If you notice any of these signs, call a professional now before the leaking drain pipe turns into something else far worse. 1. Sewer Odor. If you begin to smell a foul odor near a wall, a drain pipe may be leaking. Your home drain pipes are designed to be airtight, allowing waste to move through your home unnoticed by your eyes or nose.
Just turn the valve on the P-trap counter-clockwise until water spills out. 2. Unscrew the slipnuts starting from the drain to remove the pipe. The slipnuts are the round connectors between 2 pipes. Start with the slip nut where your sink drain connects to the long vertical pipe underneath your sink.
Tighten the hoses hand tight, then one quarter turn with slip joint pliers or pipe wrench. Once the hoses are installed, turn HOT and COLD water on. Check for water leaks on both ends of the hoses. If no leaks are found, turn the power back on to the washer. Run a test wash and observe the water hoses for any leaks. My galvanized kitchen sink drain pipe is in a plaster wall behind a wood cabinet. The stub coming out of the wall into the cabinet is corroded (right at the wall) and the bottom of the stub (that I can feel in cabinet) seems like it is gone. It is leaking in basement directly under the stub.
