Painting a concrete basement floor
There is no floor drain or open sewer line/vent. In fact the sewer line
from upstairs goes out to the outside at the ceiling level of the
basement.
You say that both the HW tank and HVAC air handler are in the basement.
What provision was made for the HW tank leaking and the condensate "drip"
from the AC. Surely there is some sort of drain there ?
