Slowly turn the hot and cold water supply valves under the sink back on by turning them counter-clockwise. With the water on, check for any drips or leaks around the faucet base and handle. If there are no leaks, proceed to the final step. If leaks are present, you may need to use a special wrench to slightly tighten the adjustment ring inside the retainer nut.

FAQs

What tools and materials do I absolutely need for this project, and are there any common household items that can substitute?

You'll primarily need Channellock pliers, a bucket, and a brush. A towel is also crucial for managing spills. While specific plumbing washers are listed, you might have a similar brush for cleaning, but proper pliers and a bucket are essential. Do not substitute specific plumbing washers.

Are there any important safety precautions or warnings I should consider before I start cleaning my P-trap?

Always turn off the water supply to the sink before starting to prevent unexpected water flow. Wear gloves to protect your hands from grime, bacteria, and any cleaning solutions you might use. Have plenty of towels on hand for spills, and work in a well-ventilated area if using strong cleaning agents.

This project is labeled 'beginner' and estimated at '90 minutes.' Is that realistic for someone with limited plumbing experience?

Yes, this is a very beginner-friendly project, and the 90-minute estimate is generally realistic. It accounts for gathering tools, disassembling, cleaning, and reassembling. If you encounter seized nuts or need to replace old, brittle washers (like the Oatey rubber washers), it might take a bit longer.

My sink still leaks after I reinstalled the P-trap. What's the most common reason for this, and how can I fix it?

The most common reason for leaks after reinstallation is improperly seated or worn-out slip-joint washers. Disassemble the connections, check that the rubber washers (such as Oatey 1-1/2 in. rubber washers) are correctly oriented, not cracked, and properly seated within the slip nuts. Hand-tighten nuts first, then give them a final snug quarter-turn with your Channellock pliers.
