So we just had the garden landscaped and we're about to plant vegetables and put down grass seed, so we're going to need A LOT of water and we want to get a water butt so we don't have to run a hose from the kitchen through the house (if the predictions are right, there will probably be another hose pipe ban this summer, so that might not even be an option). Anyway, we have cast iron drain pipes, so there's no way we can attach a diverter for the water butt. Is there another option? Something that attaches to the bottom of the drain pipe and magically swooshes the water into the water butt? Giant funnels to catch the water as it falls from the sky? Fairies to water the garden at night?
