WaterBoost WB – Advant slim 500 mini3 2103210SL

The WaterBoost WB-Advant Slim 500 Mini3 is a compact slimline water boosting system for high-demand domestic properties with tight plant room access. A 500-litre WRAS-approved UK-manufactured Advant slimline tank (500mm W × 1100mm L × 1250mm H) pairs with the DAB Esybox Mini3 external variable speed pump, delivering 50 l/min at 3 bar and up to 5.5 bar maximum — with WiFi, DConnect app, Google Home and Alexa voice control. At just 500mm wide, the vertical slimline tank passes through even the tightest doorways with 262mm to spare — opening up cellars, loft installs and utility spaces that no standard-footprint 500L tank can reach. The Esybox Mini3 sits alongside the tank for full pump accessibility, running at a quiet 45 dB(A). The tank connects directly to the mains via the pre-fitted ¾” ball float valve, with 1.5” outlet. All interconnecting pipework is supplied — no site assembly required. The UK-manufactured tank carries an outstanding 10-year warranty and the DAB Esybox Mini3 a 3-year warranty. Delivery is typically 1–2 working days. 50l/min @ 3 bar 500L Tank storage 500mm Slim width 10yr Tank warranty 262mm doorway clearance WiFi · Google · Alexa WRAS tank & pump 5.5 bar max By-law 30 kit included Type AB Airgap available UK-manufactured 1–2 day delivery
