Hi all, I've already added some value to our PPOR by installing a water tank when we built. We have 1 x 6000L tank under our deck. There are two downpipes from the roof that drain into the tank. The tank is hooked up a Rainbank pump and connected to our outside tap and two toilets. We could fit up to 3 *more* water tanks under the deck, but I'm struggling to understand how they would hook up to the existing tank. Has anybody achieved this aim? Any ideas? Cheers! -- MJ.
