Having flushed my old CH system repeatedly with fresh water and
all-manner-of cleaners, I was disappointed to find that my MagnaClean filter
had "picked up" significant amounts of crud after 1 year of operation
(I had at some point either replaced or removed and manually flushed all
rads as well).
The material collected by the filter was approx half sludge and half gritty
As I had the main pipe route upstairs changed from 15 to 22mm, the
mechanical disruption as well as the improved flow could well have released
some more stubborn crud I expect.
So the question is, will the larg(ish) magnetite crystals form in the space
of a year, or is this more likely to be stuff that has been dislodged from
the old pipe work.
If this material is still being created, then I will have to look for a
possible cause. Haven't seen pump over issues and the layout around the
pump and vent appears correct.
