Frequently asked questions

Can I connect two or more of these tanks together for extra capacity?
Yes, the 4 inch connections let you link additional tanks together using standard 4 inch drainage pipe if 500 litres isn't enough on its own.

What does the underground water filter option add?
Choosing the large underground water filter option fits an inline filter to the tank at the point of manufacture, so incoming water is filtered before it collects.

What does the external tap system option add?
Choosing the external tap system option fits a tap connection to the tank, so you can draw water off without lifting the lid.

Does this tank take standard UK drainage pipe?
Yes, both connections are sized for UK standard 4 inch (110mm) pipe fittings, with a 1 inch BSP bottom outlet for smaller take-offs.

Can the extended neck be cut to depth?
Yes, it's supplied with a 500mm extended neck that can be cut down to match your excavation depth.

Is this water safe to drink?
No, this tank doesn't carry potable or WRAS certification, so it's intended for general non-drinking water storage such as garden or vehicle-washing use rather than a drinking supply.

How is the tank built and what's the warranty?
It's rotationally moulded as a single-piece MDPE shell for a strong, leak-free tank, backed by a 10-year warranty against manufacturing defects.
