Rated 5 out of 5 by from Works a treat I was topping up my combi boiler twice a day by the time the leak was realty bad. As the leak was under a sealed floor it was Impossible to access. After draining enough of the system to put in 1ltr of the leak seal in an upstairs towel rail, topped the system back up. Ran the system over the weekend on usual times. By Monday the pressure in boiler has been maintained. Happy days! I would defiantly recommend.

Rated 1 out of 5 by from Failed to seal the hidden leak I used the product as directed. However, I cannot recommend this product as its application has had no impact on the rate at which water continues to drain from the central heating system.

Rated 5 out of 5 by from Top Leak Sealer Combi boiler system was losing pressure but couldn’t find where. After adding and running this through, all sorted and now no pressure drop at all.

Rated 4 out of 5 by from Leak sealer Had a problem with a combi boiler heat exchanger pressures kept going down. This stuff seems have fixed it. Most people said it was a new boiler but on day 2 I don't think so

Rated 5 out of 5 by from This is brilliant! The pressure in my boiler has been dropping every day for the past 6 months and my plumber recommended I try sentinel. I was certainly sceptical but seems to have fixed the leak and the the boiler has been fully pressurised for the past 2 weeks! One happy customer!
