Flush mount black tank vent?

Hughes has a vent for both sinks and one for the tank.

If it's a single tank you should be fine with the valve.

If you go with the HEPVO valves, you can eliminate all but one of the black tank vents, not sure how many you have, but I have three and will be
eliminating 2 of them... once I get to that project.

One direct to tank and 2 that go to the sinks

How about the marine side? What do they do? Would something like a marine fuel tank vent or something work?

I dont do boats over 22 feet, not sail powered and not less than 2 hulls....lol.

Rich,

The codes for fuel tank vents are completely different. RV codes are minor revisions of BOCA.

I used an AAV on my bus conversion and something inside failed. I replaced it with a more robust model and had the same result. I am not sure the
reason for either failure BUT I had to do a work around to get rid of the odor.

Just my experience.

Good luck on whatever path you take.
