Holding Tank Smell

[Ryan Wright]

John,

I don't have a washer/dryer in my '86 PT-40. That said, I DO get stink
coming in - from the center cruise-air!! I don't know how or why but
the center unit sucks in stink once the holding tank gets partially
full. I can smell it pretty bad coming right out that A/C vent. Turn
off the cruise-air and the smell mostly (not entirely) goes away
(except for the lingering smell that's already been sucked in). Or,
dump the holding tanks and then I can use the cruise-air smell-free.

It also seems related to movement of the coach. I spend time in the
coach on a daily basis even when it's just parked at home and I use
the facilities, so the tanks slowly fill up over several weeks. Under
those conditions there is rarely any smell. Once I start driving,
though, within half an hour or so the cruise-air starts sucking it in.
Now I go straight to the dump any time I leave the house (I need to
get an RV dump installed at home).

I'd love to know how to fix this... I replaced the manual dump valve
seals last year because "stuff" was leaking through and making a mess
when I took the cap off the dump port. I figured that was the source
of the smell, but the new valves are tightly sealed (yay, no more
embarrassing dump incidents!) and the smell remains (boo...).
