Pentair IntelliChlor Pass-Through Bypass Cell — Winter/Start-Up Dummy Cell, Inline Fit & Leak-Sealed

The Pentair pass-through (dummy) bypass cell for IntelliChlor provides a removable winter or start-up solution that lets you bypass the chlorine generator safely while maintaining plumbing integrity.

This compact pass-through cell from Pentair is designed for pool and spa systems using IntelliChlor chlorination equipment. It replaces the electrolytic cell temporarily when you need to winterize, service, or start up your system without running the salt chlorine generator. Built for compatibility with Pentair control systems and installed inline, it preserves flow and seals while removing electrical connection to the active cell.

How does this bypass cell help during winterization or service?

During cold months or when performing maintenance, you don’t want the active salt cell connected but you still need an intact plumbing path. The pass-through cell installs in place of the working cell so you can continue circulating water, use heaters or chemical feeders, and avoid opening the line.

• Allows circulation without electrolysis
• Maintains tight seals to prevent leaks
• Simplifies seasonal removal and reinstallation
• Fits inline with existing IntelliChlor housings

Will this part work with my existing IntelliChlor system?

The dummy bypass cell is made for compatibility with Pentair IntelliChlor models and control setups. Verify part numbers and housing dimensions against your system, but this component is intended to match the plumbing and electrical bypass requirements of common IntelliChlor configurations.

• Engineered for IntelliChlor integration
• Matches standard mounting and flow orientations
• No electrical connection required when installed
• Simple swap-in for the active cell during downtime

How do I install and remove the pass-through cell?

Installation is straightforward for someone familiar with pool equipment: isolate power, depressurize the line, unthread the active cell, and insert the pass-through piece following manufacturer torque guidelines. Removal reverses that process when you’re ready to reinstall the working electrolytic cell.

• Turn off system power and relieve pressure first
• Use appropriate tools to avoid damaging threads or seals
• Check O-rings and replace if worn during swap
• Follow Pentair torque and alignment recommendations

What should I expect in terms of durability and maintenance?

The bypass cell is a low-maintenance, non-active component built to withstand pool water and typical environmental exposure when installed indoors or in equipment bays. Inspect seals periodically and after each seasonal use to ensure ongoing leak-free performance.

• Robust housing resists corrosion and standard wear
• Minimal upkeep beyond seal inspection and cleaning
• Designed for multiple seasonal swaps over years of use
• Store in a clean, dry place when not in service

Who is this for? Pool and spa owners, service techs, and facility managers using Pentair IntelliChlor systems who need a reliable, plug-and-play solution to bypass the electrolytic cell for winterization, diagnostic work, or temporary shutdowns. If you value preserving plumbing integrity while removing the active chlorine generator, this pass-through cell is a practical, durable option that keeps your system operational without electrolysis.
