More about this product
The WaterBoost WB-Advant 1000 Esybox is a complete, high-capacity water boosting system combining a 1000-litre WRAS-approved storage tank with the market-leading DAB Esybox variable speed pump. It is designed for larger domestic properties and light commercial applications where a smaller tank system would not provide sufficient storage.
Capable of delivering 80 l/min at 3 bar, the Esybox pump continuously adjusts its speed to match demand — maintaining consistent pressure across multiple outlets simultaneously while using significantly less energy than fixed-speed alternatives. The external pump is mounted alongside the tank for easy access and servicing.
The tank carries a 10-year warranty and the Esybox pump a 3-year DAB manufacturer warranty. WiFi connectivity via the H2D app allows remote monitoring and voice control via Google Home and Amazon Alexa. Please contact us for delivery timescales on this product.
Three tank-fed booster systems available from Anglian Pumping Services — all deliver 80 l/min at 3 bar. The key differences are tank capacity, pump technology, and intended use.

Powertank UTILITY 1000 — the commercial-grade choice. Rated to Fluid Category 4 for non-potable applications, robust Steadypress controller with integrated 8L pressure vessel. Higher price at £1,820 + VAT. No WiFi.
DAB Esybox + Esytank — smaller 480L modular tank (expandable on 3 sides), same DAB Esybox pump, £1,380 + VAT. Best where storage flexibility matters more than maximum capacity.

Frequently Asked Questions
Quick answers to common questions about the WaterBoost WB – Advant 1000 Esybox 2104110. For technical specifications, see the product details above; for sizing or installation advice, contact our team. If you have any other questions, we're happy to help.
What is a mains pressure boosting system?
A mains pressure boosting system increases the pressure and flow of water from the incoming mains supply into a property. It typically combines a pump and a storage or expansion tank, drawing water from the mains and delivering it to taps, showers and appliances at a stronger, more consistent pressure. They are used where the incoming mains is too weak to serve modern outlets reliably.
When do I need a mains booster pump?
You normally need a mains booster if static mains pressure is below 1.5 to 2 bar, if showers run weakly when other taps are open, or if combi boilers struggle to deliver hot water. Anglian Pumping recommends checking static pressure at the stop tap before specifying a system, then choosing a model rated for the number of bathrooms and outlets in the property.
What size mains booster do I need for my home?
Sizing depends on the number of bathrooms, the type of fittings and the static mains pressure. As a guide, a 1 to 2 bathroom property with combi boiler or single shower often needs 1.6 to 3 bar boost. A 2 to 3 bathroom property typically needs 3 to 4.5 bar with an integral break tank. Larger homes need a tank-and-pump system such as the DAB Esybox with Esytank or a Powertank set.
What is a water booster pump?
A water booster pump increases the pressure of an existing water supply to give stronger flow at taps, showers and appliances. It can be a small inline pump fitted to the incoming mains, or a larger pump and tank set that draws from a break tank to feed the whole house. Boosters do not create water – they raise the pressure of the water already coming in.
What is the difference between an inline booster and a tank-and-pump booster?
An inline booster connects straight onto the incoming mains and is limited to 12 litres per minute under UK water regulations – examples include the Salamander HomeBoost and WaterBoost WB-Compact. A tank-and-pump booster, such as the Grundfos Home Booster or DAB Esybox with Esytank, draws from a break tank and can deliver much higher flow rates for larger homes with multiple bathrooms.
What is a variable speed booster pump?
A variable speed booster uses an inverter to adjust pump speed in real time to match demand. It maintains constant pressure as outlets open and close, runs more quietly than a fixed-speed pump and typically saves up to 50 per cent of the energy a fixed-speed equivalent would use. The DAB Esybox, DAB Esybox Mini 3 and Grundfos Scala2 are common variable speed examples.
