This valve will fit Sched 40 PVC or ABS (using special ABS/PVC transition cement). Connecting to anything else will have to use adapters. Always test before installing. Always bring a pipe sample when hunting adapters. Works great no leaks, unlike Canplas brand

    Installed a week ago after having to purchase a modad sewer drain - schedule 40 pvc coupling. The female connections on the valve are 4.5” ID and the sewer line is a little under 4-1/4” OD. The computer showed an inventory of 14 couplings in stock in a location that didn’t exist. I did find one.

    used this product to tie in gutter drainage to a sump pump system. Did not want the sump pump to push water back up the gutters in case of a stoppage somewhere in the line. It works perfectly, and has been for 5 years now.

      This was easy to install and appears to be higher quality and more root resistant than the one that came with the house when it was built with the house. I don't expect this one will ever need to be replaced.

      Solved a basement flooding issue
      Used this product to prevent rain drainage from drainage system under a building from backing up into a crawl space drain system that would then seep into basement. Product prevented water backup and flooding during two major rain events in Sept and Oct 2016 of over 7 inches per day including hurricane Matthew. Easy to install into the existing 4 inch PVC piping.

      Just what the doctor ordered, great product!!!
      I was having problem with toilet backing up occasionally when we would get too much rain for several days due to the waste system getting overloaded I guess. I knew about backflow prevention devices for potable water and wondered if there was such a device for sewer lines, I pulled up the home depot website and started to search for backflow devices and there it was.........a backwater valve............awesome...........just what I had been thinking I needed to stop my dirty mess cleanup jobs in the bathroom...............this is the ticket folks!!!

      great design, all access clean-outs should be designed like that one
      I have been using this cleanout for 3 years and got another one for my second house. Pros: LIght, durable, flap valve to prevent backflows, Easy to open / close cap, low profile. Smart level stepdown flow. Cons: Not sold at the stores. I think they should.
