Details
Your Pentair Intellichlor LT25 salt chlorine generator cell works tirelessly to maintain clean and safe pool water. It uses electrolysis to convert dissolved salt into chlorine, which then sanitizes your pool. However, like any component exposed to the harsh pool environment, it has a limited lifespan. Over time, mineral deposits (scale) can build up on the cell plates, reducing its efficiency and ability to produce chlorine. Eventually, the internal components will degrade, and the cell will need to be replaced to ensure proper sanitation.
Ignoring a failing salt cell can have several negative consequences for your pool. Most importantly, your pool will not be adequately sanitized, leading to cloudy water, unpleasant odors, and potentially harmful bacteria and algae blooms. This not only makes your pool uninviting but can also lead to more costly chemical treatments to correct the imbalance. Furthermore, an overworked or failing cell may trigger error codes on your IntelliChlor system, indicating a problem that needs immediate attention to prevent further damage to the system.

Pro Tip
When replacing your Pentair Intellichlor LT25 cell, ensure you clean the electrical connections on both the new cell and the power cord to ensure a solid connection and prevent corrosion. Always follow the manufacturer's instructions for priming the cell before initial startup.
