Shower floor drain backflow preventer one-way drain valve magnetic core insertion drain plug (1.10-1.77 inch aperture) (suitable for pipe depth of 2.56-4.13 inch) ((1.1-1.46in Hole) Depth 3.15in)

Perfect solution to a stinky shower drain! We always had to put a cover over the shower drain when it was not being used (must not have trap under the cement floor!) This only took a minute to install and works perfectly. It allows the water to drain easily (even at full flow) and prevents sewer gas from coming up through the drain. Highly recommended!

Love this. It’s so easy to install and no more smell in the basement drain.

I did measure my drain twice but I still screwed up on the drain size. So I had to send it back it was too small for the drain I was trying to put it in. I did not reorder yet, but I probably will if the problem still continues.

Didn't work!

I installed this in my shower. It’s a neat design and I’m sure it works ok for low flow applications....however for my shower...it didn’t drain fast enough and I was left standing is a puddle.

I'm a professional plumber and I'm currently renting a real nice place all except for one thing the landlord used someone who didn't know what they were doing when they remodeled and they didn't install a p-trap in the shower, if you know anything about plumbing you'll know this keeps out the sewer gas from coming into your home. I knew he was to cheap to jackhammer out the newly remodeled shower so I found this little gadget and for all intensive purposes it does a fantastic job. Does clog with hair frequently but small price to pay .

si tienes mal olor por el desagüe de tu baño te recomiendo esto,sólo coge bien las medidas porque ordené uno más pequeño y tuve que capsarlo con una junta de goma extra pero me funcionó de maravilla, espero que los plomeros conozcan esto

too small for 2" drain pipe
