I'm putting in a new double vanity and am going to tap into an existing vent stack which was used for the old single vanity. Is it possible to cut the vent stack and somehow run both of my P traps into it? My issue is how to connect the P traps to it since I won't be able to use normal slip PVC fittings and be able to attach the last fitting. I'm guessing there's a way to do this. Help please.
Thanks. Looks pretty easy. Slip it on and tighten I assume.
Yes. Very easy to do. The more or less standard sizes of Fernco couplings are sold at places like Home Depot and Lowe's. There is technically a torque spec for the hose clamp screws (and even a special little torque wrench) but I've never bothered with that. Just don't seriously overtighten.
