Repair defective drain from washer and kitchen Dispatched to clients home to diagnose drainage issues from laundry room backing up into kitchen sink. I entered the crawlspace and inspected the grade on the drain from the kitchen basin and found it to be severely back graded. In order to address this issue, I created an estimate to raise the kitchen drain configuration so that proper grade can be achieved. I cut and rebuilt the 2 inch PVC drain using a 45, 90, and some additional 2 inch pipe. I then tied into the existing drain using a 2 inch PVC coupling. When finished, I allowed my glue to cure fully, inserted the cold line from the washing machine into the washing machine drain, ran it wide-open, and also ran the kitchen faucet at the same time. There is no longer a back up into the kitchen sink from the laundry. Drain and proper grade on the drain have been created. See company cam for details on my work.
