Brass Push Pop-Up Drain

The Kingston Brass KB8108 is a solid brass bathroom sink drain with a push pop-up mechanism and overflow port. It suits homeowners and plumbers fitting standard bathroom basins who want a durable, matching finish. The spring-loaded design lets users open and close the drain with a simple press. This new item carries California Proposition 65 warnings for cancer and reproductive harm.

Spring Mechanism Installation

The push pop-up drain installs into a standard sink opening using the supplied brass body and overflow connection. Tighten the locknut by hand then give a quarter turn with pliers; over-tightening can crack the basin or strip the threads. The spring cartridge seats with a click — if it binds, remove debris from the seat before forcing it. No special tools are required beyond an adjustable wrench.

Basin Compatibility Check

Verify that your sink has an overflow hole aligned with the drain outlet; this model will not seal on vessels without overflow. Measure the drain hole diameter to confirm it matches standard sizing before ordering. Ensure the chosen finish coordinates with existing faucet hardware for a consistent look. The Proposition 65 notice applies to the brass alloy used in this fitting.

Questions about this item

How can I verify the push pop-up drain is operating correctly after installation?

After fitting the drain, run water into the sink and press the brass cap; the spring mechanism should close the opening firmly and pop it open again with a second press, confirming the overflow path remains clear.

What components are included with the KB8108 drain and what must be purchased separately?

The package supplies the brass push pop-up drain body with overflow holes and the matching finish cap; supply lines, plumber's putty or silicone sealant, and any required tailpiece extensions are not included.

Which finish option should I select to coordinate with my faucet?

Choose the finish — such as polished brass, brushed nickel or oil-rubbed bronze — that matches your existing faucet trim, as the drain is offered in multiple Made To Match finishes for a uniform look.
