The boiler that we have is a Valiant Thermocompact - the warranty for it expired long ago...Thanks for the reply!

A plumber fitted a Magna Clean for us recently and we now want to put leak sealant through the system (rather than fork out hundreds to pull all of our floors up to find a leak we have). Can anyone explain the process to us? I.e. do we need to drain water out before putting the leak sealant in...
