I just found out that my house is the lowest one on our particular sewer line going to the main line. That means if the line gets plugged (like it did last Friday) between here and the main, sewage backs up into my basement first! Is there a reliable valve I could install in my 3" PVC basement drain to allow drainage of my A coil and water conditioner without allowing sewage to back into my basement? There's at least a 6" drop to the top of the water in the trap.
Edit: This IS the floor drain I'm referencing and the A coil and water conditioner drain into that at floor level. The only other drain in the basement is a slop sink, and that's 2.5' off the floor, so I'm not concerned about that. If the sewage gets that high, I'm toast, anyway.
