Sewer Vent - Event Date: 05 Dec 2017 - 06 Dec 2017

We do intend to use the wet bath exclusively at camp sites. So that might push our usage up a bit more than most as I gather most people tend to try and avoid the use of the wet bath when possible. Part of the reason we purchased the trailer is to avoid public restrooms in the time of COVID. But still, we've got no smell to force the use of this vent right now.

Y'all are convincing me that I should probably just cool it and wait until I have a problem before I try and solve it. 

As my daddy always said, "if it ain't broke don't fix it".

I have had smells in my wet bath, as have many others. The usual cause is letting the traps dry out from lack of use. That won't be your problem with 4 people using the bathroom. Be sure to wipe the bath down and dry everything out after showering and get any wet towels etc out of there, otherwise it will stay damp all the time and grow mold.

If you do the math on how much positive pressure at the top of a vent stack from the wind it takes to push air past the water in a trap its very unlikely that that could ever happen. Direct Cat 3 hurricane winds still exert less pressure than a one inch water column. Traps are designed with at least 2 inches of water seal.  In my house on the NC Outer Banks I never once got a sewer smell even in the strongest blows. 

I have gone weeks with 1/2 full black tank and never get a smell. You might want to wait and see. Now one thing that makes a difference is your septic treatment. All treatments are not created equally. My personal favorite is from thetford, it's called Aqua Kem. It's a thick gooey blue liquid. It costs a little more than some others, but, I think it's well worth it. I tried 3 or 4 different types (with bad results, odors) before settling on this one. Others will recommend other things, but this is what works for me.
