About six weeks ago i added Fernox corrosion inhibitor to the system.
The system was drained, for a new hot water tank, refilled with
ordinary water, left in for one week, drained again, refilled and
Now in the header tank there is white lumps like small peices of
polystyrene and like a film of jelly ontop of the water. This is just
on the top and it dispursed when mixed up.
Is this normal? Or what have we done wrong?
