2Pcs Odor Proof Floor Drain, Floor Drain backflow Preventer, Shower Plug, Magnetic One-Way Drain Valve, Prevent Odor Dispersion in Bathrooms, and Kitchens (1.5''-2.0'' Caliber)

Works really well. Summer can cause pipes to emit less than desirable smells. This stops that.

After only a month since we finished building out a garden unit in our place in Chicago a monster rain storm backed up the gray water septic pushing water out the laundry room drain. Not good. Installed these in shower and laundry room floor drain to prevent that some happening again. Fit great for this application.

Excelent product, seal good, good value for the money, works well.

We rent our home, and the P-trap in the main shower stopped working, causing unpleasant sewer odors to seep into the house. I tried every backflow product I could find—most managed to block the odor but left me standing in ankle-deep water because they slowed the drain. This product, however, is a game-changer. It completely eliminated the sewer odors and kept the water flowing smoothly. Highly recommend it for anyone dealing with similar issues! Time will tell how long it lasts, I suspect I’ll have to replace it eventually once the magnetic valve wears out.

So easy to clean out of the shower compared to others that I have used!!

Muy pequeños y el agua se va muy lenta.

False advertising. Arrived with no magnetic closure, had a cheap spring that doesn't hold door closed. Returned. Waste of time.

Buen producto hace su trabajo

So happy with this purchase. I ’ve tried many of these types of drain trap seals like Oatey’s and I could still always smell a little of whatever was coming up my shower drain. However, this has a perfect seal, no smell coming up. I’ve been using it for months and would purchase again. The only con is I wish it was larger in diameter because I had to maneuver something so that it wouldn’t fall through since it was not wide enough and that also means water is slower to drain through the trap.

Buen producto, solo que lo usé en otro lugar no para el que fue comprado ya que no revisé bien las medidas

Las dimensions no son exacts. El products es mucho mas pequeno de lo descipto. Inutil

Was supposed to come with an adapter for 2in drains. Did not come with it so now I can’t use it.

i was impressed by its fit for 1.5 inch ABS pipe, it was perfectly tight. I am slightly sceptical of how it would fit on a bigger pipe as the adapteur is silicone only so quite soft. the small door has decent strenght but not enough to not open for water. one minor negative point: the small door does not have a rubber or silicon seal, it is plastic to plastic so a little bit of air could leak but very little
