This worked like a charm. I inserted it into 1 1/4" septic pump drain pipe and put in 39psi of air, and it stopped the waste water with no issue...of coarse the pump was shut off. This is a great tool to have...

Works great. I used it to plug a toilet so I could soak the bowl with cleaner to remove some iron stains. Only downfall is that the air valve is under water so you have to reach in there to empty the air out to remove it. It should come with a valve extender.

Worked just as described for our shower pan inspection, and it was much less expensive than purchasing locally.

We purchased this in order to check a leaking pipe coming out from our .75 acre pond. Most of the water had drained out but there was still some coming out. My husband was able to use this test ball to plug the pipe and find the leak. They fixed it and now the pond is full again. This plug was invaluable to us. My husband loves his pond which was a gift (the building of it) from his deceased mother. thank you

During severe storms our sewer line can back-up into the house due to storm water migration. I use this plug to seal the basement toilet from the bowl side to avoid removing entire fixture. Works great, good quality!

I tried using a balloon to do a water test on a shower pan liner that I've seen on a video. the balloon popped after a few minutes. the ball is expensive but worth it. very easy to use. just set the ball in the drain. pump it up using a bike tire air pump. i believe i set it to 30psi. remove the bike pump and fill the shower pan with water. Mark the water level on a plastic cup filled with gravel and let it sit overnight. lucky for me there were no leaks.

While I was not 100% sure how much air to pump into the ball (I just used a hand-pump for bike tires), I erred on the side of caution to avoid bursting the ball or cracking the base of my PVC drain. Ultimately, I just pumped enough air into the thing to make it "snug" in the drain, and it worked like a charm!

My shower had back flow coming up through it. My toilet would start gargling and then here comes the sewage threw the shower drain. I wasn't sure if it would work because of several factors but it worked for my situation. The toilet will gargle but nothing else. This plug has saved the day.

This works excellent for checking your shower pan liner seal. After you do you pre-slope you silicone your liner to the drain X out the hole fold down the flaps, X slice the holes for the bolts make sure there is silicone around each bolt hole and bolt down the drain. MAKE SURE to keep weep holes clear..i stick wire in them until the silicone dries. Use a Bike pump to blow up the test ball not a compressor as it takes very little air. Make sure to put rocks around your drain when doing the dry mix bed so water can drain into the weep holes.

Great for performing 4 hour shower pan tests! A bike bump and 1-2 ft hose is needed to plug your drain at a deep enough depth to bypass weep holes.
