Hi, occasionally get a low pressure fault on ce natural heating system (f&e) in loft. No signs of any leaks plus no recent bleeding of radiators. Any suggestions bar topping up f&e tank noting I thought ballcock valve would refill automatically as free moving?
Boiler serviced annually with no issues raised,
Thanks in advance,

Hi soccy
Suggest you look up the minimum operating pressure for you boiler. If it’s being fed by a tank in the loft you will be getting less than 1bar.
