Quick Answer

Yes, most salt cells can be rebuilt by replacing the internal titanium plates, gaskets, and hardware. This typically costs $150-300 compared to $400-800 for a new cell. However, rebuilding requires technical skills and is only cost-effective if the cell housing is undamaged and less than 7 years old.

When Rebuilding Makes Sense

Salt cell rebuilding is most worthwhile when you have a premium cell (Hayward TurboCell, Pentair IntelliChlor, or Jandy AquaPure) where the titanium plates have worn out but the housing remains intact. The decision depends on several factors:

• Cell age: Cells under 5 years old are excellent rebuild candidates
• Housing condition: No cracks, corrosion, or thread damage
• Cost comparison: Rebuilds typically cost 50-70% less than new cells
• Warranty considerations: Rebuilt cells void manufacturer warranties
• Technical ability: Requires precision work with small components

What's Involved in Rebuilding

Salt cell rebuilding involves completely disassembling the cell and replacing the core components that generate chlorine. Here's what gets replaced during a professional rebuild:

Titanium Electrode Plates

The heart of any salt cell rebuild is installing new titanium plates coated with ruthenium or iridium oxide. These plates carry the electrical current that converts salt into chlorine. Over time, the coating wears away and plates develop calcium buildup that can't be cleaned off.

Internal Hardware

All internal connections, screws, and electrical contacts get replaced. This includes the bus bars that carry current between plates and any plastic spacers that maintain proper plate spacing. Using original manufacturer specifications is crucial for proper amperage flow.

Gaskets and Seals

New O-rings and gaskets prevent water leaks and ensure proper pressure. The main housing gasket is particularly important as it maintains the watertight seal when reinstalled in your plumbing system.

Professional vs DIY Rebuilding

While some pool owners attempt DIY rebuilds, professional rebuilding services offer significant advantages. Companies like SaltScience, Cell Surgical Repair, and local pool equipment rebuilders have specialized tools and authentic replacement parts.

Professional Rebuild Benefits

• Precision spacing tools ensure optimal chlorine production
• Access to OEM-quality titanium plates and coatings
• Proper torque specifications prevent over-tightening
• 90-day to 1-year warranties on rebuilt cells
• Testing equipment to verify amperage draw

DIY Challenges

• Sourcing quality replacement plates can be difficult
• Improper plate spacing reduces efficiency
• Risk of damaging the housing during disassembly
• No warranty protection if rebuild fails
• Special tools required for some cell types

Cost Analysis: Rebuild vs Replace

The economics of rebuilding depend on your specific cell model and local pricing:

• Hayward TurboCell T-15: New $650-750, Rebuild $200-275
• Pentair IntelliChlor IC40: New $550-650, Rebuild $175-250
• Jandy AquaPure 1400: New $400-500, Rebuild $150-225
• Generic cells: Often not worth rebuilding due to low replacement cost

Factor in shipping costs for mail-in rebuilds, which typically add $25-40 to the total expense. Local rebuilders may offer pickup and delivery services.

When NOT to Rebuild

Several conditions make rebuilding inadvisable or impossible:

• Cracked housing: Cannot maintain proper seal or pressure
• Corroded threads: Won't reconnect securely to plumbing
• Cells over 7-8 years old: Housing materials may be brittle
• Multiple previous rebuilds: Housings wear out from repeated disassembly
• Low-cost cells: Rebuild cost approaches new cell pricing

Maximizing Rebuilt Cell Lifespan

A properly rebuilt cell should last 3-5 years with proper maintenance. Follow these practices to maximize longevity:

• Maintain salt levels between 3000-3200 ppm
• Keep stabilizer (CYA) at 70-80 ppm for salt water pools
• Clean cell every 3 months with 10:1 water-to-muriatic acid solution
• Run system only when necessary - avoid over-chlorination
• Monitor calcium hardness and keep below 300 ppm

Finding Rebuild Services

Search for "salt cell rebuild" plus your area, or contact local pool equipment repair shops. Many offer mail-in services with 5-10 day turnaround times. Always verify they use quality replacement parts and offer warranties on their work.

Before shipping your cell, take photos of any damage and get a firm quote including return shipping. Reputable rebuilders will inspect your cell and contact you before proceeding if additional issues are discovered.
