Mechanical Test, Seal & Clean-Out Pipe Plug - 1-7/8 to 2-1/4 in Marine Boat Scupper Steel DWV Testing Anti-Return Winterizing Pool Plug with Galvanized Screw & Nut for Most Pipe Sink Pool

Works great and seals good

Used it to work on my pool. It created a very watertight connection.

I bought this to plug our dryer vent in case of flooding. Hurricane Ian put 16” of water in our home in FL! We now have flood barriers but must also plug the drummer vent which exits our block home about 2” above floor. With the large handle, it’s possible to tighten by hand and seal. It worked during H Milton where water was 6” over floor level! All storm surge fro Gulf which is 15 miles downstream!

Good quality, does the job. Had a hard time finding the right size until I ran across this particular brand.

I bought this to use as a temporary plug for a 2" PVC. So after inserting it into the pipe, I tightened it down as far as I could. As soon as I turned on the water in the system, water started squirting out around the plug. I tried readjusting it. etc. but it never made a tight seal. When I removed it and looked at it, I saw that the rubber compresses unevenly as you turn the handle, which results in leaks around the plug, making it useless. You can see this unevenness in the photos here. You can also see how the washer compressing the rubber is not at right angles to the center bolt, leading to the uneven compression. So I am returning it as it didn't work for me.

Used it for a kitchen sink trap plug, works great.

well made, easy 1 hand operation and sealing abilities

But issue is it only works on a couple size pipes. No good for a bathtub overfill no good for anything to do with the kitchen.
