How to Clean Out a Bathroom Sink P-Trap · Step 6 of 6
In this video
Begin reassembly by dropping the clean pop-up stopper back into the sink drain. From underneath, re-insert the pivot rod, making sure it goes through the loop on the bottom of the stopper. Hand-tighten the retaining nut. Reconnect the lift rod to the pivot rod with the clip. Re-install the P-trap, ensuring the gaskets are in place and hand-tightening both slip nuts. Remove the paper towel from the wall pipe. Finally, turn on the faucet and run water to test that the drain is flowing freely and to check for any leaks at the connections you just tightened.
Goal: Reassemble the drain and verify the repair.
- When re-inserting the pop-up stopper, make sure the hole at the bottom faces the back of the sink so the pivot rod can pass through it.
- Check carefully for leaks at all connections after turning the water back on.

FAQs
What essential safety gear should I use when cleaning a bathroom sink P-trap?
Always wear safety gloves and eye protection to shield yourself from dirty water, potential splashes of grime, and any old cleaning agents that might still be present. This project can be messy, so protecting your hands and eyes is crucial for hygiene and safety.
How long does this P-trap cleaning project typically take for a beginner, and what's the approximate cost?
This project is rated for beginners and typically takes about 90 minutes. The cost is minimal if you already own basic tools like pliers and a bucket; you might only need to purchase new slip nuts and washers if the old ones are worn, which are inexpensive.
Do I need specialized plumbing tools for this, or can I use basic household items?
While basic items like a bucket and towels are essential, you will need specific tools such as Channellock Tongue and Groove Pliers to loosen the slip nuts effectively. A flexible bottle brush is also highly recommended for thoroughly cleaning out debris inside the P-trap.
What are common mistakes to avoid during reassembly to prevent leaks after cleaning the P-trap?
The most common mistakes are misaligning the flanged washers or overtightening/undertightening the slip nuts. Ensure the washers are correctly seated, hand-tighten the slip nuts first, then use pliers for a final snug turn without stripping the threads. Always run water and test for leaks immediately afterward.
