Pumps are essential components in industrial, commercial, and residential systems. Whether used for water transfer, circulation, or process applications, reliable pump performance keeps operations running smoothly. However, pumps do occasionally encounter issues that can reduce efficiency, increase energy consumption, or cause unexpected downtime.
Understanding common pump problems and how to fix them can help businesses and facility managers extend the life of their equipment, reduce maintenance costs, and maintain smooth operation. This article explains typical pump issues and provides expert solutions that align with best practices used by professionals, including those at Tsunami Pump.
Key Takeaways
- Pumps can encounter operational issues due to mechanical wear, improper installation, or environmental factors.
- Common problems include loss of flow, vibration, overheating, and leakage.
- Proper diagnosis and corrective actions can prevent costly downtime.
- Regular maintenance and system checks improve reliability and pump lifespan.

1. Loss of Flow / Jammed
Q: Why is my pump jammed and not running at all?
Symptoms:
- Lower than expected flow rate or pressure
- Pump struggles to deliver required capacity
- Pump not running at all
Common Causes:
- High possibly caused by worn impeller or internal components
- This may be caused by a jammed mechanical seal or low motor power.
2. Excessive Vibration and Noise
Q: Why is my pump very noisy?
Symptoms:
- Loud humming, rattling, or grinding sounds
- Noticeable vibration around the pump
Common Causes:
- If the noise is coming from the pump itself, it could be due to the bearing, mechanical seal, middle section, impeller or controller copper valve.
- The pump may be placed directly on a platform without a foam base underneath, causing vibration and increased noise. Install a foam pad or rubber mat under the pump to reduce noise and stabilize it during operation.
3. Motor Failure (Red Light)
Q: Why does my pump show failure (red light)?
Symptoms:
- Pump not running at all
- With a red light appears beside the “Failure” indicator
Common Causes:
- It may be due to air lock problem. During a water disruption, if you forgot to switch off your pump, or if you turned it on immediately after the water supply resumed without waiting for the tank to fully refill, this may occur. To solve this, refer here.
- This may be caused by insufficient water supply, as the Home Booster Pump (CMH, CMF, CMS Series) requires a stable and adequate water source to function correctly.
4. Water Leakage
Q: Why is my pump leaking?
Symptoms:
- Visible fluid escaping from pump housing
- Visible fluid escaping from piping
Common Causes:
- This may be caused by a mechanical seal malfunction, controller back assembly issue or aging gasket.
- This may also be caused by improper piping installation at the inlet/outlet.
5. Pump Running Non-stop / Start and Stop Frequently
Q: Why does my pump run non-stop? / Why does my pump start and stop frequently?
Symptoms:
- Pump operates non-stop
- Pump frequently start and stop within short period of time (intermittent)
Common Causes:
- If the water pump is newly installed with PVC piping, you may notice traces of glue in the controller copper valve (refer to the photo below).
- There may be a leak in the pump system. Kindly close the outlet ball valve and observe: if the pump stops, it is most likely leaking from the piping; if it continues, it is likely from the pump controller.
