      Q:can this be used to seal off a toilet drain in the floor while working on the floor to keep the gasses from comming out

      Answer This Question

      A:  I don't see why not. I bought this for a cover for my main clean out because it was recommended by my plumber. Just make sure that the wider end is wider than your toilet flange so that there is no chance of it dropping in when tightening it down

          Q:If you are selling your home, will this actually pass a plumbing inspection? Seems like it's just meant to be temporary but this is a bit out of my wheelhouse.

          Answer This Question

          A:  I used it as a plug for the clean-out of the bathroom stack (the old one was actually a cork). A plumber put one just like it in the kitchen stack clean-out. They work. As far as what an inspector would say in the process of selling the house, I can't say.

          by|Oct 1, 2022

            A:  This is an approved plug but you will need to check with your local municipality to ensure it is approved in your area. These are typically used for testing or temporary plugging of pipe and not a permeant plug.

                So I just received the Oatey 33402 test plug and it works perfectly to plug the toilet drain. It is tight and I'm confident no sewer gas is escaping.

                  I use these for mineral feeders. I generally use them as the top and bottom plugs. I've had some in use for over two years. The pic is of an older design, I no longer put the little piece of pipe in the bottom, I just push the plug farther up in. It works better that way, less built-up.

                  The staff said there was no product in store to seal a toilet drain when removing a toilet, however when we did an Internet search this came up. I then found it on HD site and it was available in the very store we visited. Ended up ordering from a different location for pickup. It works great after all the back and forth to find it.

                  Initial viewing: Sioux chief The Gripper 4” Mechanical Test Plug is constructed using durable plastic wedge plates and a sturdy, pliable rubber sealing grommet. The threaded carriage bold and cast wing nut, are both cleanly threaded and operate smoothly. The top plate is 4 9/32” and will prevent it from falling into a 4” opening, while the bottom plate is 3 23/32” that easily fits in a 4” opening. Testing: I constructed a test pipe using 4” PVC piping, stepped down to ¾” steel nipple that I attached a 15 psi test gauge (see photo). I placed the test plug into the open end of the 4” pipe and then pumped in 15 pounds of air. The first test resulted in a fast decompression. I tested for leaks and found them around the plug. I tightened the plug to the maximum, using a set of vice grips and tested again. The second test resulted in a slow leak. I then made sure that the cut on the open end of the 4” PVC was exactly square and tested again. The integrity of the seal remained solid and it held 15 psi for 2 hours. Summary: I found this product to be made with excellent materials, the type that will result in a good long useful life span. Though the grommet is made of nice durable rubber, it is only 5/8” thick and needs to be exactly square against the walls of the pipe, to seal correctly. I would use this mostly for just temporally closing openings.

                  Works great for what it's designed for. As long as you have a clean, round opening, it will easily and securely seal a toilet drain or other open pipe.
