5 Warning Signs your pump might be failing

Most pump failures don’t happen overnight, they usually give off subtle (and not so subtle) warning signs before things go pear shaped.
5 warning signs of a failing pump

Spotting these early signs can help you avoid the unexpected shutdowns, water damage and costly emergency repairs, so here is a list we’ve compiled at Sydney Central Pumps to keep an eye (and ear) out for the following:


Noises you haven’t heard before
A well running pump should hum quietly in the background. If you hear banging, grinding, high-pitched squeals or feel unusual vibrations, this could be a misalignment, worn bearings or motor issues.


Visible Rust or leaks
Having rusk on components or visible water leakage may seem minor but can be signs of a bigger internal problems. Leaks also reduce pressure and efficiency, leading to performance issues.


Inconsistent Water Pressure
If you are hearing complaints about weak or inconsistent pressure, particularly during peak usage times, your pump might be struggling to keep up. This can point to blockages, wear and tear or pump sizing issues.


Frequent Electrical Trips

Power tripping without a clear reason? this might be your pump drawing to much current due to internal fault or overload. This is often a red flag that shouldn’t be ignored (not like your ex partners weird habits)


Manual Resets more often than not
If your system is asking for constant manual resets, it’s trying to tell you something, it’s best to not wait until it completely fails.


If some some of these signs seem relatable to you, it is time to get a health check on your pumps. You can contact the Sydney Central Pumps team to gain a clear diagnosis on what your next steps are. We are Sydney’s number one experts in Pump System Servicing and Maintenance.
