Odor Proof Floor Drain, Floor Drain backflow Preventer, Anti-Odor Floor Drain, Prevent Backflow, Prevent Odor Dispersion in Showers, Bathrooms, and Kitchens (2, 1.75''- 2.2'' Caliber)

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.

Easy to install when right sized to drain width. Installed in ground level shower drain in 60+ year old home. No more back-uo onto shower stall floor.
