    Overflow runs after about an hour of i8nactivity. House has no wet system heating just 2 x immersion in single cylinder tank with overfflow and return tank in loft serving 1x sink 1 x whb and 1 bath & wc. Renewed all taps all mixers tank gradually fills takes about an hourcand then overflows until hot is used then repeat. Put new ballvalve in header tank does it whether cylinder hot or cold immersions on or off. Seems to be back surging up cold outlet from header tank and gradually filling tank to overflow same now as before renewed everything - any clues?? Can i put a non return valve on the flow from header or will that cause other problems??
