I have a City inspector who wants a "Static fill test of DWV (drain, waste and vent)", for an in-law unit
built in 1957, but never inspected. The pipes are galvanized and/or cast iron.
This is an a small in-law unit with a kitchen sink, vanity, toilet and shower. Everything goes to a single waste line under the slab then --- mysteriously somewhere --- must joint the main house system. There's no separate cleanout for the in-law unit.
How can the Static fill test be accomplished?
Would blocking the pipe at the City two way cleanout work, if both the main house and in-law were tested at once?
Any tips?
