I'm looking at a condo built in 1965. The building inspector found clean outs for kitchen and baths, but no main clean out. He says there might not be a main clean out for a building that old.
Is this true? If there is one, hidden somewhere, where would it be? Would the hoa know where the main drain runs?
Very common for a building not to have a main clean out plug---
As to the exact location of the sewer---if you ever need to know a plumber has a number of ways to find it--cameras--and locator balls that get flushed down the toilet and send signals to a sensor as the head to the street---Mike---
