Honeywell PRO45H-004-P10 Fill Valve

Product Description

The HONEYWELL PRO45H-004-P10 is a fill valve designed for toilet tank water supply control. It regulates the refill cycle after each flush, shutting off flow once the tank reaches the correct water level. This part fits into the standard fill valve installation position inside the toilet tank and is serviced by licensed plumbers and experienced plumbing technicians. The PRO45H-004-P10 belongs to the PRO45H series, which is engineered for reliable, consistent tank refill performance in residential and light commercial plumbing applications.

This fill valve is suited for residential toilet tank installations and light commercial restroom applications. It is installed inside the toilet tank and connects to the supply line at the tank base. The PRO45H-004-P10 is a direct replacement for failed or worn fill valves and is appropriate for service calls where the toilet runs continuously, refills slowly, or fails to shut off properly after the flush cycle completes.

Installation Notes

Installation should be performed by a licensed plumber or qualified plumbing technician in accordance with local plumbing codes and IPC guidelines. Shut off the water supply at the angle stop valve and flush the toilet to empty the tank before removing the old valve. Ensure the supply line connection is hand-tightened and then snugged with pliers — do not overtighten, as tank fittings can crack. After installation, turn the supply on slowly and verify the shutoff level and refill rate before returning the toilet to service.
