Rated 5 out of 5 by from Well worth it I used 2 bottles of this in a newly refurbished rental property, the system was loosing enough pressure each week to shut the system down with no leaks evident. It took a day or 2 to circulate properly and start working. That was 6 months ago now & I haven't had to even top the system up 1 time. Worked perfectly for me

Rated 5 out of 5 by from Successful last ditch attempt Before calling in insurance claim for a leak detection company (some pipe work under tiled floor which couldn't be accessed) finally tried this product. There had been a steady slow reduction in pressure of .3 bar every week. Large house but was able to isolate which area leak was happening. Added 2 litres and ran hot for two days then opened up remainder of house heating. Leak stopped! This was 4 months ago and so relieved that I thought the product worth promoting.

Rated 4 out of 5 by from Seems to work ok Used this in both combi and traditional heating systems. Took a while to seal a leak in the trad system but did it in the end. Combi system was gradually losing pressure (quite slowly) so it will be a while before full confidence is achieved.

Rated 5 out of 5 by from Great! I bought this today and added it to my Combi boiler system, it was a last-ditch effort before having to rip up my wooden floors and smash the screed below it to gain access to the pipework My 8-year boiler was losing pressure and I needed to top it up approx every 2 hours, the pipework is about thirty years old and the radiators vary in age I really had no faith in the product, rest assured it lived up to the hype, it sealed the leak straight away, I don't know how long it will last but I am over the moon at the minute, I have now ordered the Sentinel X200 and X800 products to cleanse and maintain the heating system.

Rated 5 out of 5 by from Sentinel leak sealer Had a bad leak from a radiator pipe into the valve. Added the leak sealer through a towel rail after syphoning out a litre of water. Leak stopped within a couple of hours saved a much bigger drain down and repair would highly recommend.

Rated 5 out of 5 by from Wow - stop leak within 30 mins Bought new radiator but it had a minor drip coming from the body with no access to it, should of really taken back this rad (from a another retailer) but the chew to drain down, remove from wall, and solid fixed brackets, etc, etc I thought it was worth a go. Wow very impressed work straightway. I’m keeping an eye on it... but it’s done the job so far after 3 days
