If the P-trap was clear, the blockage is further down the line. With the P-trap removed, insert the end of a drain snake (or auger) into the drainpipe that goes into the wall (the trap arm). Push the snake into the pipe until you feel resistance. Lock the cable in place and slowly turn the crank clockwise. This rotational motion will either break up the clog or allow the corkscrew tip to grab onto it. Continue to push forward and rotate. If you grab the clog, pull the snake back out slowly, cleaning the cable with a rag as you go. Repeat until the pipe is clear.
You're viewing a step from: How to Clear a Grease-Clogged Kitchen Drain
A comprehensive guide to clearing a kitchen sink drain clogged with grease. This process starts with simple home remedies like boiling water and a baking soda/vinegar solution, then progresses to more involved mechanical methods such as using a plunger, manually cleaning the P-trap, and finally employing a drain snake for deeper blockages. The instructions are tailored for a completely blocked double kitchen sink with a garbage disposal.
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 Once withdrawn, run water through the drain for a few minutes to confirm proper flow and flush away any remaining debris.
