I have to extend a 1" drain pipe so it will reach the floor but don't want to dig up my floor.
I was looking for a coupler with a female end to connect the pipe and a male end so I can screwn in a sealing washer and a locknut. I looked everywhere but can't seem to find a coupler to do this. Does anyone know if these exists?

Why would you have to dig up your floor to extend the pipe? Go in to any plumbing or hardware store and ask for a PVC 1" male slip to thread adapter, (see image). Don't forget the glue and primer. Good luck, Tom
