7 Warning Signs Your Pool Equipment Needs Attention (Before It Fails)

Pool equipment rarely fails without warning. In most cases, there are early signs something isn’t quite right — a new noise from the pump, pressure rising faster than usual, or water becoming harder to keep clear. Catching problems early can often prevent expensive repairs, reduce downtime, and help avoid the pool turning green at the worst possible time.

Here are 7 common warning signs we regularly see across Perth pools, and what they usually mean.

1) Your Pool Pump Is Louder Than Normal

A healthy pool pump should run with a smooth, consistent sound. If it suddenly becomes louder, starts rattling, grinding, or changes tone, it may indicate:

• Worn motor bearings

• Air entering the system

• A blockage causing strain on the pump

• Reduced water flow

What to do:

Don’t ignore unusual pump noise. Early diagnosis can often prevent complete pump failure and more costly repairs.

2) Weak Suction or Low Flow at the Skimmer

If your skimmer box isn’t pulling debris like it used to, it could point to:

• A clogged skimmer basket

• A dirty filter

• A blocked suction line

• A pump issue

• Incorrect valve settings

Low circulation can also reduce filtration efficiency and make pool water harder to balance.

What to do:

Check and empty baskets first. If low flow continues, it’s worth having the system inspected.

3) Filter Pressure Keeps Rising Quickly

Pool filter pressure will naturally increase as debris is collected. However, if pressure climbs rapidly soon after cleaning or backwashing, it may indicate:

• Dirty or worn filter media

• Circulation restrictions

• Poor water flow

• The system working harder than normal

What to do:

Monitor your filter pressure regularly. Sudden or frequent pressure increases usually mean something needs attention.

4) Your Pool Water Is Harder to Keep Balanced

If the water is suddenly becoming cloudy, dull, or drifting out of balance despite adding chemicals, the issue may not be chemistry alone. Poor circulation or filtration can prevent chemicals from distributing properly throughout the pool.

Common signs include:

• Cloudy water

• Increased chemical usage

• Algae returning quickly

• Inconsistent chlorine readings

What to do:

Treat it as a potential equipment or circulation issue, not just a water chemistry problem.

5) Air Bubbles in the Pump Basket or Return Jets

Occasional small bubbles can be normal, but ongoing air in the system often points to:

• A suction-side air leak

• Low pool water level

• A worn O-ring or seal

• Cracked fittings or pipework

Air leaks reduce efficiency and place additional strain on equipment over time.

What to do:

Check the pool water level first. If bubbles persist, arrange an inspection before the issue worsens.

6) Leaks, Damp Areas, or Corrosion Around Equipment

Any visible water around your equipment area deserves attention. Even small leaks can eventually lead to:

• Pump or motor damage

• Rust and corrosion

• Electrical issues

• Premature equipment failure

What to do:

If you notice dripping water, damp concrete, staining, or corrosion around the equipment pad, it’s best to address it early.

7) Your Salt Chlorinator Isn’t Keeping Up

For saltwater pools, declining chlorine production is often one of the first signs of equipment problems.

You may notice:

• Chlorine levels dropping more frequently

• The chlorinator cell requiring constant cleaning

• Water quality becoming less stable

• Increased algae or cloudy water

This can indicate:

• A chlorinator cell nearing the end of its lifespan

• Low water flow

• Incorrect settings

• Early system faults

What to do:

A professional equipment inspection and water test can usually identify the cause quickly.

A Simple Rule: If Something Changes, It’s Worth Checking

Most pool owners notice the warning signs first — a new sound, a change in water clarity, or unusual equipment behaviour. Trust that instinct. Small pool equipment problems are usually far cheaper and easier to fix when caught early.
