Leak Sealer
Bought this to seal a small leak at valve. Used funnel and pipe to fill into drained radiator that was leaking. Filled and started boiler. No more leaks!

Works well
I bought this product after being unable to find a leak in my central heating system. 3 weeks this product has been in and so far I have only had to fill up the system after a few days and since haven’t had to top up the system (which before I was doing a couple of times a week) It was quite thick and not all that easy to get into the system (a towel rail is the easiest point, but I don’t have one) so this was a 2 person job to get it in. So if it hasn’t fixed the issue, it’s certainly slowed it down.

Long lasting fix for leaks
I refurbished an old cast iron radiator. Did a leak check before hand and was happy not to see any watering leaking from it. So installed it in my kitchen. However, next day there was water on the kitchen floor from two small leaks between the sections of the rad. Had a look online how to tackle the problem and was lead to Sentinel Leak sealer. I poured it into my expansion tank and it stop the leak within minutes. That was 6 months ago and still no leak so I really recommend this product

Working well
My old Worcester 24cdi was dripping from the expansion vessel , losing pressure every day . I added sentinel leek stopper to a radiator and over the next few days the leak was almost non existent . I'd imagine that over the next few days it will stop altogether . Highly recommended

Stopped pulling in air.
After fitting a new bathroom the boiler started to bang and I was having to bleed air from the system every few days! I looked everywhere for a leak that might be pulling air where I had made alterations but couldn't find any obvious leaks. Rather than lift every floor to find a leak that didn't seem to be dripping water I tried this product. Its been over a week now with no boiler banging and when the bleeds are opened there isn't any air! I recommend this product for any one that has a leak that doesn't appear to exist!
