Currently use 2 IBCs set up as follows:
DI
T-piece
Hose to each ibc.
Number 1 ibc has a float valve which when it stops, the water at the t-piece diverts to the second ibc, as the outlet is higher.
The lads drop the transfer pump in the one with the most and take from that.
Now, I'm about to fit a Liquid Logic S2 static system controller, and would like advice on the best and least complicated way for the IBCs to be joined, so when one is full, flows into next one.
Would a simple hose at the top, creating an overflow work simply?
