Customer had a slow draining tub. Noted to customer age and condition of the waste and overflow for the tub, as well as cast pipe going into the crawlspace. Recommended replacing the waste and overflow as a first step. Replaced the waste and overflow as the first step and tested the tub. Drain is still slow. Recommended replacing the rest of the 2 inch to the crawlspace as the next step to get the drain working. Customer wasn’t able to commit to replacing the line right now, customer requested replacing the two turns on 45s before the vertical pipe to see, completed the cast repair. Tested work and drain was still backing up but took awhile. The next step is to replace the cast line into the crawlspace. Left quotes to perform that work, as well as two other options for replacing cast that had rust marks all the way to the kitchen where the drain line is rusting and closing back up, as well as a proactive price to replace the kitchen line and laundry line.
