Why Choose CPD Waste Water for Your Grundfos Pump?

Grundfos pumps are built to last, but when they do fail they need an engineer who understands the specific construction and fault modes of each series. Our team has extensive experience with Grundfos wastewater pumps and carries common spare parts including impellers, seals, and float switches. We can often repair a failed Grundfos pump on the same visit, getting your system back online quickly.

Grundfos Pump — Frequently Asked Questions

How long do Grundfos sewage pumps last?

A well-maintained Grundfos sewage pump typically lasts 10–15 years. Regular servicing and prompt attention to any alarms or performance changes will maximise the lifespan of your pump.

My Grundfos pump is running but not pumping — what's wrong?

This is usually caused by a blocked or worn impeller, or a partially blocked discharge pipe. Call us on 01252 985722 — we can diagnose and resolve this quickly.

Can you repair a Grundfos pump or does it need replacing?

In most cases we can repair a failed Grundfos pump. Motor burnout, seal failure, and impeller damage are all repairable. We'll always give you an honest assessment of whether repair or replacement is the better option.

Do you cover emergency Grundfos pump failures at weekends?
