90L Basement Groundwater & Dewatering Pump System

Ideal for Basements, Cellars & Flood-Prone Areas

Protect your basement or cellar from groundwater and flooding with our 90L Groundwater & Dewatering Pump System. Designed for residential use, this compact and fully automatic system safely removes excess water when gravity drainage isn’t possible.

Once installed, the pump works automatically in the background – switching on only when water levels rise and turning off when the job is done.

Why Choose This Pump System?

✅ Compact & Space-Saving
The 90L sump chamber is designed to fit into smaller basement spaces and requires minimal groundwork.
Chamber size: 460mm (D) x 560mm (H)

✅ Reliable Pumping Performance
Capable of pumping up to 174 litres per minute with a vertical lift of 6.2 metres, making it ideal for domestic basement and cellar installations.

✅ Fully Automatic Operation
The system can be left switched on at all times. It only runs when needed, helping to reduce energy use and wear on the pump.

✅ More Reliable Float Switch
Fitted with an arm-style float switch, which is far more dependable and longer-lasting than traditional cable float switches.

✅ Prevents Backflow
A non-return valve is included to stop water flowing back into the chamber once it has been pumped away.

✅ High-Quality Pipework Included
Supplied with 1¼” Class C high-pressure PVC pipework and fittings, designed to improve flow rates and reduce vibration compared to standard waste or MDPE pipe.

✅ Built for Long-Term Use
The sump chamber is manufactured from high-quality moulded polyethylene and includes an anti-flotation device for added security in high groundwater conditions.
