What is the WB-Advant 2000 Esybox Twin?
The WaterBoost WB-Advant 2000 Esybox Twin is the flagship of the WaterBoost range — combining two linked 1000-litre WRAS-approved UK-manufactured Advant tanks (2000 litres total) with two DAB Esybox variable speed pumps in a coordinated twin configuration. Designed for very high-demand domestic and light commercial properties where both large stored volume and uninterrupted supply continuity are required.
The two Esybox pumps communicate wirelessly via H2D technology — automatically balancing load with no extra wiring and enabling true duty/standby operation. Combined output is 140 l/min at 3 bar with each pump capable of 6.5 bar maximum. If one pump requires servicing or develops a fault, the other continues to supply the property without interruption.
Both pumps include WiFi via the DConnect app, Google Home and Alexa voice control, and run at a quiet 43 dB(A) each. All interconnecting PVC pipework is supplied. Both tanks carry a 10-year warranty and each Esybox a 3-year DAB warranty. Please contact us for delivery timescales.
What’s included
Two DAB Esybox booster pumps
Two external variable speed Esybox pumps linked via H2D — 80 l/min each (140 l/min combined), 6.5 bar max, 43 dB(A) each. WiFi/DConnect/Google/Alexa on each. True duty/standby. 3-year DAB warranty per pump.
Two 1000-litre Advant tanks
Two WRAS-approved 1000L UK-manufactured Advant tanks. Primary pre-fitted with By-law 30 kit and ¾” ball float valve; secondary linked via base PVC. 100% rust-proof, 10-year warranty each.
Twin pump mounting frame
Stainless steel mounting frame to support both Esybox pumps side by side alongside the tank assembly. All pump-to-frame fixings supplied.

Tank-to-tank linking pipework, twin-pump suction manifold, and combined discharge. Pre-cut and ready to assemble. No site fabrication required.
Key features
2000L combined WRAS storage
Twin-linked 1000L Advant tanks — the largest reservoir in the WaterBoost range. Two full days of normal household demand on stored buffer alone.
140 l/min @ 3 bar — twin Esybox
Two coordinated DAB Esybox pumps deliver a combined 140 l/min — enough for the most demanding simultaneous-demand scenarios.
True duty/standby redundancy
H2D links both Esybox pumps wirelessly — if one is taken offline for servicing, the other continues to supply without interruption.
WiFi, H2D, Google and Alexa
Both pumps connect via DConnect and H2D — remote monitoring, intelligent load balancing, voice control via Google Home and Alexa.
10-year tank warranty
Both UK-manufactured WRAS Advant tanks carry a 10-year warranty, plus 3-year DAB manufacturer warranty on each Esybox.
43 dB(A) — exceptionally quiet
Each Esybox runs at 43 dB(A) — outstanding for an 80 l/min pump. Even with both pumps active the system remains very quiet.
6.5 bar maximum pressure
6.5 bar maximum from each Esybox — the highest in the WaterBoost range. Supports demanding hot water systems and large outlet counts.
Independent dual-duty option
Via H2D the two pumps can run as two independent duty pumps on separate circuits — for example domestic on one, irrigation on the other.
Typical applications
High-demand domestic properties
Large homes with many bathrooms running concurrently — 140 l/min handles the most demanding simultaneous-use scenarios.
Hospitality and B&B
Small hotels, guesthouses, holiday parks — where water supply continuity is critical and a pump failure cannot be allowed to interrupt service.
Very slow mains + high demand
The combination of 2000L storage buffer with 140 l/min peak output covers properties where both mains supply and peak demand are challenging.
Light commercial premises
Offices, workshops, small commercial sites requiring continuity of supply and large stored volume to ride through mains restrictions.
Independent dual circuits
Domestic supply on one pump, irrigation or commercial circuit on the other — each maintaining its own pressure independently via H2D.
Remote monitoring critical
DConnect, H2D, Google and Alexa — essential where the property is managed remotely or part of a let portfolio.
How it compares
Three twin-pump options at the top of the WaterBoost range. The Advant 2000 Twin offers the largest stored volume combined with high-flow redundancy. The 1000 Twin gives the same flow and redundancy in a more compact footprint. The Powertank Twin reaches 160 l/min with Cat 4 compliance but lacks WiFi and named warranties.

Frequently asked questions
How quickly is it delivered?
Please contact us via WhatsApp or phone for delivery timescales — the two-tank twin-pump format requires confirmation of access and offload arrangements before dispatch.
How does the duty/standby redundancy work?
The two Esybox pumps connect wirelessly via H2D (Hydraulic to Digital) technology — no inter-pump wiring needed. In duty/standby mode, one pump handles demand while the other is on standby, ready to take over immediately if the duty pump is taken offline or develops a fault. Switchover is automatic and seamless — the supply to the property is not interrupted.
How are the two tanks linked?
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 fill and draw evenly. The twin-pump suction manifold draws from the combined assembly.
Can the two pumps run independent circuits?
Yes — via H2D the two Esybox pumps can be configured as two independent duty pumps serving separate circuits. For example one pump on the domestic hot water circuit, the other on irrigation or a separate commercial circuit — each maintaining its own pressure setpoint independently.
When does the 2000 Twin make sense over the 1000 Twin?
Both deliver 140 l/min with H2D duty/standby. The 2000 Twin adds 1000L extra storage and roughly doubles the footprint width. Choose the 2000 Twin where the mains fill rate is very slow, peak demand runs for extended periods, or the source is occasionally unavailable (boreholes, restricted mains). If 1000L storage is sufficient, the WB-Advant 1000 Esybox Twin is the more compact choice.
What is the total footprint?
Approximately 1520mm wide × 1350mm long × 1300mm high for the linked tank assembly, plus the twin Esybox pump frame mounted alongside. Designed for garages, plant rooms, and outbuildings — each tank passes through standard doorways individually at 760mm wide.
What warranties are included?
10 years on each Advant storage tank, and 3 years DAB manufacturer warranty on each Esybox pump — when purchased from Anglian Pumping Services.

Frequently Asked Questions
Quick answers to common questions about the WaterBoost WB – Advant 2000 Esybox Twin 2104410D. 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.
