How to Clean Out a Bathroom Sink P-Trap · Step 1 of 8
This guide provides verbose step-by-step instructions for removing, cleaning, and reinstalling a bathroom sink P-trap to clear a clog and restore proper drainage. The process involves preparing the under-sink area, carefully unscrewing the trap to catch water and debris in a bucket, scrubbing the trap clean, and then reassembling the components, finishing with a thorough leak test.

FAQs
What safety precautions should I take beyond just wearing gloves?
Always wear heavy-duty latex or work gloves to protect your hands from dirty water, grime, and potential cleaning agents. Also, ensure good ventilation in the bathroom, and have plenty of old rags or paper towels (Scott 75260) on hand for immediate cleanup of any spills under the sink.
Do I really need specialized pliers like Channellock, or can I use a regular wrench?
While a regular adjustable wrench might work, Channellock tongue and groove pliers (430 or 440) are highly recommended. They provide a superior grip on the plastic slip nuts without damaging them, making loosening and tightening much easier and reducing the risk of cracking the pipe components. These pliers adapt better to various sizes and odd angles under the sink.
What's the most common mistake people make when cleaning a P-trap, and how can I avoid leaks after reassembly?
The most common mistake is overtightening the slip nuts during reassembly, which can crack plastic pipes or deform the rubber washers, leading to leaks. To avoid this, hand-tighten the nuts until snug, then use pliers to give them an additional quarter to half a turn, ensuring they are firm but not strained. If a leak persists, ensure the Oatey slip-joint washers (HDC2699C) are correctly seated and not damaged, replacing them if necessary.
Can I use chemical drain cleaners instead of manually cleaning the P-trap?
While chemical cleaners might offer a temporary fix for very minor clogs, they often don't fully remove accumulated hair and solidified grime common in P-traps. Furthermore, they can be corrosive to pipes and pose health risks. Manually cleaning the P-trap, as detailed in this project, is a more effective, safer, and long-lasting solution for blockages at this specific location.
