Full Description

Tank overview

The DAB Esytank 500 is a 480-litre HDPE drinking water storage tank with a fully integrated Esydock docking station. It accepts the DAB Esybox booster pump directly, without tools or additional fittings.

Sold here as the tank only — for installations where the Esybox pump is already on site, or where a second tank is being added to expand capacity. The modular format allows auxiliary tanks to be coupled on any of three sides for additional storage, and the system supports up to four Esybox pumps wirelessly linked for duty-assist or duty-standby operation.

Supplied complete with all interconnecting pipework, suction pipe, foot valve, mains fill float valve, and overflow fitting.

Who this is for

Adding capacity to an existing system

If you already have an Esybox + Esytank installation and need more storage, an additional Esytank couples on any of three sides to expand total capacity. Use the appropriate coupling kit.

Building a twin-pump system

Pair this tank with two Esybox pumps for duty-assist (shared load) or duty-standby (one active, one redundant) operation. Wireless H2D linking handles pump coordination automatically.

Replacing an existing tank

If your existing Esytank needs replacing, this is the direct replacement — same dimensions, same Esydock, same connections. Your existing Esybox pump transfers across.

Looking for the complete system?

If you need both pump and tank, the Esybox + Esytank bundled system is the better choice — pump and tank supplied together, ready to install.

Key features

480-litre useable storage

Food-grade HDPE drinking water tank. Stores mains water during low-demand periods for delivery during peak draw.

Integrated Esydock

The Esybox pump docks directly onto the tank without tools — no plumbing required for the pump-to-tank connection.

Modular and expandable

Auxiliary tanks couple on three sides. Expand storage capacity in the future as demand grows or the property changes.

Twin-pump capable

Supports duty-assist (shared load) or duty-standby (active + redundant) configurations. Up to four Esybox pumps can be linked wirelessly.

Pre-fitted pipework

Built-in inlet and outlet connections, suction pipe with foot valve, mains fill float valve, and overflow fitting — supplied ready to commission.

Fits standard doorways

595 mm wide and 870 mm deep — dimensioned to pass through standard cellar and utility doorways for retrofit installations.

Top-mounted inspection lid

Routine cleaning and inspection without tools or part removal. The pump remains docked throughout.

Indoor fixed installation

Designed for utility rooms, cellars, garages, and plant rooms. Four base slots allow secure floor fixing.

DAB manufacturer warranty

Manufacturer warranty direct from DAB when purchased from Anglian Pumping, an authorised distributor.

Typical applications

Capacity expansion

Couple alongside an existing Esytank to add 480 L of storage. Useful when a property’s demand has outgrown its original installation.

Duty-standby system

Build a fail-safe system with a primary and secondary Esybox. If the primary fails or is taken offline, the secondary takes over automatically.

Duty-assist system

Two Esybox pumps share peak demand, doubling effective output for larger properties or light commercial sites with simultaneous high draw.

Tank replacement

Direct replacement for an existing Esytank. Same dimensions, same Esydock — your current Esybox pump transfers without modification.

Light commercial sites

Offices, hospitality, and small commercial premises requiring resilient pressure boosting with redundancy or expanded buffer storage.

Tall buildings — staged storage

Used as an intermediate buffer tank to divide pressure boosting across multiple zones or floors in larger buildings.

Frequently asked questions

Does this include the Esybox pump?

No — this is the tank only. The DAB Esybox booster pump is sold separately. If you need both pump and tank, the Esybox + Esytank bundled system is the better-value option.

Why is it called the Esytank 500 if the useable capacity is 480 litres?

The “500” is DAB’s product designation. The actual useable capacity is 480 litres once the float valve, overflow level, and inlet/outlet allowances are accounted for. We use 480 L in technical specifications and sizing calculations to give an accurate working figure.

What’s included in the box?

The Esytank 500 (480-litre HDPE storage tank), integrated Esydock docking station, suction pipe with foot valve, delivery pipe, mains fill float valve, overflow fitting, and all interconnecting pipework. The Esybox pump is not included.

How does it couple to an existing Esytank?

The Esytank’s modular design lets auxiliary tanks couple on any of three sides. A coupling kit links the tanks hydraulically so they fill and draw together as one volume. Get in touch if you need help confirming the right kit for your setup.

Can I run two Esybox pumps from this tank?

Yes — the Esytank supports up to four Esybox pumps wirelessly linked. Two pumps can run as duty-assist (sharing load at peak) or duty-standby (one active, the other taking over automatically if the primary fails). Each pump has its own dock position on the tank.

Is the tank WRAS approved?

The Esytank is manufactured from food-grade HDPE and is suitable for drinking water storage, but does not hold its own WRAS approval. Where a fully WRAS-approved tank is required by specification, the WaterBoost Advant range offers a UK-manufactured WRAS-approved alternative with a 10-year tank warranty.

Where can I install it?

The Esytank is designed for indoor fixed installation — typically a utility room, cellar, garage, or plant room. The 595 mm width fits through standard doorways. Four base slots allow secure floor fixing. Outdoor installation requires the optional DAB Esycover kit to weather-protect the docked Esybox.

How easy is maintenance?

A top-mounted inspection lid allows routine cleaning and checks without disturbing the pump or pipework. The Esybox docks and undocks from the Esydock without tools, so pump servicing is straightforward when needed.

What warranty is included?

Manufacturer warranty direct from DAB when purchased from Anglian Pumping, an authorised DAB distributor. Contact us if you need the current warranty term confirmed in writing for a specification.
