Deodorizing sealing reducing ring, prevent backflow of sewers, filter and prevent blocking. Just install in every floor drain, like basement, laundry, bathroom shower, kitchen sink etc Review: It’s…not bad - After using this for a month I had to pop off the top mesh in my bathroom because the device was collecting hair like it’s designed to. I haven’t seen any drain flies pop up through my shower since installing this. And smell-wise no complaints as well. The only thing to note is it drains a bit slower but it’s not a bad trade off. Review: Poor fit water backing up - Product looked good several reviews so went ahead and purchased. Arrived and immediately saw problem with gasket it was not going to fit my drain. At this point I had already opened package and was suspicious of flow through device. I decided to verify flow holding under kitchen faucet and seamed ok. Decided to alter gasket to fit my standard Sioux Chief drain and install. At this point everything looked good seal was working after trimming. Turned on shower and within 10sec or less water was backing up maybe 1/2” in shower floor. This device would not handle flow from my shower and removed it. Before installing this device my drain flowed perfectly and was looking to prevent gases and smell from p trap. If you have low flow shower with different drain design than mine device may work for you, I will be returning with note about trimming gasket. Hope this helps you decide to purchase or not. ## Features - MULTI APPLICATIONS: This shower sink drain is suitable for standard 1.45”to 2.7" pipe.
