The PASCO SPECIALTY MFG CO 1027 is a Douglas flush valve designed for toilet tank and flush system applications. A flush valve controls the release of water from the tank into the bowl during each flush cycle. This part is sold as a single unit and is intended for installation or replacement work performed by licensed plumbers or experienced plumbing technicians. The 1027 follows Douglas flush valve design standards, making it a direct-fit option for compatible toilet systems that use this valve configuration.
This flush valve is suited for residential plumbing applications where a Douglas-style flush valve is specified. It is typically installed during toilet repair, tank rebuild, or full flush mechanism replacement. Plumbers working on older or Douglas-compatible toilet tanks will find this valve applicable to standard tank configurations requiring this design type.
Designed as an OEM-style replacement flush valve for toilet tank assemblies that specify a Douglas flush valve configuration.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply to the toilet and fully drain the tank before removing the existing flush valve. Avoid over-tightening the locknut during installation to prevent cracking the tank. Verify water supply is restored and the flush cycle operates correctly before returning the fixture to service.
