Troubleshooting Pool Pump and Filter

A crystal-clear swimming pool is a true oasis during the hot summer months. Your pool pump and filter system are crucial to maintain that pristine water quality.

However, like any mechanical system, they can encounter issues over time. In this guide, we'll walk you through some common pool pump and filter problems and how to troubleshoot them effectively.

1. Insufficient Water Flow:

Symptoms: Weak jets, poor water circulation, and inadequate skimming.


  • Check the pump strainer basket for debris. Clean or replace it as needed.
  • Verify that the pool skimmer and pump intake are free from leaves and debris.
  • Inspect the pool filter. A dirty or clogged filter can restrict water flow. Clean or replace it according to the manufacturer's recommendations.
  • Examine the pump impeller for obstructions. Turn off the power and remove any debris if found.
  • Ensure that the pool pump is fully primed with water. If not, it can't efficiently move water through the system.

2. Unusual Noises:

Symptoms: Grinding, squealing, or banging sounds from the pump or filter.


  • Check for loose or damaged parts. Tighten any loose screws or bolts.
  • Inspect the pump motor and bearings. If they're making unusual noises, they might need lubrication or replacement.
  • Listen for cavitation sounds, indicating air is entering the system. Check for leaks in the suction line and correct any issues.
  • If you hear a rattling noise, it could be a damaged impeller. Replace it if necessary.

3. Pool Pump Not Starting:

Symptoms: The pump doesn't turn on or shuts off unexpectedly.


  • Verify that the power source is working. Check the circuit breaker and reset it if necessary.
  • Examine the pump motor for overheating. Overheating can cause the motor to shut off automatically. Allow it to cool down before restarting.
  • Check the pump's wiring for loose or damaged connections. Repair or replace damaged wires.
  • If the pump doesn't start, the motor capacitor or the motor itself may be faulty. Consult a professional for repairs or replacement.

4. Leaks:

Symptoms: Puddles of water around the pump or filter area.


  • Inspect all connections, including pipes, fittings, and valves. Tighten any loose connections or replace faulty seals.
  • Check the pump housing for cracks or damage. Replace the housing if needed.
  • Examine the filter tank for cracks or leaks. Replace the tank if it's compromised.

5. Pressure Issues:

Symptoms: High or low-pressure readings on the pool filter's pressure gauge.


  • High pressure may indicate a clogged or dirty filter. Clean or replace the filter cartridge or backwash a sand or DE filter per the manufacturer's instructions.
  • Low pressure might be due to an air leak in the suction line. Inspect the seals and connections, and fix any leaks you find.
