• Stuart Turner STORMBOOST 300 3.2 Bar Mains Water Booster Pump - 47718

The STORMBOOST range from Stuart Turner offers a solid solution for domestic properties struggling with low mains water pressure. Ideal when you're looking to boost supply to a one or two bathroom home, the STORMBOOST 300 is a compact, high-performance mains booster pump that connects directly to the incoming cold main.

Compact design, high output

Engineered to fit neatly under a standard 600mm wide kitchen larder unit, the STORMBOOST 300 delivers up to 27 L/min at 3.2 bar for 11 minutes, then continues at 12 L/min until demand stops and the integral pressure vessel recharges*. This makes it ideal for properties with intermittent low pressure or peak usage demands.
