Completely blocked drains need more than a plunger can provide. The Richlands homeowner had already tried clearing the kitchen sink without success. Our plumber checked the trap and found the blockage sat further along in the waste line. Sometimes what looks like a simple sink blockage turns out to be buildup in the branch drain or even the main line. S&J Plumbing and Gasfitting cleared the obstruction and tested both basins to confirm proper flow. Blocked drain repair in kitchens often reveals grease accumulation that builds up over time. The sink now drains quickly again. Call now if your kitchen sink is completely blocked.
