Odor Proof Floor Drain, Anti-Odor, Prevent Backflow, Compatible with 1.75''-2.2'' Pipes, Modern Brushed ABS, Silicone Finish, Red

Works really well. Summer can cause pipes to emit less than desirable smells. This stops that.

Looks good！It is easy to install and very practical.

So happy with this purchase. I ’ve tried many of these types of drain trap seals like Oatey’s and I could still always smell a little of whatever was coming up my shower drain. However, this has a perfect seal, no smell coming up. I’ve been using it for months and would purchase again. The only con is I wish it was larger in diameter because I had to maneuver something so that it wouldn’t fall through since it was not wide enough and that also means water is slower to drain through the trap.

We have a floor grate in our basement that has been permeating a smell. After installation it seems that this has fixed the issue. Overall it was a cost effective solution and all we had to do was drop the peice into our drain. We have not needed to drain anything so I can only account for the device trapping the gasses.

we had a bad sewer smell comming out of the shower drain. this did the trick. after we put it in drain, the smell stopped and has not come back.
