A quick guide to submersible pump care

A submersible pump is a handy device to own – whether you use it for drainage, sewage treatment, seawater handling or other application. However, like any piece of electro-mechanical equipment, a submersible pump requires regular maintenance in order to ensure optimum performance.

These are some of the main areas for routine inspection:

Inlet screen

This can become clogged with debris such as leaves, stones and mud and should be checked and cleared every quarter.


If the float becomes obstructed it may not activate the pump when required – or the pump could run dry. Ensure the float can move freely so that it turns on automatically. If the float is unimpeded yet the pump doesn’t automatically activate, test the power connection and float switch for faults.

Discharge line

This can become clogged up and may freeze during winter. Unblock the air vent hole in the line if necessary.

If you have a submersible pump malfunction and can’t diagnose the fault, give Gibbons a call. Our engineers repair most pump types and we can collect and deliver within a 50-mile radius of our workshop free of charge.

Or if your pump is beyond repair, we’re an approved stockist of industry-leading Lowara pumps. We offer same-day worldwide dispatch and outstanding technical support to ensure you get the most from your equipment.

    A great guide, we recently worked on a project to supply five high temperature submersible pumps [ ] and I can not stress how important caring for them is! If you want them to last and work for as long as they should, then you need to ensure they are cleaned regularly!
