## Description

Oatey - 43745

Review: Exactly what I needed - I have a upstairs shower that has a faulty P trap and often smells bad. I had to clean the drain every couple of weeks only for it smell bad again. This drain trap fits perfectly in the drain pipe and immediately blocked the smell. So far no issues with slow drainage during or after I take a shower. I would recommend however just manually inspecting it every now then to make sure no hair or gunk remains on the drap trap after a while. Its easy enough to remove and give it good clean and or rinse and then putting it back in place. I like that no tool are required for installation except for a screwdriver which you need to remove your existing shower drain cover. Definitely money well spent as my P trap is not accessible to replace or repair without a major remodel. So this is a cheap and easy fix.
Review: Effective and so simple to use - I have been putting up with a smelly shower drain for more than a year. I got to the point where I thought I was going to have to cut the floor open to install a larger trap, but then something made me think to look for a check valve. This insert isn't specifically called a check valve, but in essence that's what it is. Water can flow in one direction - down the drain. Neither water nor odor can flow in the opposite direction - into the shower. It was extremely easy to install. I removed the drain grate from the shower floor, wiped out the inside of the drain pipe, and then pushed this little device into place. After that, I put the grate back in place. The insert didn't get in the way of the grate at all. It's very effective, too. Shower water drains unimpeded, and there is no more odor coming from the drain. This was a whole lot less expensive than a major repair on the drain trap. I am beyond delighted that I found it, and Oatey is a reputable brand, so I trust them!

## Questions & Answers

**Q: Will this work on an old drain pipe with a 2 1/2 inch inside diameter pipe?**
A: No, this would not fit on a 2.5 inside diameter.

**Q: Does it work in a shower drain without a p trap?**
A: My guess is that it should work in your shower drain. A P-trap prevents sewer gasses from entering the home. When full of water it is nothing more than a drain. Give it a try - can;t hurt. VERY pleased with the performance of our seal!
