Replacing a bathroom sink drain plug means matching the stopper type first, then swapping the drain body and reconnecting the linkage under the sink.
Push-button or toe-touch stoppers skip the linkage and follow a different path. Match the style before you buy.
Which Stopper Type Do You Have?
Identify it in under a minute without removing a part. Look inside the drain and under the sink: a pop-up has a flat or domed stopper that rises when you pull a rod behind the faucet, plus a horizontal pivot rod entering the tailpiece. Push-button (click-clack) stoppers pop up when pressed and never connect to a rod. Toe-touch stoppers lift and drop with a tap, no linkage. Universal inserts are rubber or silicone plugs that drop into an existing opening.
- Pop-up: lift rod behind the faucet, pivot rod under the sink, clevis strap connecting the two.
- Push-button (click-clack): press to open, press to close, no rod.
- Toe-touch: tap the stopper, spring-loaded, no rod.
- Universal insert: drops into an existing drain opening.
Only the pop-up uses the full linkage sequence below. Push-button, toe-touch, and inserts come out by hand or a quarter turn and install the same way. Sizing matters: an insert must match the drain opening’s inner diameter, and a replacement drain body must match the existing style and opening size.
Replacing A Pop-Up Drain Plug: The Step Order That Works
Disconnect the linkage, remove the old stopper and drain body, clean the opening, install the new body with fresh sealant, reconnect, then test.
- Empty the cabinet and set a bucket under the P-trap; water will spill when you break connections.
- Loosen the nut on the pivot rod and slide it out of the tailpiece. Note how the clevis strap, washers, and grommets sit before anything comes apart.
- Lift the stopper out from above. If it won’t clear, loosen the drain body locknut underneath and drop the old assembly out.
- Scrape old plumber’s putty or silicone off the drain opening with a plastic scraper. A clean mating surface stops the next leak.
- Install the replacement flange and drain body with the manufacturer’s specified sealant. On granite composite or stone sinks, use silicone instead of putty — putty can stain those surfaces.
- Reconnect the pivot rod, clevis, and lift rod in reverse order, then reinstall the P-trap.
- Run hot water and work the lift rod through its full travel. Watch the strainer nut, assembly threads, tailpiece joint, and trap nuts for drips.
Take your old stopper or its measurements to the store. Danco’s pop-up stopper line organizes replacements by style and size.
| Stopper Style | Linkage Under Sink | Removal Method |
|---|---|---|
| Pop-up | Pivot rod, clevis, lift rod | Disconnect rod, lift stopper out |
| Push-button (click-clack) | None | Unscrew or pull straight up |
| Toe-touch | None | Unscrew the retaining nut by hand |
| Universal insert | None | Pull the old plug out of the opening |
| Grid strainer | None (fixed) | Replace the whole drain body |
| Lift-and-turn | None | Twist and lift out |
| Flip-it style | None | Unthread the post from the drain |
What Goes Wrong Most Often
Most failed replacements trace back to reassembly order or force.
Washers and grommets only seal in one orientation — lay them out in a row as you remove them, or photograph the assembly first. Over-tightening the threaded shaft or retaining nut cracks seals and binds the mechanism; snug, not cranked down. Skipping cleaning leaves old putty ridges that hold the new body off the sink surface and leak.
Verify travel before you finish: the stopper should seat fully closed with water standing in the bowl and rise fully open so the bowl drains fast.

Frequently Asked Questions
Do I need to remove the P-trap to change a drain plug?
Not always. Many pop-up stoppers lift straight out from above once you disconnect the pivot rod underneath, leaving the trap untouched. You only need to drop the trap when the stopper won’t clear the opening or when replacing the entire drain body and flange. Keep a bucket underneath either way — trapped water will spill once you break a connection.
Why won’t my new stopper close all the way?
The pivot rod is usually set at the wrong depth in the clevis strap. Loosen the nut on the clevis, slide the rod in or out a fraction of an inch, and retest.
Can I use plumber’s putty on any sink?
No. Putty is standard on porcelain and stainless steel, but it can stain granite composite and natural stone, so manufacturers specify silicone sealant for those surfaces. Check your sink material first — the wrong choice leaves a permanent mark around the drain opening.
