A water flow control assembly comprises a pump 11 installable in a mains water supply line 10, a sensor 14 for measuring the rate of flow of water in the supply line and a control 13 for adjusting the speed of the pump when the pump is in operation in response to flow rate measured by the sensor. The control acts to limit the speed of the pump so that the flow rate does not exceed a predetermined value. A second sensor may detect water pressure going into the pump. A pump bypass may be provided further comprising a non-return valve. The flow sensor 14 may be positioned downstream of the pump. |
