TP123 Pneumatic Hydraulic Test Plug Inflatable with Air or Water, 1-1/4" to 3" Inch

There’s not a lot to say about a product like this, it either works or it doesn’t. And this one works. I was able to plug my shower drain for inspection while remodeling the basement and this held the water back for 12 hours while doing my leak test. What more could you ask for? I would recommend hanging the handle off a nail or screw though, the nylon “leash” will put an insignificant amount of water on the floor, due to capillary action, if you just let it lay over the edge of the curb. Won’t matter for most people I’m sure, but it was an observation that I made while using it.

Exact as described and works well!

This was an heirloom quality plug and it'll last a long time.... awesome!!!

Works good when I need the job done

I purchased this stopper to plug the overflow standpipe when plunging my bath tub. Otherwise the force is dissipated away from the drain. It is easy to use. You insert the balloon and inflate it with an hand pump or regulated compressor. Very little air is actually needed for a tight seal.

This product (G.T. Water Products, Inc. TP122 Safe-T-Seal Test Plug, Fits 1-1/4-Inch to 2-Inch Pipes) worked great to plug my 2" drain needed to perform a 24-hour leak check on my new mortared shower pan. It is very easy to use: Simply insert it into the drain and pump it up. I used a hand-powered bicycle pump and this worked well. My leak check was successful, so this product obviously sealed the drain well.For added ease-of-use, I purchased an extension hose from Amazon also: G.T. Water Products, Inc. TPH4 Extension Air Hose, 4-Foot. This allowed me to inflate the unit more easily.

It works ok if you use it right at the end of a pipe. However, if you need to push it further into the pipe, like past the Wye joint in an outside septic cleanout, be aware that you will need a special extension air hose that is long enough and designed to be used with a ball like this. The other is that the pull out strap is only about 38" long, which kept me from pushing the bulb past the wye joint and into the main pipe. I suppose you could tie a longer rope to it.

The shower test went ok in that the seal was %100 and I passed the test on the shower I'm building, but I tried to use a hand pump as suggested. It will lose the smallest amount of air on disconnect and that will let almost all of the air out of the plug no matter how much you pump. Also, even the quick pressure check lets out too much air. So, I hauled my compressor in and it did the job, but at what psi I'll never know.
