💦 DID YOU KNOW?
How long should a chlorinator cell last?
Your chlorinator cell works hard behind the scenes to keep your pool water clean and sanitised. But just like any other piece of pool equipment, it won't last forever!
⏳ So, what's the average lifespan?
Most saltwater chlorinator cells last around 3–7 years, depending on the brand, model, usage and how well they're maintained.
Some may last longer, while others wear out sooner.
🔍 What affects the lifespan of your cell?
🔹 Water Chemistry – Poorly balanced pool water can contribute to calcium build-up and premature wear. Keeping your pH, salt levels and calcium hardness within the manufacturer's recommended ranges is important.
🔹 Operating Hours – The more hours your chlorinator operates, the more wear the cell experiences. Running at unnecessarily high chlorine output can also shorten its lifespan.
🔹 Calcium Build-Up – Those white, crusty deposits on your cell plates can interfere with chlorine production. Regular inspection and appropriate cleaning can help maintain performance.
🔹 Maintenance – Keeping your pool water balanced, checking your cell regularly and following the manufacturer's cleaning instructions can make a real difference.
⚠️ A quick tip about cleaning!
If your cell has calcium build-up, always follow the manufacturer's cleaning instructions. Some cells can be cleaned using a properly diluted hydrochloric acid solution, but unnecessary or excessive acid cleaning can damage the cell's protective coating and shorten its life. Never scrape the plates with metal tools!
🔧 How do you know when your cell needs replacing?
Watch for signs such as:
🔹 Reduced chlorine production despite correct water chemistry and settings
🔹 Persistent low chlorine or cell fault warnings
🔹 Visible wear or damage to the cell plates
🔹 A cell that no longer performs properly even after appropriate maintenance
