The BSC PREFERRED DIB820-70 is a bathroom sink pop-up drain assembly with a plastic body and a polished brass plated rim. It is designed for use in bathroom sinks that include an overflow port. The assembly ships complete with a lift rod, plunger, and linkage, so a separate drain kit is not required. The inlet and outlet both measure 1-1/4 inches, matching standard lavatory drain sizing. This drain is installed by licensed plumbers or experienced DIYers during new sink installations or drain replacements.
The DIB820-70 fits standard residential bathroom lavatories equipped with an overflow. The 1-1/4 inch inlet and outlet dimensions align with common sink drain rough-in requirements, making it a straightforward drop-in replacement or new-installation component. The polished brass finish suits a wide range of bathroom fixture finishes. The complete linkage and lift rod included in the package reduce the need for additional parts on most standard sink configurations.
Designed as an OEM-style replacement or new-installation drain for residential bathroom lavatories equipped with an overflow and a standard 1-1/4 inch drain connection.
Installation is typically performed by a licensed plumber or qualified DIYer following local plumbing code requirements, including applicable IPC guidelines. Shut off the water supply and clear the P-trap area before beginning work. Connect the lift rod linkage to the pop-up stopper according to the sink manufacturer's configuration before tightening the drain body. Do not overtighten the locknut against the sink basin, as this can crack the plastic body.
