Telford Tornado Elete Un-vented, To change some tap washers I turned of the mains on turning on again I,ve lost pressure in the tank (the expansion tank above has pressure) normally 1 bar. The system seems to be working normally though. Any ideas?

Couple of questions

The 1 bar you speak f is this in the red vessel or the one directly on top of the cylinder?

How do you know you have lost pressure? Noticeable at the taps?

The red cylinder on top reads 1 bar the dial on the lower main cylinder reads zero. Pressure upstairs is good downstairs not so good.
