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 specific tools are essential for this pop-up drain adjustment, and why are so many types of towels mentioned?

You'll primarily need a screwdriver (Phillips or flathead, matching your clevis screw) and a bucket to catch any drips. The various towels are listed for cleaning, protecting your cabinet, and absorbing spills, but any absorbent cloth you have on hand will work perfectly for this beginner-friendly project.

How long should I expect this project to take, and is it truly suitable for a beginner DIYer?

This project is very beginner-friendly and typically takes only 15-30 minutes once you've identified the components. It's a quick fix that doesn't require extensive plumbing knowledge or special tools, making it an excellent starting point for home improvement.

After adjusting, my stopper still leaks or won't fully open/close. What should I troubleshoot next?

First, remove and thoroughly clean the stopper and the drain opening to eliminate debris. Then, double-check that the pivot rod and clevis strap are securely connected and not binding. Make small, precise adjustments to the clevis screw, testing after each increment, as over-tightening or incorrect positioning can cause issues.

Are there any important safety precautions I should take before working under the sink?

While this adjustment doesn't usually involve disconnecting water lines, it's wise to have a bucket handy for unexpected drips. Ensure you have adequate lighting under the sink to clearly see the components. Be cautious of sharp edges or tight spaces to avoid minor injuries.

through, that's nasty. So that's why it was clogged. I don't even know what that was. So all we need to do now is just go put everything back together and we should be good to go.
