The WaterBoost Grand 3000 is the middle of the Grand range — a 3,000L Enduramaxx slimline tank paired with a DAB Esybox Twin for full duty/standby pump redundancy and 140 L/min boosted output. Adds 50% more stored volume than the Grand 2000 while staying under 1 metre wide — the sweet spot for larger domestic properties or light commercial premises with space along a wall or side passage.
A single-tank design — no linking pipework, fewer joints, faster install than a twin-linked setup. The Esybox Twin pump frame runs two DAB e.sybox units in wireless duty/standby, alternating priority every 23 hours, with full pump redundancy if one unit fails.
