Slotted or unslotted — get this wrong and it leaks · review
A complete pop-up drain assembly for sinks with an overflow, with all gaskets and a one-year warranty.
Overall length 8 5/8 in. Cap 2 5/8 in. Tailpiece 1 1/4 in. Drain opening 1 3/4 in.
That is enough to check against your own sink and your own trap before ordering anything — which on a parts shelf is the entire question, and which the Kohler assembly on this shelf, at three times the price, does not provide at all.
For sinks WITHOUT overflow, please see KRAUS pop-drain model number PU-10.
That is the single most useful sentence on this shelf, and it is a company pointing you away from the product you are looking at.
Here is why it matters. Look at the back of your sink, below the faucet. If there is a small hole near the rim, the sink has an overflow — a channel molded in the ceramic running down to the outlet — and the drain body must be slotted so that water can get from the channel into the drain.
If there is no hole, the body must be solid.
Fit a slotted body to a sink with no overflow and it leaks into the cabinet, because the slots open into the underside of the ceramic.
Fit a solid body to a sink with one and the overflow cannot work, which you discover on the day somebody leaves the faucet running.
This is the with-overflow version. The Kohler on this shelf is the without-overflow version and says so. Four of the six listings here do not mention overflow at all.
Spring-loaded pop-up stopper does not require a lift rod.
Which removes the fiddliest part of fitting a traditional drain: the rod behind the faucet, the pivot through the back of the body, the clip, the strap, and the twenty minutes of adjustment in the dark to make the stopper seat.
A click-clack has none of it. You push the cap.
All rubber gaskets included — creates a perfect seal for standard-size drain openings.
Small, and the difference between finishing the job and driving to a merchant for a washer. The Kohler listing on this shelf does not mention gaskets.
The only warranty published among the parts on this shelf.
Spot-free stainless, which resists water spots and fingerprints — and which the listing says twice must not be cleaned with abrasive chemicals or cleaners.
That is how a spot-free finish stays spot-free, and it rules out the scouring cream most people keep under the sink.
Not when the cap is cracked, and not when the click-clack has stopped springing — the small parts on this shelf fix those for $8 to $10, and they sit above the ceramic.
This replaces the body that passes through the sink, the tailpiece down to the trap, the gaskets and the stopper.
So: a leak under the sink, a corroded tailpiece, or a new sink with nothing in it. For that job, this is the best-documented part on the shelf.

Look for a small hole near the top of the bowl, usually at the back, below the faucet. If it is there, your sink has an overflow — a channel molded into the ceramic running from that hole down to the outlet — and the drain body must be slotted so that water from the channel can get into the drain. If there is no hole, the sink has no overflow and the drain body must be solid. Fitting a slotted body to a sink without an overflow leaks into the cabinet, because the slots open into nothing but the underside of the ceramic. Fitting a solid body to a sink with one blocks the overflow, which you discover the day somebody leaves the faucet running. This assembly is the with-overflow version, and Kraus names PU-10 for the other case.
Because getting this wrong is the commonest mistake on this shelf and the hardest to diagnose from a photograph. Kraus publishes, in its own fifth bullet: "For sinks WITHOUT overflow, please see KRAUS pop-drain model number PU-10." That is a company pointing you away from the product you are looking at, which no other listing here does. The Kohler assembly on this shelf is without overflow and simply states it — correct, but it leaves you to find the with-overflow version yourself. Four of the six listings on this shelf do not mention overflow at all.
Only if the body is the problem. The small parts on this shelf replace the cap or the mechanism, both of which sit above the ceramic. This replaces the whole thing: the body that passes through the sink, the tailpiece that goes down to the trap, the gaskets that seal it, and the stopper. So the question is what has failed. A worn or broken click-clack: buy a $7.79 bolt. A pitted cap: buy a $9.66 pack of caps. A drain that leaks under the sink, or a corroded tailpiece, or a new sink with nothing in it: buy this — and the published dimensions and the included gaskets are what make it a one-trip job rather than three.
Same category, nearby prices, between bathroom fittings. What remains is the specifications every one publishes — half empty, a column is no use.

| Kraus PU-11 pop-up drain with overflow | $35 | A 1 1/4 IN TAILPIECE CONNECTION, suiting a 1 3/4 in drain opening with standard US plumbing — A COMPLETE ASSEMBLY: body, tailpiece and stopper, with all rubber gaskets included. Cap diameter 2 5/8 in, about 2.63 in (66.7 mm). Stated for Kraus sink and undermount sinks, including the Elavo Ceramic series. | SLOTTED — for sinks WITH overflow, and the maker NAMES MODEL PU-10 for sinks without. It is the only listing on this shelf that tells you where to go if you bought the wrong one. | Spring-loaded, WITH NO LIFT ROD REQUIRED. | 8 5/8 in overall, from the pop-up top to the end of the tailpiece — the only full length published on this shelf, and the figure that decides whether the trap still fits beneath. |
| ALI2 click-clack pop-up bolts, 2-pack | $10 | M8 at the top, M16 × 1.5 at the bottom — the same two threads as the UXELY bolt on this shelf. THE BOLT AND SPRING MECHANISM ONLY, cap not included. Two pieces at $5.00 each. | SUITED TO OVERFLOW SINKS, per the maker — which is the slotted case, and the only statement of it on this shelf among the bolt-only parts. | Push to close and seal, push again to open and drain. The maker states it collects hair neatly and prevents it clogging. | 1.10 in (28 mm) CLOSED, AND NOTHING ELSE: the popped-up height is not published, where UXELY gives 1.52 in (38.5 mm), and neither is the overall height, where UXELY gives 2.30 in (58.3 mm). So the travel — the whole point of a spring bolt — cannot be worked out from this listing. |
| FASTROHY click-clack drain plug tops | $10 | An 0.31 in (8 mm) screw hole, which is the M8 standard on this shelf — THE VISIBLE CAP ONLY, with NO MECHANISM INSIDE and no bolt included. Two pieces at $4.83 each. The diameter is published TWO WAYS: 2.60 in (66 mm) in the title and 2.56 in (65 mm) in the bullets. The maker's own advice is to measure your size before choosing. Five published bullets, two of which repeat each other. | NOT PUBLISHED, and neither is the DRAIN HOLE SIZE IT SUITS, where Tong Gu on this shelf publishes 1.42 to 1.50 in (36–38 mm) — so nothing on this listing tells you whether it will seat in your drain. | NONE — it is a cap, pushed by whatever bolt you already have. | NOT PUBLISHED BY THE MAKER. |
| Tong Gu brass pop-up plug cap | $8 | A nominal 1/3 in (8 mm) screw — the M8 standard — stated to fit a standard M8 pop up plug bolt. THE VISIBLE CAP ONLY, and the maker states explicitly that THE BOLT IS NOT INCLUDED. One piece at $7.99 on October 29, 2026, against $4.83 each for the zinc alloy pair on this shelf. 2.6 in / 66 mm diameter, 2.60 × 2.60 × 2.60 in (66 × 66 × 66 mm). | NOT PUBLISHED as such, but it is the ONLY PART ON THIS SHELF THAT PUBLISHES THE DRAIN HOLE IT SUITS: 1.4 to 1.5 in / 1.42 to 1.50 in (36 to 38 mm). That one figure is what the other cap here leaves you to guess. | NONE — it is a cap, driven by the bolt you supply. | NOT PUBLISHED BY THE MAKER. |
