A building maintenance company required a new pump station to be installed in an existing concrete chamber. The station would need to handle a low flow rate from plant room spillage and occasional wash down. Due to the low level of the chamber inlets, the control switches would need to be set carefully to ensure the pumps operated only when required.

The Edincare Engineer’s thorough survey also revealed that the existing rising main which connected the pump station to the gravity drain was not suitably pressure rated.


• An Edincare MagnaGrand™ IP twin pump pumping station was installed in the concrete sump, along with a cable management system.
• A twin pump control panel was also installed and control levels were set with careful attention paid to the low level inlets. A new pressure rated rising main was installed that discharged into the gravity drain.


• Full engineering survey before installation allowed us to identify the issues with the concrete sump installed and develop a design which addressed them.
• After installation the pump station was fully wet tested to ensure the low level inlets into the chamber would not surcharge and the pumps did not air lock.
• Electrofusion pipework was used for the replacement rising main to increase reliability.






On any installation it’s very important that the float switches are set correctly.

A pump which is operated too frequently due to poorly set switches is subject to unnecessary wear, shortening its service life significantly.

Floats should also be set to switch off at the correct level to prevent the pumps drawing in air which can cause air locking. Air locking occurs when there is air between the pump and the checkvalve of the discharge line. This acts like a closed valve.

Edincare thoroughly wet tests all installations to ensure that pumps operate only when required.
