Waterless Trap Seal, 2 Inch

I live in an old property in France and the shower drain unit was never fitted with a " P " trap so the smell from the wastewas foul. I came across this product on Amazon.fr , from the States, reading the reviews it seemed that this might well be the answer to my problem. It arrived and looked well made, fitting was very simple. I have to say I am extremely pleased with the result since fitting it. IF you are experiencing this issue then I strongly suggest this is most likely to be the answer for you as well. Delivery was very really quite quick.Alan

This worked perfectly for me! It's sealed in any smells that would emanate from the drainpipes, and the water drains thru it with ease. I was concerned by some of the other reviews but rolled the dice with the product. I can whole heartedly say I'm glad I did!

New to us townhouse has a stinky basement shower drain. Every time one of the 3 toilets from anywhere in the house flush, stinky fumes would come out of the drain. My investigation tells me a working p trap was installed and there was no evidence of clog or blockage in the system. Stink is most probably the result of an inefficient vent system in the drains. More costly solution was to install another vent = $$$.I stumbled upon this product while researching solutions for my problem. Installation took less than 5 mins. Pop the drain, make sure drain pipe is clean, drop this device into the pipe and push to make sure the rubber “fins” provide a good seal around this device and the inside wall of the pipe. Ran the shower full blast for around 5 mins to see wether water pools on the floor which may indicate draining is slowed down. Surprisely, no change. So I filled up a bucket of water about half way and dumped everything into the shower floor while shower was still running. Water initially pooled in the floor but was gone in a few seconds. Yehey! There’s no significant slowing of water draining!Before I installed this device, I read reviews that say draining slowed down to the point of water pooling on the floor while taking a shower. That was my biggest concern. Almost everybody was saying this product kept the stink out but had that issue of slow draining. For those having problems witn slow drain with this product, try pushing the device deeper into the drain. That will help build more water pressure between this device and the water on the floor. Also, it may help using a shower head that is one of those water efficient kind rated for 1.5 gallons per minute.Very happy to get rid of that annoying stink!

This does not help reduce odors in any way. I have a walk-in shower and the drain can give a bad sewage gas smell at times. I got this product after cleaning the drain and doing everything I could to help reduce the smell. This item has honestly helped 0%. Even if it would have reduced the smell a small percentage I would accept the results. But 0%? That's just a waste of $35 that I wish I could have back.

I was pleasantly surprised by how quickly the product arrived, and it was packaged with great care. The item actually fits my drain perfectly, which is a relief. I bought it because of issues with gas backing up, and it effectively prevents any unpleasant odors from permeating the bathroom or the entire house. The quality of the item is evident, it's well-made and sturdy. However, I deducted one star due to the pricing, but overall, I would highly recommend this product to others.

It was cheap, and it stops the sewer gas odors. This is perfect for rental properties or those where you cannot modify or change the existing plumbing/septic WC vent design to eliminate the problem. I had the same issue as a few where it did not move adequate water for a shower drain. If this is you:1. Drill (8ea) evenly spaced pilot holes-horizontally with a 3/32 drill bit along the lower recess portion where it says, "made in china."2. Redrill those same holes with a 5/32 drill bit, and drill out the hole in the center piece from the bottom.3. Deburr and remove shavings.4. Do NOT drill your fingers.5. Install as directed. If this does not help, anything else you install either will not make the odor go away or drain sufficiently.

Helps big time.

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.
