It would be wise to chuck a 125mm non return valve in which would eliminate any back flow issues. Tbh I dont rate it as necessary in this set up. As said. The carbon filter would take care of it if the fan went off fornwhatever reason. Folks make it sound like it would be the end of the world if the fan went off Id be far more concerned about the smells coming out of the tent than the sewer. Firstly for there to be backdraft there need to be bakcpressure. Firstly to force the smell back up the pipe and secondly through the carbon filter. Now then fluid dynamics comes in here. Fluid take the path of least restriction. Which in this instance is right up the vent pipe because it lacks restriction that the carbon filter imposes. But there isn't any pressure forcing anything anywhere. It's just sat there. You've essentially just got a capped sewer with a carboncfilter capping it. And we're worried about smells Think about it guys. you make it sound like the sewer system runs at 2 bar Edited June 29, 2022 by blackpoolbouncer 2 Link to comment Share on other sites More sharing options...

Killuminati7 Posted June 29, 2022 Share Posted June 29, 2022 All joking aside. Unless u like lighting gas cans with matches I wouldn’t advise todo it’s against every code probably create a health hazard in the long run . Gud luck Link to comment Share on other sites More sharing options...
blackpoolbouncer Posted June 29, 2022 Share Posted June 29, 2022 Nowt like confident ignorance Tbf with a non return valve you would actually be following code @Killuminati7 explain how you think the smell can get past a non return valve and a carbon filter and which part of code it breaks? It's non standard application but nothing that breaks regs. Can definitely tell there's a lot of people in the thread that don't understand or have worked with plumbing/installing sewer systems 3 Link to comment Share on other sites More sharing options...
Killuminati7 Posted June 29, 2022 Share Posted June 29, 2022 Forget wot I said I’m on site now and the plumber said it’s fine to vent into stack aslong as u have an AAV an air admittance valve because of gasses etc 2 Link to comment Share on other sites More sharing options...
blackpoolbouncer Posted June 29, 2022 Share Posted June 29, 2022 (edited) The only issue would be finding an line air admittance valve. The only ones I've seen are designed to go on the end of a soil pipe. Hence the recommendation of a non return valve which does the same job Gonna blow some peoples minds that some soil pipes vent in a loft with nothing more than an aav. Fwiw it's not good practice to vent a fan into a soil stack. If you were a plumber venting a bathroom fan into it you'd be a bit of a lazy cowboy but we're working a non standard and not exactly best practice solution but what it is is a solutioncthats fine and works Edited June 29, 2022 by blackpoolbouncer 2 Link to comment Share on other sites More sharing options...
