Review: Great solution to stinky shower drain - 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!
Review: Life saver - 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 .

## Questions & Answers

**Q: does this stop actual water back up or just the fumes?**
A: I think it is meant to only block fumes but probably would at least limit the amount of fluid coming back.

**Q: Does it catch hair?**
A: There is also a filter screen in the accessories of the floor drain, which can stop the hair.

**Q: I know this is gonna sound silly but i have no experience in this type of field where do i measure so that i am getting accurate size? need help**
A: You only need to measure the inner diameter of your drain pipe, and see if you can place our floor drain with the width of the inner diameter. Then you can use a tape measure to measure the depth of the pipe and then select the appropriate size of the floor drain. You can see the picture of our products

**Q: 99% of households apply?? Most shower drains around here are 2” id and I see this says 1.55 to  1.77 “hole”... Is this a mistake? or is there a 2”?**
A: Hello, this product is aimed at small water pipes, the size is less than 2 '', between 1.55-1.77''

### ⭐⭐⭐ Make sure you measure your drain twice to get the right size.
*by T***L on June 5, 2022*

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.
