Mansfield 630-0042 Ballcock Repair Kit

Product Description

The MANSFIELD 630-0042 is a ballcock repair kit designed to restore proper fill-valve function in residential toilets. Ballcock assemblies control the refill of the tank after each flush cycle. When the original ballcock begins to leak, run continuously, or fail to shut off, replacing the internal components with a manufacturer-supplied repair kit is the standard service approach. This kit includes the replacement parts needed to rebuild the existing ballcock rather than replacing the entire fill valve, making it a practical repair option for licensed plumbers and experienced service technicians.

This repair kit is suited for residential toilet tank service where the existing MANSFIELD ballcock assembly is installed. It is commonly used during routine maintenance calls, rental property turnovers, and warranty service on MANSFIELD toilet fixtures. Installation is typically performed by a licensed plumber, though experienced DIYers familiar with toilet tank components may also complete this repair.

Key Features

• Manufacturer-supplied components designed for OEM-compatible rebuild of the ballcock assembly
• Restores proper tank fill and shutoff function
• Reduces service cost compared to full fill-valve replacement
• Intended for residential toilet tank applications

Compatibility

Installation Notes

Shut off the water supply at the angle stop valve below the toilet tank before beginning any repair. Flush the toilet and remove remaining water from the tank before disassembling the ballcock. A licensed plumber should perform this repair in jurisdictions where plumbing work requires a permit. Follow all applicable IPC and local plumbing code requirements for toilet tank component service.
