central heating,
water(warm\hot) returning to the small header tank, advised that the system needs cleaning. Used sentinal by dropping 2 heads of water to get it into system then topped up and running(3 days).
water still overflowing(trickling)when either system running. BUT the system does not overflow! Just rises a bit, and is definately a different colur.
Where\What is happening to the water being pumped into the header tank? Shouldnt it overflow?
