EcoRenovator - View Single Post - Harvested rainwater for non potable use in the home

I now have a mixed source supply for our toilet cisterns. The schematic is much like a manual version of the schematic posted by Tango Charlie. Instead of solenoids, I simply use ball valves. Our plumbing code requires double check valves to ensure no backflow as well as a check valve to make sure the mains water doesn't go back up through the pump and into the tank. The outlets are connected to the toilet cistern and the clothes washing machine. I have noticed very few drawbacks to using rainwater as a source. We are getting through about 100L/day of rainwater, most of which is inside the house.
