The questions asked are simple but the thread was posted in the wrong sub forum (new home). Pepsi_Drinker 99% of rainwater tanks seem to be using the Davey "Rainbank" system to automatically switch between the rainwater tank (if available) or the mains water when rainwater is not in the tank. RainBanks are fitted because the larger water tank companies that do the new house installations usually have a commercial association with Davey. I personally do not recommend the RainBank, my favoured automatic option is the clever Acquasaver that works off the mains water hydraulic pressure. http://www.acquasaver.com.au/ The Plumbing Code of Australia also allows bullet proof and much cheaper manual systems that require (simple) manual switching. It is rare for a new home owner to be told of their cheaper and bullet proof options. Pepsi_Drinker A new toilet uses around 6 litres / flush. 6 litres for a full flush, 3 litres for a half flush. Pepsi_Drinker Davey also sells various size accumulators, "Pressure tanks". I phoned up one of the largest rainwater tank / Davey pump suppliers in SA and outlined everything above and said .................. "Can I just put a large, or a couple of smaller, accumulators in the system so that the pump doesn't stop-start so often." Theoretically (discounting losses) if I put say a 60 litre accumulator in the system, and the toilet is 6 litres, the pump should only run every 10 flushes. The rainwater dude thought this was a great idea, but didn't know if it could be done, and suggested I contact Davey Customer Service. I was like......."Hey, every new house in SA (Australia ??) has this issue and I'm the first to ask this question....WTF ??" So, I rang Davey Customer service. They too had never heard of something this revolutionary The dude there went and asked his mate and came back with "No, Not possible". The Davey RainBank's Installation and Operating Instructions state: Do not use pressure systems or accumulators with RainBank®. 3in1 Supadiverta.
