The WaterBoost WB-Advant 1000 Variable Speed is a compact, self-contained high-performance boosting system for larger domestic and light commercial properties. A 1000-litre WRAS-approved UK-manufactured Advant tank (760mm W × 1225mm L × 1200mm H) houses the DAB Esybox Diver — a fully integrated variable speed pump that sits submerged inside the tank — delivering up to 100 l/min maximum at 5 bar maximum pressure, with WiFi and DConnect app.

The internal pump design creates a truly self-contained system — no external pump unit needed alongside the tank. The mains connects directly via the pre-fitted ¾” ball float valve. All interconnecting pipework supplied — no site assembly required. Designed for garages, plant rooms, and utility spaces where a clean, minimal footprint is important.

The UK-manufactured tank carries an outstanding 10-year warranty and the DAB Esybox Diver a 3-year warranty. Delivery is typically 1–2 working days.

Product overview

The WaterBoost WB-Advant 1000 Variable Speed is a compact, self-contained boosting system for high-demand domestic and light commercial applications. A 1000-litre WRAS-approved UK-manufactured Advant tank (760mm W × 1225mm L × 1200mm H) houses the DAB Esybox Diver — a fully integrated variable speed pump that operates submerged inside the tank — delivering up to 100 l/min maximum at 5 bar maximum pressure, with WiFi via the DConnect app.

The internal Diver pump means no external pump unit is required alongside the tank — the entire system is contained within the Advant tank’s own footprint. The mains connects directly via the pre-fitted ¾” ball float valve. All interconnecting PVC pipework is supplied — no site assembly required. Designed for garages, plant rooms, and utility spaces where a self-contained installation is preferred.

The UK-manufactured tank carries an outstanding 10-year warranty and the Esybox Diver a 3-year DAB warranty. Delivery typically 1–2 working days.

Need higher flow or redundancy?

The WB-Advant 1000 Esybox Twin (£2,461 + VAT) uses two Esybox pumps externally for 160 l/min peak and full built-in redundancy.

Typical applications

High-demand domestic and light commercial

Up to 100 l/min with 1000L buffer — ideal for multiple bathrooms, B&Bs, holiday lets, and small commercial premises with demanding simultaneous demand.

Where footprint is critical

Internal pump design means the system occupies only the tank’s own footprint — no additional space needed for an external pump alongside.

Extremely slow mains supply

1000L fills overnight on even the most restricted trickle — ready for high peak demand without interruption throughout the day.

Garages and plant rooms

The 760mm W × 1225mm L × 1200mm H Advant format is designed for garage and plant room installation with dedicated floor space.

Long-term infrastructure investment

10-year tank warranty backed by named DAB pump warranty — a serious long-term installation for properties with a permanent pressure challenge.

Remote monitoring via app

DConnect WiFi app for remote system monitoring and pressure management — useful for commercial premises or properties managed remotely.

How it compares

Three large-capacity variable-speed systems. The WB-Advant 1000 Variable Speed is the cheapest, has the most storage, the highest peak flow (100 l/min), WiFi, a named 10-year tank warranty, and a compact internal pump design — at £1,362.75 vs £1,495 and £1,820 for the Powertank alternatives. Both Powertank options offer Fluid Category 4 compliance for installations where this is a specific requirement.

Which should I choose?
WB-Advant 1000 Variable Speed — the best-value choice at £1,362.75 + VAT. Cheapest of the three, highest peak flow (100 l/min), most storage (1000L), WiFi, 10-year tank warranty, named pump warranty, and the most compact footprint thanks to the internal Diver pump. 1–2 day delivery. The right choice for potable water applications.
Powertank UTILITY 750 Variable — choose for Fluid Category 4 compliance where 750L storage is sufficient. 80 l/min, 8L integral pressure vessel, external pump. £1,495 + VAT.
Powertank UTILITY 1000 Variable — choose for Fluid Category 4 compliance with 1000L storage. Same 80 l/min performance as the 750L version, external pump, no WiFi. At £1,820 + VAT it is £457.25 more than the WB-Advant with less peak flow and no named warranties.

Frequently asked questions

How much does it cost and how quickly is it delivered?

£1,362.75 + VAT (£1,635.30 inc VAT). Delivery is typically 1–2 working days. Contact us via WhatsApp or phone to confirm availability before ordering.

What is the DAB Esybox Diver and how does it differ from the standard Esybox?

The Esybox Diver is a submersible version of the DAB Esybox system — designed specifically to operate submerged inside a water storage tank. Unlike the standard Esybox (which sits externally alongside the tank), the Diver is installed inside the tank, making the system entirely self-contained within the tank’s own footprint. Performance is up to 100 l/min max at 5 bar maximum, with WiFi via the DConnect app. The standard WB-Advant 1000 Esybox (£1,360 + VAT) uses the external Esybox (80 l/min, 6.5 bar, 43 dB(A), H2D and Google/Alexa) for buyers who prefer pump accessibility from outside the tank.

How is the pump serviced if it’s inside the tank?

The Esybox Diver is accessed via the Advant tank’s inspection lid at the top of the tank. Servicing requires the tank to be isolated and the water level reduced to access the pump. This is a straightforward process for a qualified engineer. If external pump accessibility without tank involvement is important to you, the WB-Advant 1000 Esybox (£1,360 + VAT) uses an external pump for the same price.

What is the difference between this and the WB-Advant 1000 Esybox?

Both use the same 1000L Advant tank with 10-year warranty at a very similar price (£1,362.75 vs £1,360 + VAT). The key differences are the pump type and position. This system uses the Esybox Diver (internal) — up to 100 l/min max, 5 bar max, WiFi/DConnect, compact self-contained footprint. The WB-Advant 1000 Esybox uses the external Esybox — 80 l/min @ 3 bar, 6.5 bar max, 43 dB(A), WiFi/H2D/Google/Alexa. Choose the Diver (this product) if footprint compactness and 100 l/min peak flow are priorities; choose the Esybox if pump accessibility and 6.5 bar max pressure matter more.

What warranties are included?

10 years on the WRAS Advant tank and 3 years DAB warranty on the Esybox Diver pump, when purchased from Anglian Pumping Services.
