Dual Basement Sump Pump

The Delta V3 Dual Sump & Pump Unit is designed to collect groundwater from a cavity drainage membrane system and pump it away to a suitable evacuation point. 

Groundwater enters via the membrane system and drainage channels and collects through the top opening of the sump or three 110mm pipe inlets. The water is then pumped via two powerful float-activated submersible pumps to mains drainage or another suitable outlet.

This basement pump station can only be used for collecting ground water. If you want to remove grey water or foul water from a toilet then you will need the Delta V3 Sump Pump for Foul Water.

Dual Sump Pump Installation

The Delta V3 Dual Sump Unit has been designed with ease of installation in mind. There are no specialist tools or skills required to install and all relevant adaptors are supplied.

The sump unit is delivered to site with all internal pipe work pre-installed. Only a simple screw on fitting is necessary to connect the pump. The unit is lowered into the excavation and all pipework and cable duct connections are made.

The pump station is filled with water to prevent flotation then back filled with 100mm concrete around the sump to form part of the floor slab. An access cover is set over the sump for maintenance purposes.

All the necessary adaptors are supplied to make it compatible with all pipework types.

A full range of installation and maintenance instructions are supplied with each Delta V3 Dual Sump Unit.
