* Distances are approximations, enter postcode for precise quote. Price is per tank. † Kingspan considers pickups the same as Metro as handling and loading is still required for each tank. Tanks are fill tested for leaks prior to leaving factory and all duty of care is with you as the end customer for pickups. Any damage occurred during transit will void tank warranty. Tank delivery is strongly encouraged when possible, as Kingspan sends out a team who will absorb all the risk when carrying your tank to its pad (access permitting). ‡ Tank Shop only guarantees supply and delivery of tanks as specified to the delivery address. Any onsite installation and craning of any kind must be organised by the customer. While attempts are made to position tanks to the prepared pad, Tank Shop does not guarantee siting. Such is at the discretion of the delivery team on the day to decide whether it is safe and possible.

    Base colours are tightly bonded to the steel sheets as part of the steel fabrication process. We recommend choosing a base (genuine Colorbond steel) colour as they are more durable than painted colours. Painted colours offer a greater selection of colours, but also carry an additional cost to paint them on.

    Add High-Flow

This system provides a 100mm inlet at the side of your tank (which is good if you can't run downpipes into the top of your tank due to height restrictions), and can handle flow rates up to 600l/min while filtering your rainwater. An inlet strainer that can handle high flow-rates will be included in any case. Only add if you know what it is, otherwise you don't need it.

    • High-Flow Filter:
    Kingspan High-Flow Filter will be installed inside your tank at your desired position (exteral parts provided loosely). It includes a 100mm Inflow and 100mm Overflow on the same side of tank, making it ideal for wet systems (where pipework comes up out of the ground next to your tank).

Please allow 800mm space on the side High-Flow will be installed.

  • Tank Fitout (if known)

    Note: Included in each tank build is 1x 25mm outlet (base of tank), 1x 25mm ball valve, 1x 400mm inlet strainer + UV light guard (on top of tank), 1x 100mm moulded overflow.

    Ball Valve Position

    25mm Ball Valve Outlet is located at the very bottom wall of your tank and is where you will access water from your tank and/or connect to external pump. Note: A 25mm outlet is required on all tanks for manufacturing and testing purposes.

    IMPORTANT: The included 25mm Outlet with Ball Valve is highly recommended on every tank as this is the only size outlet that can sit at the lowest point (first corrugation high on tank wall) allowing water to be fully drained should such ever be required. 

    Inlet Strainer Position

    400mm Inlet Strainer is located on top of your tank and is often best positioned closest to the downpipes from the gutter. It is a mandatory requirement as it doubles as a maintenance hole for inspecting and accessing inside your tank.

    Overflow Position

    100mm Overflow is located at high up on the wall of your tank and best positioned closest to the stormwater drainage point. Note: 100mm is the standard overflow size. If you need 90mm, then we recommend a 100mm to 90mm reducer when procuring your pipework.

    IMPORTANT: Overflow is highly recommended on every tank to avoid water overflowing at inlet strainer. Only select "Not Required" if absolutely sure.

    Highflow Position

    Kingspan's Highflow has a 100mm inflow (higher) and 100mm overflow (lower) located on the wall of your tank, which is normally best positioned closest to your rainwater charge line and stormwater drainage. NOTE: Please ensure your inlet isn't positions at the same side as your high-flow (as it will clash when installing).

    Fire Outlet Position

    Fire outlet is located at the bottom wall on the side of your tank that is easily accessible by firefighters.
