Smelly problem

[Wayne R]

I have had RV360's on mu coach for 8 years. I find them to be marginally effective. I installed a LiLStanker and have not had any issues since. http://www.lslproducts.net/IL-DSPage.html

Wayne, the new RV 360's are a vast improvement over the swivel ones. No moving parts. The LiLStanker is an interesting concept in that it provides negative pressure in the tank like the 360's do.

Yes it does and it can be on 24/7.

Mel,
Makes sense, but we don't have W/D so just as easy to glue cap in place so not to have a repeat problem. Many others in Alpine group have done same.
Regards,

The "vacumn breaker valves" on the kitchen and bathroom sinks are what is being discussed. I believe they are bullet proof, so if they work OOTB, they work all the time. Plus, that would only indicate a drain problem on those sinks, not a sewer odor coming into the coach when driving. Some owners report the vent pipes were not hooked up all the way from the tank to the roof, so taking off the vent cover, and shining a light down the pipe will help to determine if your is plumbed correctly. I get a sewer smell sometimes when hooked up to the parks sewer connection, don't know why, it goes away after few minutes, my feeling is parks don't vent their sewer lines enough and cause a pressure build up when someone close to me dumps their tanks. Otherwise my system works fine. You are going to have to check all the connections on your gray and black systems. Do the black side first, since that seems to be the culprit.

We have found that, those fleeting sewer smells in the RV are more often than not due to flushing the toilet when we have either our fantastic fan on in the bathroom or the other fantastic fans on in the rig.

Why? Because the fantastic fans create a under-pressure in the rig (they are pulling air out) so when you "flush" your toilet, once the liquid is out and the drain open, whoosh up comes the, well, smell from your black tank

Above has been verified by testing with Fans off and on. Fan off, no smell. Fan on, hold nose

What is being discussed is air admittance valves in the drain system of kitchen and bathroom sinks in some, (but not all), RVs.

Vacumm breakers are NOT used in sewage drain systems... (hey're used in fresh water systems to prevent the contamination of the city water supply).
