The WaterBoost WB-EXT Slimline 300 Mini3 is a variable-speed water boosting system combining a 300-litre WRAS-approved slimline tank (600mm dia × 1200mm high) with the DAB Esybox Mini3 external variable speed pump. It delivers a reliable 50 l/min at 3 bar with WiFi, DConnect app, and Google Home and Alexa voice control — making it the best-value variable-speed option in the slimline range for 3–4 bedroom homes.
The Esybox Mini3 sits alongside the tank rather than inside it, providing easy access for servicing and maintenance. At 600mm diameter the tank fits through a standard doorway and can be installed under stairs, in a garage, or in a utility room. The mains connects directly via the pre-fitted ¾" ball float valve. Supplied fully pre-built with no site assembly required.
Includes 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.
