So it’s not all perfect after all. The rainwater harvesting system is not working despite much tinkering and hours on the phone to technical help. After trying various settings and cleaning out the tank and pipe work the inescapable conclusion is that the pump is broken. Thankfully it’s under warranty and the new one has just arrived. I’ll let you know if it works once it’s in. Just to be clear, we do still have the ability to flush the toilets since the default setting is that the system is fed direct from the mains (a good thing too with potty training going on). So we are flushing our toilets with drinking water for now, just like everyone else.
