The WaterBoost WB-EXT Slimline 500 Mini3 is a high-storage variable-speed water boosting system for 3–5 bedroom homes. A 500-litre WRAS-approved slimline tank (700mm dia × 1500mm high) pairs with the DAB Esybox Mini3 external variable speed pump, delivering 50 l/min at 3 bar with WiFi, DConnect app, and Google Home and Alexa voice control.
The Esybox Mini3 sits alongside the tank rather than inside it — keeping the pump fully accessible for servicing and maintenance at any time. The tank connects directly to the mains via the pre-fitted ¾" ball float valve, and the system arrives fully pre-built with no site assembly required.
Supplied with union connections, ¾" ball float valve, 600mm hose, and By-law 30 kit. The tank carries a 5-year warranty and the DAB Esybox Mini3 a 3-year warranty. Please contact us for delivery timescales.
