Holding tank odor...
My son's 2001 CC Allure has a persistent gray tank odor that permeates the coach interior within a few minutes of each departure. We have tried rinsing/washing/flooding/etc., the sink traps, washing machine trap/standpipe, shower trap and the black & gray holding tanks numerous times and are pretty sure that most, if not all debris, has been purged and all of the traps hold water. Yet the odor persists....
The plumbing on this coach looks in real good shape and probably rivals that found in an upscale home. There are four roof vents and we can detect the scent of bleach [which we used to identify which holding tank was causing the odor]in all of them. This would lead me to think there is a crossover vent between the black & gray tanks especially since we only put bleach into the gray tank. From what we can reach and/or inspect there appears to be no loose, cracked or broken pipes in the drain/vent system. There are also no [water] leaks under the MH either.
Any suggestions from our audience?
