I looked at my freshwater hydrophore system this morning and wasn`t very impressed of the design. No suction to the other fw tanks, no pressuretank, no pressureswitch,in short,poor engineering. I`m posting my new idea. Blue suctionline to the common suctionline to all the fw tanks, red deliveryline via relief/pressureswitch ( I`m not 100% sure about that) connecting via the handpump supplyline to the headertank (daily consumptiontank) hopefully this would work better.
But in general I believe Simon shouldn`t bader about this system just delete it.
