hello, i have a worcester bosch 28i condensing combi boiler, i want to flush the system, as i have put some cleaner in a week ago, now i have to flush the system before i put the inhibitor in.
what i want to know is...do i turn on the water valve which fills the combi system up, as well as open the drainage valve downstairs...so in theory flush thru the system.....or do i have it all wrong....help!! lol.
