By utilising an optimised below ground footprint, the system delivers high throughput performance without requiring extensive excavation or disrupting existing structural foundations. Each tank is manufactured with an integrated anti-flotation flange to resist upward pressure from locations with a high water table.
Every Mini Drain Twin packaged system features a premium grade polyethylene chamber paired with two high performance submersible drainage pump capable of handling rapid fluid intake with complete reliability. The automated internal float switch mechanism guarantees autonomous operation, ensuring the sump evacuates efficiently as soon as fluid levels rise during heavy appliance use.
The Mini Drain Twin is not designed to handle domestic sewage, if you need a small pumping station to handle sewage please see our Mini Foul sewage pumping station.
Full installation instructions can be found in our accompanying Installation Guidelines.
Highlights
The premium polyethylene chamber structure features an integrated anti-flotation flange design to anchor the unit securely in high ground water conditions and prevent structural movement once concreted into position
Supplied as a complete install ready kit featuring internal pipework and an integrated non-return valve to prevent fluid backflow into the chamber after the pumps cycle off
The pre-wired submersible drainage pumps have vortex impellers to reliably clear wastewater over a maximum vertical lift height of three metres
A heavy duty pedestrian rated manhole cover is included as standard to allow safe installation flush with domestic driveways, garden paths, or patio areas without compromising site aesthetics
All of our pumping stations comply to British standards BS EN 12050-1:2001 and BS EN 752-6:1998 standards.
