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!
