Site visit with the ATU installer earlier in the week, which lead to some more tree-pruning so the excavator had enough vertical clearance to get the tank in where I wanted it. The other fun bit of information was “I need to put 6,000L of water into it as soon as it’s installed” – if it rains heavily after installation, runoff fills the hole around the tank and the tank floats out of the ground. This is bad.
The only problem with this is my only water supply is….oh, 75m away at the other end of the block.
One trip to Bunnings, and 75m of irrigation pipe, later and I have water down the back end of the block.
