I am considering adding a softener drain to my main drain in the basement. What are the design specifications for this?
- 2 inch vs. 1.5 inch
- does the entire trap have to be above the main 3 inch drain.
- how high does the vertical pipe have to extend above the trap......this is my major concern because I have limited space to the subfloor above. 17" from top of 3 inch drain to subfloor.
- location in regards to the vent? okay to be before the vent on the 3 inch line.
Thanks
