Project

If the P-trap was not the source of the clog, the blockage is further down the drain line. Take your drain snake (or drain auger) and insert the auger end into the drain arm pipe that leads into the wall. Push the snake cable into the pipe until you feel resistance. Once you hit the clog, lock the cable clamp and begin turning the handle clockwise while applying gentle forward pressure. This will either break up the clog or allow the auger to hook onto it. You may need to push and pull the cable a few times. If you feel the snake has hooked the clog, pull it back out of the pipe slowly, bringing the debris with it. Clean the auger tip and repeat if necessary.

Frequently Asked Questions

Do I need to buy all the specialized tools, especially the drum auger, to unclog my double kitchen sink?

Not necessarily for every clog. Start with simpler tools like the HDX Sink and Drain Plunger. If that doesn't work, cleaning the P-trap requires basic pliers and a bucket. The Plumber's Choice 25 ft. Drum Auger is only needed for deeper, more stubborn clogs further down the drain line.

What are the most critical safety precautions I should take, especially since my double sink has a garbage disposal?

The absolute most critical step is to always disconnect power to the garbage disposal at the circuit breaker before performing any work near or inside the drain, even if you're working on the non-disposal side. Additionally, wear Heavy Duty Latex Gloves to protect your hands from grime and potential drain cleaner residue if any was previously used.

How long should a beginner expect this project to take, and is it genuinely a 'beginner' difficulty project?

For a simple clog cleared with a plunger, it might take 15-30 minutes. If you need to clean the P-trap, allocate 1-2 hours for setup, cleaning, and reassembly. Snaking a deeper clog can extend the project to 2-3 hours for a beginner. It's beginner-friendly in terms of steps, but patience and attention to detail are key.

When I try to plunge one side of my double sink, water just backs up into the other basin. How can I fix this?

This is a very common issue with double sinks due to shared drainage. To create effective suction with the plunger, you must completely seal off the drain opening of the non-clogged sink. Use a Universal Sink Stopper or have a helper firmly press a wet rag over the opening while you plunge the affected side.
