WaterBoost WB-INT Slimline 600 (300 + 300) Variable Speed 2402310D

The WaterBoost WB-INT Slimline 600 is a twin-tank variable-speed water boosting system for 3–5 bedroom homes with heavier demand. Two 300-litre WRAS-approved slimline tanks (600L combined) are joined by a dedicated link kit, drawn by a single DAB Esybox Diver internal variable speed pump — delivering up to 100 litres per minute at up to 5 bar. Mains water fills the AUX tank via the pre-fitted ¾” ball float valve and flows through the link kit into the main tank, where the Esybox Diver pump sits submerged and draws off. Water continuously turns over rather than sitting static — no dead-leg, no stagnant corner. WiFi connectivity via the DConnect app enables remote monitoring and voice control via Google Home and Amazon Alexa. Each tank is 600mm diameter × 1200mm high, so both still fit through a standard doorway individually — combined footprint 1250mm × 600mm installed as a pair. Arrives fully pre-assembled — no site assembly required. Tanks carry a 5-year warranty, the pump a 3-year DAB warranty.
