How to stop the overflow from an F and E tank when the ball valve is ok

The problem. You have an overflow running from the loft you take a look at the cold water storage tank and find it is ok, you then look in the F and E tank (the small one that fills and vents the heating and hot water system) and see that it is overflowing. You renew the valve in the tank only to find after a few days it is overflowing again. The answer is easier than you think . Save money and do it yourself. I will show you how.
