At the start of my coffee journey I tested my rainwater tank water for hardness and recorded figures were 20 ppm for calcium and 25ppm total hardness.Have been using my newly purchased Alex Duetto from the onboard tank for a week but now want to plumb it in.
The home pressure pump (Davey Dynajet) provides 400kPa (at the pump) and pumps 30 metres to the house to a head of 4 metres.
The water is crystal clear, and drunk straight from the tap for 25 years.
What would you fellow snobs recommend to be placed inline to the water line for the Alex.
Particulate filter?
Pressure reduction valve? The machine wants 350 kPa at the machine and I doubt that after the water has traveled its tortured path from the water tank that it would be near the 400 that the pressure pump provides.
Opinions valued.
