The Leak Sealer from Sentinel is a super easy and convenient way of sealing minor leaks and weeping joints, especially those that are in hard to reach places like underfloor heating. Once in the system, it forms a soft seal over any leaking area within 24 hours, making it perfect for fast fixes. With the Rapid-Dose it makes fixing leaks in the system even quicker as you don’t need to drain or depressurise the system, and it includes an adaptor to fit directly into the radiator or boiler filling loop. The Rapid-Dose adaptor features Sentinel’s visible bullet, which will stop water from escaping the system and shows you when dosing is taking place as the bullet will move down the tube.
