Temporary closing PVC drains

Nov 16, 2008 8 Replies

I'm building a bathroom wall and need to install a new PVC double san-T (2") in the vent stack before installing the wall studs. What do plumbers use to temporarily close off the open pipes for a day or two? I heard a wet rag will work to slow sewer gases, but I may need something better yet not permanent. TIA


I would think that an expanding rubber plug should work well, try a boat store like West Marine if you can't find one at your local hardware emporium.

Also you ought to find a rubber cap that tightens with a hose clamp, like a Fernco with the end closed off.

Go to a plumbing supply. They sell expanding plugs for that purpose.

On a new clean fitting and ring, we always just used a couple layers of duct tape. This wasn't just for the smell, it was to keep debris from falling down there. It's not a pressurized system, so you don't need much of a seal. It should work on an open T in the wall as well, since liquids won't be hitting it even if there is another drain upstairs.

Duct tape or a rag is all that is needed. If one wants a better looking, just a plain end cap slipped on without gluing does it.

rubber glove and a rubberband?

Plastic bag and a rubber band works for me.
