Holding Tank Smell

[Rob Robinson]

Yes I'm really pleased with my 120 mile first test run without that Watts valve but it may not be the final and complete solution. I never did believe that opening an window at 60mph would suck fumes through a P trap but there still may be other sources I haven't found yet. The overflow orfice in the toilet comes to mind. Who knows. I'll be sure to let you all know what I find out as I travel south this winter.

Hey Rob,

You were right on the money here, you figured it out first.

No brag, just fact!

If I were you I'd be rather pleased with myself.

If you had not of told me about the Watts valve I would have never

figured it out. I installed the LilStanker tank vents the week before
I re built the W/D closet they were running 24/7.

When I unhooked the pipes the vent fans were turned off and it was
obvious the was the source of the problem. During the install of the

new check valve and pipes I switched the vents on and the smell went
away.

Now I'm thinking I really didn't need the tank vents, now that the
source of the tank smell has be discovered.
