Water storage vessel for mains water supply
A water storage vessel for use in a mains water supply has an inlet 8 for connection to an upstream pressurised mains water supply, an outlet 9 for connection to a downstream pressurised mains water supply and a valve (29 figure 3) selectively operable to ambient atmospheric pressure. The valve is switchable between a closed position at which the vessel stores water above ambient pressure, and an open position at which the storage vessel stores water at ambient pressure. The storage vessel has a pump (22 figure 3), a secondary outlet (21 figure 3) connected to the pump and to the same downstream pressurised mains water supply. The mains water supply system is operable in a first mode in which the upstream mains water supply is above ambient pressure not less than a predetermined value with the valve closed, and a second mode in which the upstream mains water supply is below the predetermined value, and the valve is open such that the storage vessel is at ambient pressure not less than the predetermined value. A later embodiment relates to a method of operating the water mains supply system.
