Home (sometimes)handyman looking to install a pair of Toto EcoDrakes in a "back to back" setting. My house was built in the mid 1980's. It's a single story, slab foundation in Southern CA.
The documentation from Toto mentions that a Double Sanitary Tee/Sanitary Cross is not going to work and that it needs to be a Double Combination Wye.
Forgive my ignorance (I'm a homeowner, not a plumber), but I'm wondering how to tell what kind of drain connection I have?
