I have been doing my own plumbing for many years. The town was to pay for the rerouting of the sewer drainage in the basment.
I removed 25' of cast iron pipe Installed 40'pvc to two toilets 1 washer trap 1 sink 3 cleanouts all the hangers 8 4" elbows caped off the old line. The materials cost 300.00 and due to them forgetting to get it done and they couldn't get a plumber to do it that night and the old line was to be removed the next am leaving me with now sewer due to their screw up. I did it from 4 pm until 1:30 am and removed the old pipes in an additional
3.5 hrs
They said to send a bill I want to make sure I charge enough I was looking at $700 including materials but this may be too low I don't want to screw them yet I think it would have cost alot more Whats a fair cost for saving them Jon
