I put central x400 in system 4 weeks today. I flushed out today but have realised I may not of flushed 3 of the down stairs rads as I should of used the drain offs on the downstairs radiator separately.
I would of got most out but may of left a little in.
I can't get it flushed again but anither 2 weeks.
Can this cause any damage ?
