Salt Water Pool Systems

Salt cells last between 1 and 7 years, but this depends on several factors such as how often the pool is used, water chemistry, and maintenance routines. Proper water balance and regular cleaning can extend the life of the salt cell, while poor maintenance or extreme conditions may shorten it.

You may need to replace your salt cell if you notice that your pool’s chlorine levels are consistently low despite proper salt and water balance. Other signs include error messages on the chlorinator’s control panel or visible damage to the cell plates. If cleaning the cell no longer improves chlorine production, it is likely time for a replacement.

We do not recommend using aftermarket salt cells. While they may seem more affordable, their quality and compatibility are often inconsistent and can cause damage to your chlorinator. Using aftermarket salt cells will also void your manufacturer’s warranty, leaving you unprotected in case of issues. For the best performance and to protect your equipment, always use original manufacturer parts.

Hayward salt cells are designed for durability and last several years, often in the range of 2 to 10 years under normal operating conditions. Lifespan depends on factors such as frequency of use, water chemistry, and how well the cell is maintained.

When a salt cell begins to fail, it produces less chlorine or stops producing chlorine altogether. This leads to poor pool sanitation and can cause the water to become cloudy or develop algae. Ignoring a failing salt cell can result in the need for more chemical treatment or repairs.

A failing salt cell might show visible signs such as mineral scale buildup, corrosion, or damaged plates. Sometimes, the damage is internal and not visible, so performance issues like low chlorine output or frequent error codes are key indicators.

Yes, salt cells should be cleaned periodically to remove calcium and mineral deposits that build up over time. Cleaning helps maintain efficient chlorine production and extends the life of the cell. The frequency depends on your pool’s water hardness and usage, but it is generally recommended once or twice per season.  We recommend using a wooden skewer and water pressure to remove debris whenever possible and only using acid when this method is not enough.

Salt chlorine generators typically reduce or stop chlorine production when water temperatures fall below 10 to 15°C. This is because the electrolysis process that produces chlorine becomes less efficient in cold water. Please consult your specific model's manual for more accurate temperatures.

Many pool owners find salt cells worth the investment because they provide a consistent and automated way to generate chlorine, reducing the need for manual chemical handling. Salt systems often produce softer water and fewer chemical odors, though suitability depends on your pool type, size, and personal preferences.

Salt cells can fail due to factors such as poor water chemistry, like imbalanced pH or calcium hardness, heavy mineral buildup, excessive use, improper cleaning, and natural wear over time. Maintaining balanced water and cleaning the cell regularly helps prevent premature failure.
