Hi, I have always used Sentinel X500 and never had an problems. The worst part is the cost but i haven't found any much cheaper on the market

as i am draining the system so i can fit a new rad is it best to add the inhibitor to the tank in the loft when i am re-filling the system. as a few friends have sed it is best to add to a rad put i do not have a top bleed valve on any of my rad's.
