The pump conduit (4) extends via the pump to the hydrophore, and an outlet pipe (10) runs from the cleaning appts. (8) to the well (5) to feed cleaned water to it. The hydrophore or pressure vessel (6) distributes water to different usage points (2), and also feeds it continuously to the cleaning appts. (8). The cleaning appts. is connected to the pumpt conduit on the suction side of the pump (3) by an inlet pipe (9). A valve (14,15) is fitted in the inlet pipe to prevent water or air being pumped from the cleaning appts. when the pump is moving water from the well to the hydrophore. |
