Understanding Pool Equipment: A Guide to Pumps, Filters, and More
Whether you’re a new pool owner or simply want to get more out of your backyard investment, understanding your pool equipment is essential. The right gear keeps your pool sparkling, safe, and energy-efficient — but if you don’t know what’s what, it’s easy to overlook small issues that can lead to big problems.
In this guide, we break down the core components of your pool system, what they do, how to maintain them, and tips for keeping everything running smoothly all year round.
- Pool Pump: The Heart of Your Pool System
What it does:
The pool pump circulates water through the filtration and sanitisation system, ensuring your water stays clean and debris-free.
The pool pump circulates water through the filtration and sanitisation system, ensuring your water stays clean and debris-free.
Types:
-
Single-speed pumps (older and less efficient)
-
Variable-speed pumps (more energy-efficient and quieter)
Maintenance tips:
-
Check the pump basket weekly and empty out leaves/debris
-
Listen for unusual noises – screeching or rattling could indicate a motor issue
-
Ensure the pump is primed (not running dry)
Century Tip: Consider upgrading to an energy-efficient variable-speed pump. It can cut energy use by up to 70% and is often eligible for rebates.
2. Pool Filter: The Unsung Hero
What it does:
The filter removes fine particles, dirt, and oils from your water, preventing cloudiness and contamination.
Types of filters:
-
Sand Filters – Easy to use, require backwashing every few weeks
-
Cartridge Filters – Great for water clarity, cleaned manually
-
DE Filters (Diatomaceous Earth) – Super fine filtration, higher maintenance
Maintenance tips:
-
Clean cartridge filters every 4–6 weeks depending on use
-
Backwash sand or DE filters when pressure rises 8–10 PSI above baseline
-
Replace media (cartridge/sand/DE) as needed — usually every 1–5 years
Century Tip: Keep a pressure gauge log. A rise in pressure is the #1 sign your filter needs attention.
3. Chlorinators & Sanitation Systems
What it does:
Automatically dispenses chlorine or salt to sanitise the water and keep it safe to swim in.
Types:
-
Saltwater chlorinators – Gentler on skin and eyes
-
Liquid chlorine dosing systems – Easy, consistent chlorine levels
-
Tablet feeders – Simpler, but less precise
Maintenance tips:
-
Clean the salt cell every 8–12 weeks to avoid calcium build-up
-
Check chlorine levels weekly, even with automation
-
Never mix different types of sanitiser
Century Tip: Automating your sanitising system helps avoid “chlorine peaks and troughs” — essential for swimmer comfort and algae control.
4. Pool Heater (So Valuable)
What it does:
Keeps water warm so you can swim comfortably outside of peak summer.

Types:
-
Electric Heat Pumps – Energy-efficient, great for long-term use
-
Gas Heaters – Fast heating, ideal for short bursts
-
Solar Heating – Cost-effective, weather-dependent
Maintenance tips:
-
Remove leaves and debris from heat pump vents
-
Get your system serviced annually before winter
-
Use a pool cover to retain heat overnight
Century Tip: Combining a heat pump + solar blanket is the most efficient way to extend your swim season.
5. Robotic Pool Cleaners
What it does:
Cleans your pool floor, walls, and waterline automatically — saving you time and energy.
