Holding Tank Smell

[Kurt Horvath]

Leroy,

I think I have located and repaired the source of the holding tank
smell with the widows open while driving. The Watts valve on the Black
Tank Flush system. This is a feable device and mine permitted air to
pass in both directions. Once I dissasembled the device the aroma was
overpowering. The fix thanks to Rob, is a check valve and an enclosed
system. I have gotten to test it yet due to my coach being down with a
major exhaust system overhaul. I'll let you know ASAP if it worked.

Kurt, you are way inventive and inovative, in most respects on the
cutting edge. Its gonna be hard to top RobR's cure for stink. I
plan on just removing the atmospheric vacuum breaker and thru pipe
it. check valves dont make code and noone ever hooks and leaves the
tank wash appliance un attended. Thanks for the info. if it doesnt
work I'll just say "RobRobinson" when visitors ask "whats that smell"

I'm really beginning to think I made a mistake telling you two about my "possible cure". Especially you Greg VBG

I figured what heck the one way valve was a few bucks, just closing
the pipes would be good enough I'm sure. Get the CD yet?

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.

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.

Thanks Kurt. I have studied my prints throughout this thread and I don't have a Watts valve listed in the parts section, and have never seen one. It's most likely location would be behind the washer dryer wall in my coach.. My plumbing prints are also not as built in several ways. The prints show two vac-u-jet roof vents, I have one roof vent so I guess my vents are tied together somewhere. My prints show two check vents near the sink water traps; I have two. My kitchen sink and shower go to the gray tank. The toilet, vanity sink and washer dryer go to the black tank. I like this configuration because the tanks are almost always balanced out and the washer dryer keeps the black tank clean, no monitor problems. I do not have any problems while driving even with a window open if I close the drains prior to departure. I do not have any problems while stationary, except when using the shower with the Fantastic fan on. If I crack a window with this fan on while using the shower there is no problem. Strange deal. So I close the drains when driving, and crack a window if I chose to use the Fantastic fan while using the shower. I seldom use the thing because it sounds like a jet plane. I like the old Kool-O-Matic in the kitchen much better so it gets used often.. I still think the vent checks allow air into the tank system while driving so the vac-u-vent will work; but I do not intend to tear the coach apart to figure it out. I cannot see how the vac-u-vent can work without inlet air. To make things worse, the vac-u-vent operates in a semi-vacuum environment at best, maybe worse. lmo I am glad you found your problem. This must be an ongoing problem because of the differences in the coaches and related plumbing. One other thing, I never use any deodorant in my tanks.

I have a 1985 PT-40 and when I open the windows I get that smell seems
to be from behind the slide out cabinets right next to the washer on
the curb side. Is there some valve behind the washer that is bad?

John that's where I found the WATTS valve on mine. It was behind the W/D and accessed through a panel
