System has needed topping up twice a year since installed (4 years ago) . Low pressure light comes up and normally just top up from below.
Now it appears that the water isn't getting into the system. I know that it is coming through and the valve is open, however the low pressure light remains as does the cold water and no heating.
Any thoughts / ideas or suggestions????
