Annual Trailer Inspection

Our trailer is one week shy of being a year old. I took it to the dealer for a check-up. I wanted to establish an annual trailer inspection routine. I had prepared a list of deficiencies, a list of inspection items, and I had arranged for the installation of a slide topper. This was to be the first Annual Trailer Inspection.

RV Air Admittance Valve

It is quite likely that your RV is equipped with an air admittance valve. The AAV acts like a vent stack in your plumbing to provide “air after water” to allow efficient draining and to prevent siphoning of your p-trap. I was plagued with a recurring grey water odor in the cabinet under the kitchen sink of our trailer and it took me a long time to track down the culprit. It was a failed RV Air Admittance Valve (AAV).
