Customer agreed to drain and water line install. Upon arrival we started with the cast iron drain tie in. We used a ratchet cutter to sever the 3” pipe enough to fit a 3x2 San tee. Used a transistion band to transfer to 2” PVC. Installed a 2” P trap for drain as well. We also cut in a 3/4x1/2” water line from the shower line in the unit behind the wall. We ran 1/2 line and stubbed out with shark bite. Also supplied support for ptrap in wall. Tested drain multiple times and turned water back on. No leaks. Customer satisfied.
