OateyOatey-43745, No Size, Black

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!

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 beautifullyI am a person who looks at reviews before buying and I would definitely recommend this item…!

Works as advertised

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 purchased to reduce noise from shower drain that's about a foot above the P-trap - does a good job. Easy to install. Hope it lasts. Seems expensive for what it is.
