Thank you. **Q: Ive took a measurement but will this fit inside an 1&1/2 abs pipe.39.5 millimeter is 1.555 inches is that to tight?** A: It’s made for 39 to 43 and that’s because they send additional gaskets to fit on to make it fit to the 43. It should fit the 39.5 snug. **Q: Does this fit inside of a standard 2" floor drain pipe?** A: No, this floor drain max can allow 1.7in diameter. Thank you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solved my problem flows well and prevent back up *by B***L on July 15, 2020* Well the little bugger works! I had to get a good sized washer to close in the gap but after that I no longer have water backing up the basement shower drain! Whew! And water flows DOWN this easily so no one stands in a puddle. Works great ### ⭐⭐⭐ Good Design, Strange Size *by S***. on June 23, 2020* It's a smart design to prevent backflow, but the sizing is weird (something like 1.79 inches wide?) which I've never seen a drain pipe in that size. Make it in 2, 3, or 4 inches and it's an easy 5 star. ### ⭐⭐⭐⭐ Odor Free! *by D***R on January 12, 2021* Purchased 2 and seems it did the trick.
