My house has an upstairs bath and nothing downstairs. i would like to
install a 2 pc bath in the laudry room off the kitchen. house is about
60 yrs old, has a foundation but no basement, and possibly a small
crawl space underneath (not sure). Soil stack is about 20-25 ft away
from laundry area. how do i go about tapping into this stack to add
drains and the like for a new bath? What is involved and should I just
call a plumber?
