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 has got to be the one of the best purchases I've ever made. After years of dealing with foul smells coming from a shower stall, this simple but yet affected device has all eliminated the odor. If you're experiencing something similar this is the fix for you and it's made by a reputable and purpose specific company you can trust.

Super easy to install, very good quality as I’d expect from Oatey and perfect to keep the bugs out! I plan to buy more. Just waiting for another price drop :-)

Needed a solution for drain gases. At first I thought this was clogging my shower so I removed. When seasons changed, gases started to appear, so I put back and no clogged drain and no smells this time! Think my shower was just clogged from construction waste at first.

I bought both the 3 inch and 2 inch ones. 3 inch works well in my laundry floor drain. The 2 inch was for the shower. It works but unfortunately doesn't drain fast enough for my 3/4 supply line shower. But not products fault just not a good fit for my needs on the shower.

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

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!

Works exactly as described

This is an excellent product! I had been trying to get a drain seal for my floor drain for some time, as my house is on the top of a hill, and due to gravity and having several bathrooms etc, flushing toilets in places further down the hill can suck the standing water out of the floor drain pipe in the laundry room which is at the top of the hill, causing sewer smell to come into the house. The hard plastic drain seals I bought before this are about 4 mil too big as the previous owners of my house wedged a 2cm length of pipe inside the existing drain pipe to attach the floor drain grate to, which can't be removed. As this Oatey seal is rubber, I have been able to insert it into the drain and create a seal below the 2cm section of wedged pipe, where it has been sitting for a number of weeks without moving. There have been spills in that room, and I am pleased to report that water going down the floor drain has not displaced it. Highly recommend to those wishing to stop drain smells coming up through floor drains - this certainly does the job.

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…!

Odors still seep through as the slit does not close properly even after wiggling it to best fit

Works as advertised
