Using the shower tonight the pressure suddenly dropped. The whole house now gets a not-very-pressurised water flow. It has always been fantasticly powerful.
So I looked in the airing cupboard, the pressure guage at the top of the tank is only Reading half way towards the green zone. So I turned the valve tap I usually go to (well, last time it did this about 6 months ago) that usually makes the pressure guage go back up again, but it did nothing. I'm sure normall there's an audible hiss as the pressure gets let back in?
Any ideas?
