Pride Plumbing came out and provided a cost estimate to 1) cut into and remove a section of asphalt just outside a boiler room over to a manhole; 2) dig down to and uncover the drainpipe underneath; 3) remove the clogged section of drainpipe; 4) replace the piping with either new stainless-steel or new Schedule 80 piping and fittings; and 5) replace the dirt we took out and fill in the hole.
