When you say 'make sure the mains filling loop is switched off' does this mean the tap has to be in it's normal closed position or do I need to switch it off somewhere else to stop water coming through when it is opened and attached to the can?
You are technically supposed to remove them in at least Scotland too, no permanent connection (Water Fitting Byelaws 2000 Scotland) but many people don't remove it for whatever reason when the boiler is topped up.
What Fernox DOES NOT TELL YOU anywhere i.e. info on their website or can "the leak sealer will not work as it does need access to air, so any pipework that is leaking that is either buried in concrete or lagged will not seal up" . YES I RECEIVED THIS FROM FERNOX BY EMAIL AFTER BUYING IT AND WASTING MY TIME PUTTING IT IN THE SYSTEM.
