    Post How to extract water from a water tank

    I have a 60 year old cottage and I'm wanting to replace the well rusted corrugated galvanised iron tank and I already have a 10,000L poly tank from my mine claim but the water inlet is 150mm too high to fit under the gutter outlet on the house.

    The water inlet being too high I'm thinking an easy solution would be to set the tank 200mm into the ground but since the water outlet is at the base how would I go about extracting the water.

    Wondering if one of those 2 tap self priming Davey pumps would be suitable, lets say there's only 30cms of water in the tank and where the water line feeds into the laundry is 40cm would the pump suck the water up okay or does anyone else have an easy solution.

    Maybe I could fit an outlet at the ground level like the ones that's fitted to poly cattle troughs but that would leave 20cms of water that can't be used.

    I really don't want to go buying corrugated tank made to suit the gutter height as the freight is too expensive to make it worthwhile.

    You can use any pump and fit a non-return valve between the pump and the tank.

    Nearly any pump will pull that head. It won't be a problem. If you want to prevent backflow as said a 1 way valve but a piston pump for example will do that automatically. 1 way valves are cheap and readily available.

    Good luck
