Pride Plumbing was called out for a clogged bathroom sink drain line. We removed the sink's P-trap and extension and tried using a sewer machine, but it couldn't make the turn down into the drain. Then we climbed up on the roof and ran a sewer tape down the sink's roof vent and cleared the blockage. We provided a cost estimate to replace the bathroom sink's P-trap, drain 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.
