The DAB Esybox with Esytank 500 is a complete, ready-to-install water pressure boosting system that solves three problems at once: low mains pressure, restricted mains flow, and properties where direct mains connection isn’t permitted. A variable-speed Esybox pump draws from a 480-litre HDPE break tank, delivering constant boosted pressure on demand — quietly, efficiently, and with full WiFi monitoring through the DAB H2D app.
Complete system — Esybox pump, Esytank 500 (480 L), Esydock, suction pipe, foot valve, delivery pipe, and float valve all included
Up to 120 l/min and 6 bar — variable-speed pump with up to 50% energy saving vs fixed-speed
43 dB(A) operation — water-cooled motor in sound-absorbing housing, suitable for utility rooms and cellars
WiFi and voice control — DAB H2D app, Google Home, and Amazon Alexa compatible
Pump WRAS approved — tank manufactured from food-grade HDPE
Expandable and modular — auxiliary tanks connectable on 3 sides; up to 4 pumps can be linked
3-year DAB manufacturer warranty when purchased from Anglian Pumping Services

More about this product
The DAB Esybox with Esytank 500 is a complete, ready-to-install water pressure boosting system combining DAB’s flagship variable speed booster pump with a drinking water storage tank holding 480 litres usable capacity. Designed for domestic and light commercial properties where mains pressure is insufficient or where direct mains connection is not permitted.
The Esybox pump intelligently adjusts its speed to match demand, delivering constant pressure to every outlet while using up to 50% less energy than fixed-speed alternatives. The Esytank stores water from the mains during low-demand periods, ensuring a reliable supply even when mains flow is restricted.
Both components are supplied with everything needed for installation, including Esydock, suction pipe with foot valve, and delivery pipe. The Esybox pump is WRAS approved for potable water. Backed by a 3-year DAB manufacturer warranty.
Pump WRAS approved — potable water
The chart shows the relationship between flow rate and head for the Esybox pump. As demand increases, the variable-speed inverter increases output — but as with any pump, available pressure decreases as flow rises. Maximum head is 60 metres (6 bar); maximum flow is 120 l/min.

All three systems use the same DAB Esybox pump. The differences are storage capacity, tank format, warranty, and price. Use this table to identify which fits your application.
