[QUOTE="Danny Boy, post: 1143645, member: 14104"] I have a 0.75kw Hurricane pump (JSW10M) and controller (PC13) with 5000l tank. Our problem is that one section of our town does not have a reservoir, so if the power goes so does the water... What I would have done differently is to use a smaller pump (perhaps even the 0.37kw) as it is quite heavy on my backup power and it is way over spec'ed for my needs (able to do 80l/m for a single story). Take a look at your requirements, look at the [B]flow rate[/B] (usually indicated in litres per hour, but divide by 60 to get litres per minute which is easier to use - run 2 or 3 taps concurrently and measure the l/m of each to get an idea of what you might need) and [B]head[/B] (high of which the water must be pumped - if it is a single story and tank is on the ground, it is usually 3-4m).
