I need to put some Inhibiter into my central heating system. If I bung the Sentinel X100 in the expansion tank and leave the water make-up on, how much water would I need to drain down to get it all (or most of it) into the circulating part of the system ?
The expansion tank is in the attic ( two storey house ) and I don't want to shut off the water make up (unless absolutely necessary) as I'm afraid I might drain down to the point where air is introduced to the system and I end up having to bleed all ahe radiators.
The system is currently full of clean water - My plumber drained down when extening to two new radiators but didn't put any inhibiter when he refilled the system....
