<p>A device and its method of use are described which allows any tank collected rainwater to be utilised automatically with a reticulated water supply. The device (1 ) comprises a hollow substantially T-shaped body (2) having a first inlet (3) and a first outlet (4). The integral hollow leg (6) of the T-body (2) terminates with a second inlet (7). A hose or pipe (10) leading from a source TW of tank water is connected to the inlet (7). One end of an internal bore (11) of a hollow cylindrical body (12) has a jet (13) attached. The body (12) is connected to the inlet (3). The other end of the body (12) Is plumbed In to a source of reticulated water RW. The position of the jet (13) within the body (2) can be varied. The reticulated water RW Is restricted to pass through first the body (12) and then the jet (13). A hollow cylindrical body (19) incorporates a venturi (20). The body (19) is connected to the outlet (4). The other end of the body (19) is plumbed back in to the piping associated with the source of reticulated water. The position of the body (19) can be varied. The reticulated water RW, and any tank water TW within the body (2), is restricted to pass through the venturi (20). Upon activation, the flow of reticulated water RW into the body (2) is restricted by passing through the jet (13). As the pressure within the body (2) is consequently lowered at the exit of the jet (13), any rainwater TW is drawn from the rainwater tank through the hose or pipe (10) into the body (2) to be combined with the reticulated water RW in the body (2) before passing through the venturi (20).</p> |
