SUPADIVERTA can prioritise diversion to one tank and then divert to a second tank during heavier rain or once the first tank is nearly full.
The diagram shows two same height tanks with deleted overflows.
Tank A has priority feed.
Install SUPADIVERTAS on DOWNPIPES A and B with the intersect height of the SUPADIVERTAS reservoir walls and filters a couple of cm below the bottom of the tank’s overflow.
The house brick mortar lines or weatherboards can be used for line of sight.
Connect the vertical drops from both SECOND priority outlets to a larger shared horizontal pipe connected to a bottom inlet on tank A.
Connect the vertical drops from both THIRD priority outlets to a larger shared horizontal pipe connected to a bottom inlet on tank B.
When Tank A is at a low level, water from both SUPADIVERTAS flows freely to that tank. As TANK A becomes full and the head decreases or the rain becomes heavier, the water level in both SUPADIVERTAS will rise above the third priority outlets and start filling tank B.
