Sentinel Internal Leak Sealer 1Ltr is rated 4.8 out of 5 by 36.
Rated 5 out of 5 by from Save on digging up the floors Had a tiny leak somewhere under the ground floor, so that the pressure kept dropping. No weep from the pressure valve, so I thought that I would try this stuff. 48 hours later it all looks good. Did a complete drain and flush before adding it using the simple filling kit into a radiator, together with the Sentinel inhibitor (which I had already bought). Can't give meaningful ratings for performance or reliability, as only 2 days into service.

Rated 5 out of 5 by from Well worth trying My 15 year old Worcester 24i combination boiler was losing pressure daily resulting in the overheat sensor tripping out. Told by heating engineer that must have a leak in system as nothing wrong with boiler. Assumed not in upstairs pipework or radiators as no sign of water damage. Did not fancy having to lift carpets and flooring down stairs to try and find leak. Bought Sentinel leak sealer to give it ago although a little sceptical it would work. BUT IT DID WORK. Boiler pressure now stable for last ten days. Only thing to be aware of is that it does not flow easily as is like thick PVA glue. So make sure if using tubing and funnel that it is large enough to flow easily. I drained system down enough to take off valve from upstairs radiator and fed tube into pipe. Worked for me. Better than lifting all the downstairs flooring! Happy days.

Rated 5 out of 5 by from Well worth the money I purchased this to sort out a small leak I had on my towel radiator, I removed the non bleed valve plug and used a length of tubing to remove a ltr of water, I then poured in Sentinel leak sealer, replaced the plug, turned on the system bled the radiator, hey presto no more leak. I would highly recommend this product to anyone who has the same problem.

Rated 5 out of 5 by from Sealed the leak Using this marked the end of a 2 month search for a leak that couldn't be found. The noise coming from the central heating pump has changed noticeably since adding this but I cannot comment on whether this is a good or bad thing... something to keep monitoring I think.

Rated 5 out of 5 by from Brilliant Had a mystery leak somewhere under floor that could not be detected, leading to regular pressure drops and topping up of system on a daily basis. I thought I'd give this product a try before ripping the entire flooring up and hey presto it worked! I poured it into the system through the top of the bathroom towel rail as this was easy access, turned on the boiler for a short while as per the instructions and that was it. Several months later still no problems and pressure is constant. One of the best products I've used, highly recommended.
