Is this your part?
Look for a small overflow hole on the front rim inside the bowl. This drain has a side overflow port and only works on basins with that channel. Then measure the drain opening: it should be the standard 1-1/4 in. lavatory size.
When to replace it
The sink no longer holds water, the stopper will not lift or seat, the flange is corroded, the lock nut seeps at the flange seal, or a cracked pivot housing drips into the cabinet.

Questions
Will this fit a sink without an overflow hole?
No. The drain has a side overflow port and needs a basin with an overflow channel.
Will it fit a vessel sink?

Is it code-approved?
It is cUPC listed by IAPMO R&T to ASME A112.18.2 and CSA B125.2, and the cUPC mark is cast into the drain body so it can be checked on the installed part.
