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)

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

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.

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

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!!

Buen producto hace su trabajo

Muy pequeños y el agua se va muy lenta.

Works very well. Water from HVAC condensation goes down and odors do not come up.
