How Do I Know When to Replace My Pool Pump?

A reliable pool pump keeps your water clean and clear—but even the best pumps wear out over time. Spotting the signs early can save you from breakdowns, costly repairs, or sky-high energy bills. Here’s how to decide if it’s time for a repair or a full upgrade.

Signs Your Pump Needs Replacing

Strange Noises
- Grinding, screeching, or rattling sounds (worn bearings or motor issues).
- Humming without starting (failed capacitor or seized motor).
Leaks or Cracks
- Water pooling under the pump (cracked housing or seal failure).
- Corrosion on metal parts (common in coastal areas with saltwater exposure).
Poor Performance
- Weak water flow from jets, even after cleaning the filter.
- Longer filtration times to clear debris.
Constant Repairs
- Replacing seals, motors, or impellers more than once a year.
- Rising energy bills due to inefficient operation.
Age
- Single-speed pumps: 5–8 years (if maintained well).
- Variable-speed pumps: 8–12 years (longer lifespan due to lower strain).

How to Test If Your Pump Is Failing

Check for leaks: Run the pump and inspect for drips around seals or housing.
Monitor pressure: A clean filter with low return flow indicates pump weakness.
Bucket test: Place a bucket of water under the pump—if it empties slower than usual, the impeller may be worn.
Listen: Unusual vibrations or noises during startup/shutdown.

When to Upgrade (Not Just Replace)

Switch to a variable-speed pump: Save up to 80% on energy costs (a smart move with Australia’s rising power prices).
Saltwater pool upgrades: Opt for corrosion-resistant materials if your old pump wasn’t salt-compatible.
Increased pool usage: Larger families or new water features (e.g., spas, waterfalls) may need a higher-capacity pump.

Choosing a Replacement Pump

Match horsepower (HP): Don’t oversize—stick to your pool’s volume and plumbing setup.
Prioritise energy efficiency: Look for ENERGY STAR ratings or solar-compatible models.
Check warranty: Make sure that your pump's warranty is LOCAL and comprehensive, just like the Water TechniX Pool Pump warranties.

Maintenance Tips to Extend Pump Life

Clean skimmer baskets weekly to prevent clogs.
Lubricate seals annually (or whenever you remove parts involving seals) with silicone grease.
Winterise in cooler regions: Drain water and cover if unused for months.
Avoid dry running: Ensure the pump primed before starting.
