I am going to install a shower in my basement over an existing floor drain.

What is the preferred method of connecting the shower drain to the floor drain? The drains may or may not line up. I am planning on buying one of those one-piece shower stalls from a big-box store.

Also, is there some type of device I can install in the floor drain to keep sewage from backing up into the shower in case I have a septic tank problem?

Thanks!!

Hey Steve,
You ask,"What is the preferred method of connecting the shower drain to the floor drain? the drains may or may not line up. "
Before I can answer your questions I have to know the exact location of the shower base drain in relation to the center of the floor drain, also the type of the drain and the material the drain is made of and will have to hook up to. Regards, tom
