Does your pool need servicing or repairs?

There’s nothing like a relaxing dip in a sparkling pool or lounging poolside with your favourite book. But when maintenance issues arise, that tranquil scene can quickly turn stressful - and costly. Even minor problems, if ignored, can escalate into significant damage and hefty repair bills.

A neglected pool isn’t just an eyesore - it can pose serious health and safety risks. Algae, bacteria, and malfunctioning equipment can turn your backyard oasis into a hazard zone. Staying on top of maintenance not only preserves your pool’s functionality but also keeps it looking pristine.

Common Pool Issues You Shouldn’t Ignore

Here are some of the most frequent problems pool owners face. Catching them early can improve performance, prevent safety hazards, and even extend your pool’s lifespan.

1. Green Algae Growth

If your pool water looks murky or you see slippery green patches on the surfaces, algae is likely the culprit. Caused by low chlorine levels or poor water balance, algae blooms are both unsightly and dangerous.

The Fix: Your pool engineer will scrub the walls and floor to loosen algae, shock the pool with chlorine, and run your filtration system continuously until the water clears. Regular water testing is key to prevention.

2. Broken Pool Lights

A malfunctioning light isn’t just annoying - it can be a serious electrical hazard. Water and electricity are a dangerous mix, so proceed with caution.

Safety Tip: If attempting a DIY replacement, always turn off power at the main breaker. Better yet, hire a licensed professional - especially if the light keeps failing, as this may signal deeper electrical issues.

3. Bulging Pool Walls

Seen more often in fibreglass or liner pools, bulging walls can result from incorrect installation or sudden changes in water pressure - especially after draining.

Why It Matters: Left untreated, bulges can cause leaks or structural damage. A long-term fix often involves draining the pool and replacing backfill with stable gravel to better support the walls.

4. Inadequate Pool Heating

Nothing spoils a swim like freezing water. Heating issues often trace back to a blocked heat exchanger, faulty thermostat, or broken pressure switch.

Maintenance Must: Have your gas heater inspected yearly by a Gas Safe registered engineer. Regular service ensures safety, efficiency, and warm swims all season.

5. Noisy or Leaking Pump

Your pool pump should have a steady, low hum. If it starts making odd noises, leaking, or accumulating puddles, something’s off.

What To Do: Turn it off and check for debris in the impeller. Clean with gloves and ensure your pump is properly placed and powered. Persistent issues could mean it’s time for a replacement.

6. Electrical Issues in the Plant Room

Pool equipment typically runs on a 20-amp circuit. Incorrect voltage or improper setup can cause fires or electrocution risks.

Stay Safe: Ensure there’s a disconnect switch installed away from the water’s edge. For any electrical modifications or concerns, always consult a certified electrician.

7. Faulty or Worn-Out Filters

Finding sand in your pool? That likely points to cracked laterals inside your sand filter. While sand filters are reliable, they do need occasional attention.

Upgrade Idea: Replace the sand every 5 years, or consider switching to AFM (Activated Filter Media), a premium glass-based option that’s more efficient and bio-resistant.

8. Leaks in the Plant Room

Leaks can be more than a nuisance - they may indicate structural damage or faulty piping.

Next Step: Call in a pool engineer to run a pressure test. In some cases, seasoned pros can spot the issue with a quick inspection and offer fast fixes.
