flushing rads

[dabaldie]

i've (over a period of months) replaced all the rads in the house and would like to flush them all through now. (i didnt want to do it before as i knew i'd be draining the system many times).
btw the water is generally clear when i drain down the system except for a few black/brown gurgles occasionally.
do you think the system relly needs a flush and will it help anything?... efficiency etc.?
and should i then use a corrosion inhibitor after or is that a waste of money?

Probably not.

Definitely use.
