What is the WB-Advant 2000 Esybox?
The WaterBoost WB-Advant 2000 Esybox is the largest-storage single-pump system in the WaterBoost range — engineered for properties with very slow mains supply or sustained peak demand. It combines two linked 1000-litre WRAS-approved UK-manufactured Advant tanks (2000 litres total) with the market-leading DAB Esybox variable speed pump, supplied fully plumbed and ready to connect.
The two tanks are linked at the base by factory-supplied PVC pipework — water level equalises naturally so both tanks fill and draw evenly via a single mains feed. The externally-mounted Esybox delivers 80 l/min at 3 bar and up to 6.5 bar maximum, continuously varying its speed to match demand and using significantly less energy than fixed-speed alternatives.
WiFi connectivity via the DConnect app and H2D technology enables remote monitoring, pressure adjustment, and voice control via Google Home and Amazon Alexa. The tanks carry an outstanding 10-year warranty and the Esybox a 3-year DAB manufacturer warranty. Please contact us for delivery timescales.

Key features
2000L combined WRAS storage
Twin-linked 1000L Advant tanks deliver an exceptional reservoir buffer for properties with very slow mains fill or sustained peak demand.
Variable speed — 80 l/min @ 3 bar
DAB Esybox adjusts speed to match demand — constant pressure across every outlet, up to 50% energy saving over fixed-speed systems.
WiFi and voice control
DConnect app for remote monitoring and pressure adjustment. Google Home and Amazon Alexa compatible — say “Hey Google, power shower”.
43 dB(A) — whisper quiet
Water-cooled motor in sound-absorbing housing. Quiet enough for garages and plant rooms close to living areas.
External pump — easy servicing
The Esybox sits alongside the tank assembly — fully accessible for inspection, adjustment, and replacement without disturbing either tank.
10-year tank warranty
Both UK-manufactured WRAS Advant tanks carry a 10-year warranty as standard, plus 3-year DAB manufacturer warranty on the Esybox.
Linked-tank fill balance
Tanks are linked at the base via PVC — water level equalises naturally so both fill and draw evenly. No twin-float complexity.
Single mains inlet
Only one mains feed required — connected to the pre-fitted ¾” ball float valve on the primary tank. Simpler than separate tank arrangements.
Typical applications
Very slow mains fill rate
Where mains fills at less than 10 l/min, 2000L overnight storage provides the buffer needed to meet morning peak demand.
Sustained-demand properties
Large homes, B&Bs, holiday lets, small hotels — anywhere peak demand runs for hours rather than minutes.
Rural and off-grid
Stores water from boreholes, wells, or restricted mains and delivers it on demand at consistent pressure. The 2000L reserve covers periods when the source is unavailable.
Light commercial premises
Offices, workshops, small commercial sites requiring large stored volume with reliable boosted delivery across the working day.
Water Regulations compliance
The break tank arrangement ensures full compliance where direct mains boosting is not permitted by the water undertaker.
Irrigation and wash-down
Large reservoir capacity suits irrigation systems, agricultural wash-down, and similar applications with intermittent high-volume draw.
How it compares — WB-Advant 2000 vs 1000 vs 2000 Twin
Three tank-fed boosting options. All use the DAB Esybox pump. The differentiators are storage capacity, footprint, and pump configuration.

Flow rates are dependent on incoming mains supply. The Esybox pump cannot connect directly to the mains — the tanks act as the break tank.
Frequently asked questions
How quickly is it delivered and how is it shipped?
Please contact us via WhatsApp or phone for delivery timescales — the two-tank format requires confirmation of access and offload arrangements before dispatch.
How are the two tanks linked together?
The two 1000L Advant tanks are placed side by side and joined at the base with the supplied PVC linking pipework. Water level equalises naturally — both tanks fill and draw evenly without any twin-float arrangement or balancing valves.
Do I need two mains feeds?
No — only one mains feed is required. It connects to the pre-fitted ¾” ball float valve on the primary tank, and the secondary tank fills via the base linking pipe. One mains connection, one float, two tanks of storage.
When does the 2000 make sense over the 1000?
Three scenarios. Very slow mains fill — if your mains delivers less than around 10 l/min, 2000L overnight storage covers morning peak even if the tank is being depleted faster than it fills. Sustained-demand premises — B&Bs, holiday lets, multi-occupancy properties where peak draw lasts hours rather than the typical 30-minute morning/evening spikes. Source outages — properties on boreholes or wells where the source occasionally becomes unavailable; 2000L is a meaningful reserve. If none apply, the standard WB-Advant 1000 Esybox is more economical with a smaller footprint.
Does the 2000 give more flow than the 1000?
No — flow at the tap is identical. Both use the same single DAB Esybox at 80 l/min at 3 bar. The 2000 has twice the stored volume — meaning the system can sustain that flow for longer between mains refills. If higher peak flow is needed, choose the WB-Advant 2000 Esybox Twin (140 l/min combined).
What is the total footprint?
Approximately 1520mm wide × 1350mm long × 1300mm high for the linked tank assembly, plus the Esybox pump mounted alongside. The format is designed for garages, dedicated plant rooms, and outbuildings — it will not fit through a standard single-tank doorway as one piece (the tanks pass individually at 760mm wide each).
Are both tanks WRAS approved?
Yes — both tanks are UK-manufactured from WRAS-approved polyethylene and are fully compliant for potable water storage. Each tank carries the 10-year warranty independently.
What warranties are included?
10 years on each Advant storage tank, and 3 years DAB manufacturer warranty on the Esybox pump — when purchased from Anglian Pumping Services.

Frequently Asked Questions
Quick answers to common questions about the WaterBoost WB – Advant 2000 Esybox 2104110D. 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.
