I removed my toilet exposing the flange on the floor. In order to diagnose
an odor problem, I need a test plug that can enter about 2 inches into a
pipe (pass the flange) and then plug it. The pipe-flange junction may be
leaking, that's why I want to plug it deeper.
I went to lowes and the only test plugs there plug the end of the pipe. Any
The flange hole is 3-inch, straight, not offset kind.
You're probably looking for an inflatable test plug. They come in various
sizes to match the pipe diameter. You stick it in the pipe and inflate it
with a tire pump to seal it tightly, then fill the pipe with water. When
the test is done, let the air out, and the water will go down the drain.
(in my case, I was pressure testing the whole house for a new install, and
had a four foot high water fountain out of the cleanout plug in the
backyard. :) ).
I've never seen these at Lowes or Home Depot, I had to get mine from the
local plumbing supply store (you could probably find them online). My store
had a great return policy. I purchased the plug (about $30 total), used it
for my test, and was able to return it when I was done. Kind of like
renting, except I had to pay for it up front.
For that matter, you might even try a rental store to see if they carry
Hey, I was going to say that.
Also, stuff a big sponge in it. I guess those have pores but Im not
sure they go all the way through. And if it it is compressed enough,
I would think they would be squished shut.
Or maybe better yet some compressable closed foam. I don't know if the
stuff that comes in packing boxes is closed or not, but I save it for
times that I'll need foam.
You're only trying to contain odor, not water, so it doesn't have to
be physcially strong.
Find a solid rubber ball that will just go in. Drill a hole through the
center. Install a long bolt with washers and a wing nut. Insert ball with
bolt in middle of pipe. Tighten wing nut to expand ball.
