- Established 1975
- Trusted by thousands of customers
The WaterBoost WB-Advant 1000 Esybox Twin is the flagship WaterBoost system — a dual-pump, high-redundancy boosting system for demanding domestic and light commercial properties. A 1000-litre WRAS-approved UK-manufactured Advant tank (760mm W × 1350mm L × 1300mm H) pairs with two DAB Esybox pumps in a coordinated twin configuration, delivering 140 l/min at 3 bar and up to 6.5 bar maximum.
The two Esybox pumps communicate wirelessly via H2D technology — automatically balancing load and enabling true duty/standby operation. If one pump requires servicing, the other continues to run without interruption. Both pumps include WiFi via DConnect, Google Home and Alexa voice control, running at 43 dB(A) each. All interconnecting pipework included — no site assembly required.
The UK-manufactured tank carries an outstanding 10-year warranty and each DAB Esybox a 3-year warranty. Delivery is typically 1–2 working days.

Three high-flow 1000L systems. The WB-Advant 1000 Esybox Twin sits in the middle on price — less expensive than the Powertank Twin yet delivering more pressure capability, WiFi, H2D load balancing, true duty/standby redundancy, and a named 10-year tank warranty. The Powertank Plus offers the lowest price at 138 l/min with a single pump. The Powertank Twin reaches 160 l/min with Cat 4 compliance.
WB-Advant 1000 Esybox Twin — the best choice for high-flow potable water boosting with built-in redundancy at £2,461 + VAT. 140 l/min, 6.5 bar max, true H2D duty/standby, WiFi and voice control, 43 dB(A), named 10-year tank and 3-year pump warranties. 1–2 day delivery. The right choice where supply continuity and high performance are both required.
Powertank UTILITY 1000 Plus — choose for Fluid Category 4 compliance where a single pump is acceptable, at £2,105 + VAT. 138 l/min, variable speed, but no redundancy, no WiFi, max pressure not stated.
Powertank UTILITY 1000 Twin — choose for Fluid Category 4 compliance with twin pump redundancy and 160 l/min peak flow. At £3,040 + VAT it is £579 more than the WB-Advant Twin — with lower max pressure (5 bar), no WiFi, and no named warranties.

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.
