Pride Plumbing was called out for a clogged kitchen sink drain. We removed the sink’s P-trap and drain assembly and used a sewer machine down through the sink's drain line and pulled back grass. We then went outside and found a grey drain line exiting at the edge of the yard. We dug a ditch to assist the grey line in draining properly. After replacing the P-trap and drain assembly and testing for leaks and proper drainage, the issue was corrected. We ran hot water down the sink for several minutes and it drained properly. We also provided a cost estimate to replace the kitchen sink's under-sink drain, P-trap, and drain line through the floor to under the house in the crawlspace, with new PVC piping and fittings, and tie into the main drain stack.
