Bill H. I preformed a pipe repair on the galvanized steel drain line in the upstairs hall bathroom.on year warranty on the repair. I also replaced the trap in the same bathroom. Two year warranty on the trap install. I also had to clear a stoppage in the same lavy drain. I ran my cable about 21 feet down the line. Stoppage is clear. No warranty on the stoppage. I recommend the customer use the bio clean to maintain the drain.
