When low water pressure is affecting showers, taps and appliances, the Multiboost 350L Simplicity Rectangular Coffin Tank delivers a robust, packaged solution for improving pressure and flow in domestic and light commercial properties. Designed to work as part of a pressure booster system, this all-in-one unit combines a 350-litre non-corrosive storage tank, pump and controller — giving you consistent water delivery even in low mains pressure areas.

The rectangular coffin-style tank is engineered to maximise usable water storage while fitting neatly into utility rooms, garages, plant rooms or under stair voids where headroom may be limited. Its WRAS-approved construction ensures reliable performance with potable water, and the included controller manages automatic pump activation based on demand. Intelligent dry-run protection safeguards the pump against damage while easy-access unions simplify installation and servicing.

Whether addressing low supply pressure or supporting multiple outlet demands, the Multiboost Simplicity Rectangular system delivers a practical pressure-boosting solution that’s built to last.
