WaterBoost CAT 5 WB-Coffin 500 Mini3 Variable Speed 2207C2120CT5

The WaterBoost WB-Coffin 500 Mini3 Cat 5 is a complete, variable-speed water boosting system that delivers the highest level of backflow protection in common use in a low-profile coffin format — fitting under stairs, inside cupboards, and in low-ceiling garages and plant rooms where an upright tank would not. The mains supply discharges into the tank through a Type AB air gap — the float valve sits above an unobstructed air gap and the cistern carries a weir overflow sized to handle the full inlet flow. Because there is a permanent physical break between the incoming mains and the stored water, the system protects against fluids up to and including Fluid Category 5 — the most hazardous category. The DAB Esybox Mini3 variable-speed pump draws from the 500-litre tank, delivering a consistent 50 l/min at 3 bar. The intelligent inverter adjusts continuously to match demand, maintaining stable pressure across multiple outlets with low noise and reduced energy use. Supplied complete with weir overflow, ½” connection, 1″ brass outlet and all interconnecting pipework. WiFi via the DConnect app, Google Home and Alexa compatible. 3-year DAB warranty. Delivery typically 2 to 3 working days.
