I used this for an old floor drain clean out. The threads were all rusted and you could not put a new plug in it so I went with this compression type of plug and it worked.

The drain in our basement is poorly engineered, so if there's a lot of standing water in the yard, it tends to back up into the drain and sometimes even comes into the basement. It happened again just a few weeks ago, and my father-in-law suggested I buy a plug for it. I went to a local store and they had two sizes of plugs: 2 inches and 1.5 inches. The 2-inch plug was too big, and the 1.5-inch plug was too small! My wife saw one of these adjustable plugs online, but I was skeptical whether it would work. Besides, the only place it was available was nearly an hour away, and I didn't feel like driving that far in a heavy rain, especially if I didn't think the product would work.After the crisis was over, I decided to see if one of these adjustable plugs was available on Amazon. I was still skeptical, but since it was returnable, I decided to give it a try. It works like the proverbial charm! We've had a couple of heavy rains since then, so I put the plug in the drain. The plug was wet when I took it out, so I knew the water had backed up again, but the plug didn't let even a drop into our basement.UPDATE - I used it again this past weekend during a big rainstorm, and this time we did get a bit of seepage into our basement. I prefer "seeping" to "gushing", though, so that's okay! In fairness, I think I may not have had the plug assembled correctly. Make sure the plastic cylinder at the bottom is actually inside the rubber tube before you tighten it. I don't think mine was, and if that was the case, it didn't make a perfect seal.

I have an old condo that has a deck with a drain. Poorly designed because the deck is covered so there was no real use for the drain……Except in a hard rain the main water runoff pipe wasn’t large enough to accommodate that much water so the water would back up into my drain. It looked like a fountain coming through my pipe and all over my deck and the same thing happened to the condos above me who had left the original decks and not enclosed them like others had.. This was my solution. Even though the pipe was old and not exact size, this product fit perfectly and tightened down well. Hoping it will solve the problem. We’ll see in the next big downpour.

So it seals really well. Almost to well. I do alot of custom tile showers and pans as a tile contractor and After doing a 24 hour flood test in the shower pan this plug was so tight it was almost permanently stuck in the drain pipe. Took 30 minutes or more and 10 tools to pry this out of the drain hole. It should not be that hard to remove this drain plug. Was terrified of breaking the plug and having it get stuck inside the pipe. Yes it was that tight. So my suggestion would be try not to over tighten it or just pick a different plug all together. I am now scared to use this again and have since purchased another plug. The inflatable ones are better.

Used it to plug up a gasoline tank cap on a motorcycle, it worked very well and is built well enough to be used again and again. I really wish the best for the amazon workers and support unionization of these employees, its the only way.
