A WATER SUPPLY SYSTEM

A water supply system comprising: a first main inlet connection (101); a first main valve (111) configured to control water flow from the first main inlet connection (101); a second main inlet connection (102); a second main valve (112) configured to control water flow from the second main inlet connection (102) and a main outlet connection (104) to which water from the first main inlet connection (101) and from the second main inlet connection (102) is supplied via a main flow conduit (C3). The system further comprises a controller (115) connected with the first main valve (111) via a first signal line (L1), with the second main valve (112) via a second signal line (L2) and with a flow sensor (113, 114) via a main measuring line (L3); wherein the controller (115) is configured to set the main valves (111, 112): to a first configuration (210) in which the first main valve (111) is open and the second main valve (112) is closed; and to a second configuration (206) in which the second main valve (112) is open and the first main valve (111) is closed; depending on the flow value indicated by the flow sensor (113, 114).
