Pride Plumbing came out and provided cost estimates to 1) unclog a slow-draining kitchen sink drain by either using a closet auger, sewer machine, or water pressure device; and 2) replace the kitchen sink's under-sink drain assembly, P-trap, and drain line through the floor to under the house in the crawlspace, and to where it ties into the main sewer drain stack, with new PVC piping and fittings.
