Sentinel Internal Leak Sealer 1Ltr is rated 4.7 out of 5 by 45.
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

Rated 5 out of 5 by from It Works! I've had problems with pressure dropping on my combi boiler for a few years - not a big problem at first but recently was having to re-pressurise every few days. Used this leak sealer and pressure is holding - so far so good. Easy to use and a lot cheaper than getting the professionals in!

Rated 5 out of 5 by from Miracle product Had this problem on my boiler where I had to top up couple times a week for a year. In that time I had replaced the pressure relief valve and a leaky diverter valve but no change. I then came across this ‘miracle’ product after reading a few reviews. Bought the product on the Sunday - I found it easy to pour it into an empty magna-clean (had to fill it twice if pouring all 1 litre of the product). Topped up the pressure and left it around 1 bar. Instructions does state that it can take 24 hours for it work around the system. Well it’s now Wednesday and the needle on the gauge has not moved. I can now honestly say that product does work.
