While waiting the the tank to cycle, I have been working on a side cabinet that will contain the ATO tank, a bit of storage and the electrical stuff.
We have purchased an ELOS dIGITAL SYSTEM and managed to test it today - and we had one problem. After the pump shut off, the water started to siphone from the ATO tank into the sump

. How do we prevent that?
Here are two pictures of the first part of the cabinet. The tank is on a shelf on slides (thanks Jason for the idea!).
