G Green Drain Waterless Trap Seal, 2 Inch

Quickly and easily installs. Works almost as good as a real trap. Nice product

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

I think the bad reviews are for small drains. That said I’m using this in a 5” basement floor drain that goes straight into the sewer. My washer and utility sink drain into it, and it has no P Trap in the concrete floor. It smelled like the house sewer, stunk up the whole basement and house. Because of the immediate bend in the drain a Sureseal wouldn’t work. I popped this in and it’s been working for weeks without a problem. I’ve been very happy with it. I’ll probably buy a few spares, but it has been holding up to a house of 4 washing clothes, utility sink use, and a 3 Ton AC condensate drain line. It can handle a high flow of water, (like many many many gallons at a time) so I’m not sure what the negative reviews are about it draining slowly are about - probably bad plumbing and not the device itself.

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

Works like a charm

Works well, easy to install, as described, purchased two more after first one.

Summary, Works well at blocking odors, but drains too slow. This waterless drain trap is well-made and feels like a good quality item. It was easy to install - simply remove the drain cover and push it in and it seals well. It is also easy to remove by pulling up from the center. It works very well at stopping foul odors from coming up the drain. I think this would be ideal in a floor drain with occasional small amounts of water. I would NOT recommend it in a shower drain unless you have a water saving showerhead. My rainfall shower head lets out much more water than this can drain so it starts puddling quickly. Overall, it did not work well for my specific needs so I promptly returned it. COMPARISON: I have also used the sureseal brand of drain trap. The sureseal brand drain trap drains water much quicker so the water does not puddle at all. The problem with the sureseal brand is that the flap starts to sag after about a year of use and it stops working as intended and will not block the drain/sewer odors. For now, I will replace the sureseal brand every year if necessary until I find a more durable product that flows fast enough for my rainfall showerhead.

It does help to remove odors but using in a shower or areas where there is constant use there will be pooling of water as drainage is restricted.

عمليه جدا لكن ربما تحتاج تعديل وتصغير بسيط لتدخل في البلاعه

Just moved into a new house. We have a drainage hole in the floor of our furnace room. No P-trap, just goes straight into the sewage line. Stunk to high heaven. Smelled sometimes of farts, sometimes of animal, sometimes of both. Thought the smell would go away, but after a month it was only getting worse. Evenings our basement and main floor would smell like the inside of a public washroom. Did some googling and found out you can install one-way valves on pipes like this. Ordered the waterless trap seal, it came three days later, and bingo-bango no more sewage gas venting into our basement (which is also where we sleep, so SUPER happy to have this problem fixed). Rarely do I encounter problems in our new house that are this simple to fix. Seal's been in for a week now, and so far no issues. Drains as much water as I can throw at it. Poured several gallons of water onto it just to be sure, and it drained the water faster than I could pour it. So I have no worries about it being able to keep up with the drainage pipes I've got pointed at it right now (furnace, boiler, and dehumidifier).

Facile à installer plus d’odeur très satisfait

purchased the 3.5 inch waterless trap seal and works like a charm to get rid of any bad drain smells as well as stopping drain flies from coming out! highly recommend to anyone facing bad bathroom / laundry room smell issues!

The product would be 5 stars if they could actually get the dimensions proper as per the manufacturer's website. It is well built and sturdy design, but outer tolerances are off as I ordered based on fit range in millimeters from Green Drain website. I have verified my inside drain diameter, and it should have a slight friction fit, but instead just slides into drain without any resistance. At the moment I have cut a band from a bicycle inner tube, and wrapped it around the outside to provide enough friction fit so it doesn't fall down into the trap below.
