With the P-trap removed, you have direct access to the drain line entering the wall (the trap arm). If you suspect the clog is further down, this is your chance to clear it. Insert the head of a small drain snake (or hand auger) into the pipe. Push the cable in until you feel resistance, which is likely the clog. Tighten the locking screw on the auger's handle and begin turning the crank clockwise while applying gentle forward pressure. You'll feel the snake working its way through the grease. Once the resistance lessens, you have likely broken through. Retract the snake, wiping the cable with a rag as you pull it out to minimize mess.
You're viewing a step from: How to Clear a Grease-Clogged Kitchen Drain
This guide provides instructions to clear a grease-clogged kitchen drain using a combination of hot water, degreasing agents, and mechanical methods like removing and cleaning the P-trap and using a drain snake for deeper clogs.
Frequently Asked Questions
What's the best technique for working the cable 'back and forth' to clear the blockage effectively?
Apply steady, moderate pressure while slowly rotating the drum to allow the snake head to chew through the clog. Feel for resistance and gently pull back a few inches, then push forward again to break up the obstruction.
My drain snake cable stopped turning or feels stuck in the blockage; what's the next step?
This usually means the cable is bound. Squeeze and release the drain snake's trigger repeatedly while slowly turning the drum to free the cable and help it work through the stubborn part of the clog.
How can I avoid pushing the blockage deeper into the pipe instead of clearing it?
Focus on a 'drilling' or 'churning' motion by consistently working the cable back and forth with rotation. Avoid simply ramming the snake, as gentle, repeated action is more effective at breaking up the clog.
How will I know if the blockage has been successfully cleared during this step?
You'll feel significantly less resistance, and the cable should pass freely beyond the previous clog point. Once withdrawn, run water through the drain for a few minutes to confirm proper flow and flush away any remaining debris.
