Came out for a clogged laundry drain. Arrived and found washing machine drain was a 1.5” pvc drain shoved inside a 2” cast iron pipe going down into the slab. Cast iron was backing up and not draining. Cast iron did not go into the crawlspace. It ran underground and tied into the cast iron mainline somewhere under the deck before connecting to the septic tank. Customer elected to have us install a pump basin next to the washing machine and reroute the drain through the crawlspace and tie into a section of the cast iron. Cut out section of cast iron and installed a pvc tie in. Ran 2” pvc back into the laundry room. Installed pump basin and check valve. Ran new vent out side of house. Stuck garden hose down sat pipe and tested basin through 10 cycles and inspected to ensure proper function and a leak free installation. No further issue at this time. 2 year labor warranty on the piping, 1 year warranty on the pump basin. Thank you for choosing Chen Plumbing!
