Waterless Trap Seal, 3 Inch

Awesome, worked like a charm. Fit in perfectly super easy to install. Saved tons of time and extra money because of p trap not installed, this replacement worked perfect!

I got this drain to keep odors in my shower at bay, and I am very happy with the results. No more odors. At first, I installed it only one inch deep, and that caused water to pool. So I installed it at 2 inches as recommended, and the water no longer pools. I guess it needs the weight of the water that two inches provides for the flap to open and drain the water. I measured my drain and bought the appropriate size, so the fit and size are perfect. Regarding durability, I got this device some months ago, and I have not had any issues since. Totally recommend it.

This thing is a life savor. I have been covering my drain with an empty Walmart bag and setting a body wash bottle on top of it. Been like this for a year now. Embarrassing to have to explain to people who use this bathroom why they see it in the shower, lol. Anyways a buddy who lives up north was visiting and told me this can be an issue for people with basements and such and they use this seal to stop the issue. I live in Florida and never heard of this type of seal. So if you are silly and forget to install a pee trap under your shower pan, this is perfect for you.

Installed last night & drain smell was virtually gone by this morning! I live in a partially finished barn & haven't been able to enjoy my shop space (living room) due to the horrible sewage gas smell caused by no p-trap in an adjacent shower drain -- im confident that the smell will continue to reduce over the next day or so, even if the drain stop doesn't hold up long term as other reviews have stated, I'll 100% order again

This is supposed to handle negative pressure from a Radon System from the pipe, I just do not see that it would be able to resist much pressure. I think it would act fine for sealing outflow of gasses but I don't think it will maintain pressure against an Active Radon System for pipes leading to Sump Basin under negative pressure. Fit was good and seems like a quality product.

I bought the 3-inch G Green Drain to reduce odors and gases coming up through the drain, and overall it does what it promises. The fit was good — the size matched my drain as expected and installation was straightforward. Once in place, it effectively blocked unpleasant smells from coming up through the drain, which was the main issue I wanted to solve. It seals from the bottom up as described, and I noticed a difference right away. However, I think it could be improved if it also allowed water to flow freely from both directions. Currently, it works best for stopping backflow and odors, but it doesn’t allow water to pass downward from above as smoothly as I’d like. This would make it more practical in a wider range of situations. In summary, this is a solid product if your main concern is blocking odors and gases from rising up through your drain. Just keep in mind it isn’t designed for two-way water flow. Pros: • Easy to install • Fits as expected • Effectively blocks odors/backflow Cons: • Would be more useful if water could flow too to bottom

A very poorly designed trap. It has no top ring to keep it from sliding down the drain pipe. It relies on light friction to hold it in place. Run some soapy water down the drain and the friction was gone. After twice fishing it out of the pipe with a hook, I attached it to the drain grate with a zip tie. It did not drain freely and would allow the shower base to fill up with water. It would take 15 minutes to empty.

Easy installation and they keep they keep the sewer gas out great. No more smells from the drains.
