G Green Drain 1.5" Waterless Drop Seal - Black Silicone Floor Drain Plug

Did the trick, no more drain smells....

Stopped the smell, but also stopped the water flow, now I can't remove it as it's suctioned stuck! Will have to spend £100s to get this device removed from my pipe by lifting the shower tray up.

Works great! Definitely worth it and the size was correct! I like the way that if your basement did flood it has a “valve” that will open to let water down the drain but it won’t let fumes up into the space.

Facile à installer plus d’odeur très satisfait

The product would be 5 stars if they could actually get the dimensions proper as per the manufacturer's website. It is well built and sturdy design, but outer tolerances are off as I ordered based on fit range in millimeters from Green Drain website. I have verified my inside drain diameter, and it should have a slight friction fit, but instead just slides into drain without any resistance. At the moment I have cut a band from a bicycle inner tube, and wrapped it around the outside to provide enough friction fit so it doesn't fall down into the trap below.

Very helpful item

purchased the 3.5 inch waterless trap seal and works like a charm to get rid of any bad drain smells as well as stopping drain flies from coming out! highly recommend to anyone facing bad bathroom / laundry room smell issues!
