WaterBoost WB – Advant slim 500 Esybox 2103110SL

The WaterBoost WB-Advant Slim 500 Esybox 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 external variable speed pump, delivering 80 l/min at 3 bar and up to 6.5 bar maximum — with WiFi, DConnect app, H2D technology, 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 sits alongside the tank for full pump accessibility, running at an exceptionally quiet 43 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 a 3-year warranty. Delivery is typically 1–2 working days. 80l/min @ 3 bar 500L Tank storage 500mm Slim width 10yr Tank warranty 262mm doorway clearance WiFi · H2D · Google · Alexa WRAS tank & pump 6.5 bar max 43 dB(A) — ultra quiet By-law 30 kit included Type AB Airgap available 1–2 day delivery
