Oatey 4013846 2 in. Dia. Plastic General Purpose Floor Drain, Black

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.

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!

This had an excellent fit and blocks odor and bugs. I was a little skeptical before purchase, but, after installing the item I could feel the quality and matched it work. Awesome little fix, thank you product maker!

We live in a newly constructed home. After a year we noticed that the standing shower started to smell, and mold started growing under the silicone caulking. I stripped the moldy caulking, re-caulked the entire shower. After 2 weeks the mold was back. I was starting to guess that it might be the drain and p-trap. I purchased this Oatey seal to test my theory. Installation was a breeze, it just pops right in and fits snugly. It helps with aesthetics of not having to see a white pvc pipe in the shower. The water drains without any issues, I've never had any build up. Finally, it's been over 3 weeks and no mold in sight. Fingers crossed this continues to do the trick!

Super easy to install and stop sewer smell from coming out, but still allows water to flow through when shower is on.

Works!! Measure correctly and set it into the drain. Problem solved! Excellent product

Doesn’t really Block any odors. Says I might get charged a restocking fee but how would I ever know if I don’t take it out of the packaging? The piece that is supposed to stay closed is open. Looks like the rubber doesn’t completely “close” and just seems to stay apart allowing odors to come through.

It definitely helped block the odors that were coming from my shower drain. I highly recommend this product if you have the same issue.

Works exactly as described

So we don’t have pee traps in our plumbing Contractor forgot to put them in so after a year we have been getting a back up of sewer smell, short of, ripping out walls and floors to fix the problem we found this magical little device to put in to the shower stall , and it has worked beautifully I am a person who looks at reviews before buying and I would definitely recommend this item…!

Works as advertised
