The LORDAHL BCK-01 is a ballcock-style toilet fill valve designed for residential and light commercial toilet tank applications. A ballcock controls the refill cycle of a toilet tank by opening to admit water after a flush and closing once the tank reaches the correct water level. The BCK-01 delivers reliable shutoff performance in standard toilet tank installations and is suited for replacement or new-installation work carried out by licensed plumbers or experienced DIYers.
The BCK-01 is intended for use in toilet tank assemblies where a ballcock-style fill valve is specified. It fits into standard toilet tank configurations found in residential bathrooms and light commercial restroom facilities. This type of valve is a common service item replaced during routine toilet repair calls or full tank rebuild jobs.
Designed as an OEM-style replacement for standard ballcock toilet fill valve applications in residential and light commercial toilet tanks.
Installation of toilet fill valves is typically performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Before servicing, shut off the water supply valve at the base of the toilet and flush to drain the tank. Disconnect the water supply line before removing the existing fill valve. Verify tank dimensions and shank length compatibility before completing the installation.
