I got this CHERNE 2 in. Rubber Test Ball Plug to test the waste drains in my new plumbing coming from a bonus room over a garage that has a bath, kitchen & laundry room. It's well made and does the job. It only takes a small bike air pump to fill it, I even used one of those handy car starting battery's that includes an air pump. It's well thought out having the long 3' air hose & ring and chain to grab it out of the pipe & prevent it from going down the drain (pun intended! LOL) The ball itself needs 45psi to blow up and can be used for up to 13psi in the pipe.or 30' of water pressure. It was shipped double boxed with packaging to prevent it from bouncing around. There instructions are in English, Spanish, French and I think either Chinese or maybe Japanese? (don't quote me on that!)

This is just what I needed. I am building a new shower and need to seal the drain to test the shower pan installation. This fits easily in the 2" drain line and inflates with air pressure to form a good seal so the shower pan can be filled with water for leak testing. The instructions say inflate to 40 PSI but that is for back-pressure testing which I will not be doing. Less PSI will give me a good water tight seal to prove I have no leaks. Unit comes wit a valve cap that will remove the Schrader valve for quick deflation. Unit has a safety chain and loop. Wear safety glasses and hardhat! Nice product!

Cherne has always made a great product and still do. This long 2" rubber test plug is excellent for testing the joints & 2" pipes on lines that are made out of cast iron. A great product for the professional but can be used by the D-I-Y'ers. Comes with long extension tube to use to inflate deeper into pipe for safety. Also comes with a retrieval chain to remove the tool after testing and after it is deflating. Depending on the internal shape & textures of the pipes one has to always check the body of the plug after each use to make sure there are no cuts or damage. As with all pressure tools be safety minded. The product will wear out eventually. I've used these before and now needed a new one.

Got this test ball for pressure testing a 2” drain lines for leaks under stress some up to 30 feet long. I like the fact that there is about three feet of airline you can attach to it to be able to stay back while your inflating it. With the ability to use a hand air pump or compressor to air it up it makes the install easy. It is heavy duty enough to withstand the demand I will be putting on it in the future. Will be putting on it in the future.

This 2 inch rubber ball plug is a great addition to my Plumbing toolbox. Mostly use these for testing for shower pan leaks. Looking forward to using it for its proper application. lower in the plumbing at a Wye situation. I just use a bicycle pump to pump it up. Let it sit for 24 hours. If it has a lower water line, the problem is before the bar plug.
