Emergency Breakdown

Even the best pump in the world can fail and when it does you need a fast, reliable contact to get the problem solved. The specialist service division of G M Treble has been established to help customers in their time of need. Our directly employed maintenance engineers are experts in fault finding and repair for a broad range of pumps.

Using the in-depth spares stock that we hold we can respond quickly to get sites back up and running as quick as possible. Where site repair is not possible, we can offer replacement pumps and off-site refurbishment of equipment.


Economic repair of equipment is essential in keeping costs down. Our engineers can strip and detail the work needed to allow clients to make an informed decision to repair or replace failed pumps.

Where a repair is the way forward we offer a complete service from assessment of the equipment, safe removal from the system, stripping down and replacement or refurbishment of all components. All repaired units are fully mechanically & electrically tested prior to return to the client.


G M Treble have the largest library of manufacturers documentation and technical information within the UK. We are proud to say that our information database is larger than most manufacturers retain for their own ranges.

Using this archive of information there is no one better placed to identify historic and older pump models and the spares or replacements required to solve customer problems.


Increasingly complex pump systems require precise set up to ensure maximum efficiency and optimum performance.

Our engineers are expert in commissioning all pump equipment and can help to work with a site to help prolong the life of the pumps, reduce noise from the system and ensure continued trouble free smooth operation.
