When my old cell wore out, it put extra strain on the chlorinator, which could have damaged the entire system if left unchecked.

Lastly, using the correct replacement cell designed specifically for my Pentair model gave me peace of mind.

My Buying Guides on Pentair Ic40 Replacement Cell
When it comes to maintaining a sparkling clean pool, the Pentair IC40 replacement cell is a crucial component I’ve learned to prioritize. If you’re like me and want to keep your pool’s chlorine generator working efficiently, choosing the right replacement cell is essential. Here’s my guide based on my experience to help you make an informed purchase.
Understanding the Pentair IC40 Replacement Cell
The IC40 replacement cell is designed specifically for the Pentair IntelliChlor IC40 salt chlorine generator. It’s the part that actually produces chlorine by converting salt into chlorine, which sanitizes the pool water. Over time, the cell’s plates get coated with calcium and other minerals, reducing its efficiency. Replacing the cell regularly ensures your pool stays clean and safe.
Signs You Need to Replace Your IC40 Cell
From my experience, here are some indicators that it’s time for a new replacement cell:
- Reduced chlorine production despite normal salt levels
- Error codes on your IntelliChlor system related to cell voltage or performance
- Visible buildup or corrosion on the cell plates
- Pool water feels less clean or has algae growth
Recognizing these signs early helped me avoid bigger pool problems.
Key Features to Look For
When shopping for a replacement cell, I focused on these aspects:
- Compatibility: Make sure the cell is specifically made for the IC40 model to ensure a proper fit and function.
- Durability: Look for cells with strong titanium plates and good anti-scaling coatings for longer life.
- Ease of Installation: Some models are designed for quick, tool-free installation, which saved me time and hassle.
- Warranty: A decent warranty (usually 1-3 years) provides peace of mind in case of defects or early failure.
Where to Buy the Pentair IC40 Replacement Cell
I found the best options through authorized Pentair dealers, major pool supply stores, and reputable online retailers like Amazon. Make sure to check seller ratings and confirm the product’s authenticity to avoid counterfeit parts.
Installation Tips from My Experience
Replacing the IC40 cell is straightforward if you follow these steps:
- Turn off the pool pump and power to the IntelliChlor system.
- Release the cell housing and disconnect the electrical connectors carefully.
- Remove the old cell and install the new one, ensuring it’s seated properly.
- Reconnect all wiring and secure the housing.
- Turn everything back on and check the system for normal operation.
Taking my time during installation helped me prevent leaks and electrical issues.
Maintenance to Extend Cell Life
After installing the new cell, I keep it in good shape by:
- Maintaining proper salt levels (usually 2700-3400 ppm)
- Running the chlorine generator regularly
- Periodically inspecting the cell for scale buildup
- Cleaning the cell with a mild acid solution if recommended by Pentair
Regular upkeep prolongs the replacement cell’s effectiveness and saves money in the long run.
Final Thoughts
Replacing the Pentair IC40 cell is a vital part of pool care that I don’t take lightly. By choosing a genuine, compatible cell and following proper installation and maintenance steps, I’ve kept my pool water crystal clear and safe all season long. Hopefully, my guide helps you make the right decision and enjoy your pool worry-free!
