In this video

To begin, place a bucket or container directly under the sink's P-trap assembly to catch any water or debris that will spill out during disassembly. Then, wearing gloves, use your hands to loosen and unscrew the slip nuts connecting the P-trap to the sink's tailpiece and the drain pipe in the wall. Carefully remove the P-trap sections and place them in the bucket.

Goal: Remove P-trap

  • Wear protective gloves, as the trapped water and debris can be unsanitary.
  • If the plastic slip nuts are too tight to loosen by hand, you can use channel-lock pliers, but apply gentle pressure to avoid cracking them.

FAQs

Why is disconnecting power to the garbage disposal the first step, and how do I do it safely?

Disconnecting power is crucial to prevent accidental activation and serious injury while working inside or near the disposal blades. Locate your home's main electrical panel and switch off the circuit breaker labeled for the kitchen or disposal. If the circuit isn't clearly marked, you can unplug the unit directly from the wall outlet if it's accessible under the sink.

What if the garbage disposal hums but doesn't spin, and what's the first thing I should check?

A humming disposal indicates power but a jam, likely from a hard object lodged between the impellers and the grinding plate. After ensuring the power is OFF, visually inspect the disposal chamber with a flashlight for foreign objects. Then, use an Allen wrench in the hexagonal hole at the bottom center of the disposal to manually turn the motor shaft and free the impellers.

Do I really need all the specialized tools listed, like the Channellock pliers or socket wrench set, for this project?

While a sturdy plunger is essential, tools like Channellock pliers are highly recommended for securely gripping and loosening slip nuts on the P-trap without damaging them. A socket wrench set can be useful for more stubborn connections, especially on metal P-traps, making the job much easier and preventing stripped parts. Having the right tools minimizes frustration and potential damage.

How do I effectively plunge a double kitchen sink when one side is clogged and the other is clear?

To effectively plunge a double sink, you must create a seal on the non-clogged basin to prevent water and pressure from escaping. Use a stopper, a wet rag, or even a helper to hold down a stopper firmly in the non-clogged side. This directs all the plunging pressure towards the blockage in the clogged basin.

Let's fix this slow draining sink by cleaning out the drain. This sink and the customer's primary bathroom was slowly draining. They wanted to get that fixed before it became a major issue. That clear tube connecting to this drain is the AC compensation drain. In my area it is pretty common for them to connect them to the sink drains like this but it does cause issues over time. Inside the AC pan you can have bacteria and as that bacteria goes through the drain line you get
