hi ive a combi system with 7 rads off it and wanting to add another rad.
is the process as follows......
turn off boiler and stopcock, drain system of lowest rad with drain off, tee into nearest flow/return to new rad position, fit new pipework to new rad, add inhibitor to upstairs rad, refill system and keep checking pressure of 1.5 bar, keep bleeding all rads til full and make sure pressure is 1.5 bar.
hope this makes sense.....
