 at the vent, so has anyone have ideas where or how to find the leak?

Odor behind bathroom vanity

Hello: We have a 2014 Thor Hurricane 34 F. We have a very bad odor coming from behind the bathroom vanity ... similar to your problem. Can you tell us how we find out exactly what is BEHIND the vanity? Is there any place we can get schematics of our RV? Many thanks!

The last time I spent a couple weeks (off and on) trying to find a slow leak, it was on the plug on the top receiver/dryer. I finally found it with a sniffer and the UV die did not show the leak as it was in a low pressure part of the system.

Owners resource center on the Thor website. If the schematics are not there contact Thor and ask for them.

The flush line for the black water tank runs behind the vanity in my freedom traveler. Have you ever used your flush line for black water rinsing? Something may have backed up. You also may have something in your vanity drain line. You can try a septic tank safe drain cleaner to see if that helps.
