Shower Drain Floor Drain Backflow Preventer Magnetic Levitation One-Way Drain Valve Fast Drainage Shower plug Insert Drain Plug Fit for Tube Depth 2.56-4.13in (Caliber（2-3.9in）,Depth 3,15in)

this product works great for me. i live in a tiny home with no pee trap in the shower. I also only have a small 20 gallon hot water heater and use a low pressure shower head with low water adjustment turned down to save water since I enjoy my hot showers.. this product drains good even with low water pressure going in the drain.. the only time it drains slower for me is because hair has accumulated in the hair catcher.. once cleaned it drains great and back to normal.. the cleaning is very easy, just pop off the drain cap in shower and clean filter and unscrews the valve and check to make sure no hair is there to be cleaned out,, very easy and quick just a few minutes of my time.. i do recommend this item if your willing to do quick maintenance on it.. 5 stars for me,, it was needed,, no more smell,,

I used this in my condo utility room, where the vertical washer/dryer combo fits. The original drain in the floor is partially situated underneath the heavy washer, making it impossible to access the drain for cleaning. Additionally, the pipe lacks a "J" hook to prevent sewer gases from entering. So, I wanted something that I could only raise the washer/dryer unit up one time to remove the original drain screen and replace it with one that would seal out gases and any potential cockroaches, while having access to the one-way valve in case my water heater broke or the lines to the washing machine broke. This fits perfectly on the outer circumference of the floor and the inner circumference of the drain, without applying any pressure to the drain from the washer. I tested the drain by pouring a 2-gallon bucket of water on the tile floor (as if the water heater or hose to the washing machine had ruptured). The drain worked perfectly and quickly cleared the water from the floor; I no longer have a sewer issue. I also installed an alarm on the floor that contacts my phone and a digital security camera for remote viewing. Alexa automatically turned off my water heater pipe to prevent continuous water from entering the utility room. This setup has given me peace of mind when I'm away from home. I highly recommend this inexpensive solution to solve my unusual situation.

I was happy with the result. Eliminated the sewage odors as advertised. Didn’t back up like others stated. Of course you have to clean the hair when you see it. Otherwise no issues. Toughest part is cutting it to size. Others were correct in saying it breaks easily when cutting so it cracks all the way through to the base area. Still managed to salvage it and it works well.

Great idea, too bad it doesn't work. In my shower, the water doesn't open the door until I manually kick it or mess with it with my finger (which misses the whole point of this thing). Once the door opens, it works fine, but between showers it wants to get "stuck" and the water pressure isn't enough to open this thing until I mess with it (which is the last thing I want to do every morning). There is no shortcut, if you want a shower that both flows and doesn't suck, install a p-trap. If you can't, you are screwed. All these "flaps" suck and dont work as promised. Highly disappointing.

Used chicken scissors to cut the flange trim. Very easy. Can work as a standalone drain cover. Comes with glue if you want to glue the flange (we opted not to glue it). Insteat, we to placeed underneath the legacy metal drain cover that screws down. Fits flush beneath the old drain cover. The main unit is threaded and comes with an attached "handle" to unscrew from the flange. Easily manages the volume of one valve, but will struggle slightly if you have a two-valve shower system (because there will be twice the water flow). Our two valve shower has a sunken 4" pan - and when both water valves are open, water will accumulate about 1/2" deep - but drains very fast once we turn off one valve, even though the other valve is still running. We view this as a positve as it allowes fresh water to accumulate in the corners of our 6'x3' shower (will save us cleaning time). System uses a magnet to close the valve when not in use. Weight of water will open the valve. Very pleased.

If you have a good water pressure, the water drains very slow and pools up. It works better with showers that have low pressure.

I had flies and a very stinky smell that was worse when I took a shower, so bad we didn't use the connecting bedroom, tried everything except pumping the septic tank, this was easy to install, and I would buy this again in a heartbeat. Did I mention this thing is awesome, sleeping good now, have awesome non stinky showers too, no smell yessssssss

Just recently installed so can't attest to the longevity of the item. But it works exactly as it should. We are using it on a drain with minimal water going down it. I have not noticed any water building up so seems the mechanism works. But more importantly it is working to prevent odor and backflow of water. Would recommend.

This has been a game-changer in stopping back water flow in my bathrooms and kitchen from overflowing sewers. Highly recommend. Seven stars

Best system need to put in all apartments in Dubai. But price very high must be cost 40

A neat little unit but does need to be trimmed and in my case I had to use a dremel tool to shape the flange to fit the smaller PVC pipe that was installed in the shower floor. Nicely prevents sewer gas from coming up through the drain and should prevent back flow of water as well. The prices for similar units vary from about 30-70 bucks, but this one works fine.

Easy to install, the water does drain a bit slower. I bought it for two reasons, one to prevent back flow, the other is prevent radon gas from entering. Very happy with the product.
