    Good Possible Idea but....
  

*by F***N on Reviewed in the United States on December 13, 2018*

This sounds like a great option for my houses old drains/plumbing. Many of my drains do not have traps and sewer gases/insects have a portal to my house using the path from the drains. I've been using standard rubber plugs for years but, was hoping these gadgets would solve the remove-replace plug process when you need to use the drain. The rubber sleeves fit snuggly in the drain and the metal covers loosely fit over the top but, don't stay in place very well. This is not that big of a problem. The real problem is: I put one in my shower drain plug and unfortunately the water starts to build up in the bottom of the shower because the rubber sleeve does not  open it's little rubber baffle very well, so draining is slow. I do not like this because when your shower fills up with water it traps soap scum and misc. people pieces and causes rings, grime, mildew, etc. I tried to modify the little rubber baffle sleeves by carefully cutting with a pair of scissors but could not find the magic/perfect cut that would allow better drainage yet keep bugs and odors away. I will keep the remaining three (I cut up one and received four) in case I find a use for the  rubber sleeve/baffle. I'm sure there is some possible use for this for an RV, make-shift temporary tub/pool, etc.

    This will not work for a shower or any drain that requires 2 GPM or more
  

*by D***K on Reviewed in the United States on September 29, 2018*

I bought this for my shower  to prevent a odor that comes from the drain. The inner diameter of the pipe is 2" and this is supposed to be 1.97" (the metal insert is larger).  Calculating everything out it should have fit fairly snug.  After it arrived I found that the dimensions were actually smaller so it was fairly loose in the pipe. I figure I could engineer something for a tighter fit and did (silicone). My shower head is 2.5 GPM and the shower began immediately filling up. This  Backflow Preventer has no practical use in the home unless its being used with a very low volume of water. I am assuming this was originally made for a pipe with an inner diameter of 50mm.

    Worked OK
  

*by J***0 on Reviewed in the United States on September 26, 2018*

This item will work provided you have a long down tube in the drain. It installed nicely in the shower, but the tub had a short down tube and then a quick right angle, so I could not get it to work in the tub.
