Rads giving coffee brown water.
Had our system flushed 2 years ago, first with a strong cleaner, believe he used x800. Flushed twice.
Then had 2 bottles of x100 and 1 bottle of x200 added. Think there are about 21 rads.
Not thought to check in a while, as its getting cold, checked for air upstairs. Nothing, but greeted with orange looking water when bleeding. Bled into a cup it looks dark brown / coffee like.
Before the drain and x100/x200, the water was like a straw yellow colour.
Any ideas?
Noticed some of the TRV's weeping occasionally.
thanks
