Can this be used down a 3” wye fitting and will it seal or does it have to be used on a Tee type ...
Asked by Ian December 28, 20175
AnswersThe ring you see on the picture prevents closure of any fitting. I couldn't figure out how to go backwards up the wye and still be able to inflate the plug. I ended up cutting the pipe. I saw a long plug advertised that may have worked on a wye.
Will this fit into a toilet bowl to prevent a potential sewage backflow?
Asked by Rich April 28, 20174
AnswersNo! Bad idea!
How large is the ring, that it’s supposed to prevent from falling down the sewer?

Asked by Eric January 18, 20173
AnswersRV'ers use a special pink antifreeze that can be used in your case. If there is a chance of freezing you'll need to shut the water off, flush the toilet until all the water is out of the tank and most of the bowl. Vacuum out the rest of the water in the bowl, then dump in about a 1/2 gal of pink RV antifreeze. It can also used in the sink & tub/shower drains as well. You would of course have to have a way to drain all the supply lines as well. Don't forget the washing machine water line, ice maker in the refrigerator, dish washer lines etc.
How long is th chain?
Asked by Ray September 15, 20173
AnswersThe chain is about 12"
i live at 6000' feet altitude. four inch cherne test ball will not seal pipe @ 13lbs psi
Asked by fishhooks April 26, 20202
AnswersRead the instructions. I think you can inflate to 30 psi.
will this seal when inserted in the middle of a DWV Tee?
Asked by jdp January 30, 20172
AnswersYes, You'll need to feed it up into the pipe and the ring will set inside the female opening. You need the extension to remove pressure without putting your body parts inside the pipe. If its an open pipe under test the plug may come out, make sure no one is in the path of an open pipe.
up to what pressure do you inflate this for a good seal?
Asked by TomH May 30, 20202
Answers30 psi worked for me

December 7, 2018
The Cherne 4 in. rubber test ball plug is well made, I used an air hose extension with it to make it easier to use & inflate. I got this 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 holding pressure for the inspection. 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 1 foot chain & ring to grab it out of the pipe or prevent it from going down the drain (pun intended!) Make sure you read the instructions as there are a few safety issues with this unit.
The ball needs 30psi to blow up and can be used for up to 13 psi max back-pressure in the pipe. It was shipped double boxed with packaging to prevent it from bouncing around. The instructions are in English, Spanish, & French. Made in the USA

November 13, 2020
In most applications you need an extension hose added on. It would be better for the manufacturer to include that in the package or least for HD to have it on the shelf, rather than having to order it separately from someone else.

The description says it can plug test tees, but what it doesn't say is that you have to shove the plug sideways into one of the branches of the tee. You can't just push it into the middle of the tee and have it seal the whole tee.

Perfect for my 3 1/2 clean out drain. I ran an condensation pump from my furnace/ac unit and used this to plug the drain. It saved my basement from the 2 great flood of spring 2020.
