This 500ml leak sealer liquid is designed for use in sealed central heating systems experiencing pressure drops due to small, inaccessible leaks or weeping joints. Suitable for application by heating engineers and plumbers, it is introduced directly into the system via a dosing point.
Commonly chosen on refurbishment or maintenance jobs, the sealer assists in maintaining system pressure without the need for immediate mechanical intervention. Its formulation allows it to circulate with the system water, targeting slow leaks to help limit downtime or further water loss in residential and light commercial installations.
