    BASE2DRAIN basement pumps


    Introducing BASE2DRAIN; the safest, most reliable and efficient range of basement pumps from Marsh Industries.

    Suitable for virtually all subterranean sites, Marsh BASE2DRAIN systems are designed in accordance with British Standard European Norms: BSEN12050, BSEN752, BSEN752-6 and also carry third party approval for material fire safety and structural integrity.


    A Marsh BASE2DRAIN basement pump is necessary when discharge from a subterranean site, such as an underground car park or a home basement, is required but gravity discharge is impractical.

    Available in a wide range of sizes and capacities, all BASE2DRAIN systems are supplied as a complete unit with either twin or triple submersible pumps and high quality internal pipework/fittings as standard.

    Marsh Civils’ technical team can work closely with you to identify all key requirements in specifying the right system for your project.

    • Variable invert depths and orientations to suit individual site conditions
    • Smooth internal walls improve pump efficiency and eliminates ‘dead spots’ which can lead to odours and septicity
    • Unique ‘keying-in’ lip assists anchoring into concrete surround
    • Structurally robust, fire tested GRP shell
    • Acoustic sealant around lid provides an effective sound barrier and prevents air and moisture from entering the tank
    • Pre-assembled pipework for fully automatic operation
    • Market-leading submersible pumps ensure maximum reliability and efficiency with minimal clogging or wear
