Understanding the Hayward Salt Cell: How It Works and Why Cleaning Matters

To effectively maintain your saltwater pool, it’s crucial to grasp the inner workings of a salt cell and its role in the chlorination process. This understanding highlights the importance of regular cleaning.

The Salt Cell: Your Chlorine Generator

At its core, a salt cell is an electrolytic device that transforms ordinary salt (sodium chloride) into chlorine.
The science is relatively simple: as saltwater, generated by adding pool-grade salt to your pool water, flows through the salt cell, it passes over a series of electrically charged plates.

This process, known as electrolysis, breaks down the sodium chloride molecules, releasing chlorine gas.
The chlorine then dissolves in the water, sanitizing the pool and eliminating bacteria and algae. Afterwards, the chlorine reverts back into salt, and the process starts again.

Hayward’s Role in Salt Chlorination

Hayward is a leading manufacturer of salt chlorination systems, renowned for their reliability and user-friendly design.
Their salt cells are designed to efficiently convert salt into chlorine, maintaining consistent sanitation levels with minimal user intervention.

Hayward salt systems offer several advantages. They automate chlorine production, reducing the need for manual addition of chlorine tablets or liquid chlorine. They provide consistent and reliable sanitation, preventing algae blooms and maintaining water clarity. Many Hayward systems have automated or manual cleaning features to manage calcium buildup.

However, even with these features, understanding potential problems and performing regular maintenance is essential to optimize the system’s performance and extend its lifespan.

The Problem of Calcium Buildup

One of the most common issues affecting salt cells is calcium buildup, also known as scaling.
This occurs because calcium and other minerals naturally present in pool water tend to precipitate out of solution and deposit on the cell’s plates, especially in areas with high pH or water hardness.

Why Does Calcium Buildup Occur?

Several factors contribute to calcium buildup:

• High Calcium Hardness: Water with elevated calcium levels is more prone to scaling.

• High pH: A pH above the recommended range of 7.2-7.8 encourages calcium precipitation.

• High Alkalinity: Similar to pH, high alkalinity promotes scale formation.

• Water Temperature: Warmer water can accelerate the rate of mineral deposition.

The Effects of Calcium Buildup

Calcium buildup has several negative consequences:

• Reduced Chlorine Production: The scale acts as an insulator, hindering the electrolytic process and reducing chlorine output.

• Increased Energy Consumption: The salt cell must work harder to produce chlorine, consuming more energy and increasing electricity bills.

• Shortened Cell Lifespan: Excessive buildup can damage the cell’s plates, ultimately shortening its lifespan and requiring costly replacement.

• Error Codes: Many salt chlorinators are intelligent enough to trigger an alert, often related to low flow or low salt levels due to the buildup inhibiting chlorine generation.

Regular cleaning to remove these deposits is critical to keep your Hayward salt cell working efficiently and extending its life.

Preparation: Setting the Stage for a Safe and Effective Clean

Just as a chef meticulously prepares their mise en place before cooking, preparing the necessary materials and understanding safety protocols is paramount before embarking on cleaning your Hayward salt cell. Rushing into the process without proper precautions can lead to ineffective cleaning, damage to your equipment, or, more importantly, personal injury.

Always lubricate O-rings with a silicone-based lubricant before reinstallation. This ensures a proper seal and prevents the O-rings from drying out and cracking. Petroleum-based lubricants can damage the rubber, so stick with silicone.

By prioritizing safety, gathering the necessary supplies, and paying attention to the condition of your O-rings, you’ll be well-prepared to clean your Hayward salt cell effectively and safely.

The foundation is laid, the supplies are gathered, and safety measures are firmly in place. Now, it’s time to tackle the calcium buildup hindering your Hayward salt cell’s performance. We’ll cover two distinct cleaning methods, starting with the gentler vinegar soak for tackling mild deposits and progressing to the more aggressive muriatic acid approach reserved for stubborn cases. Remember, patience and meticulous execution are key to achieving optimal results.

Cleaning Methods: A Step-by-Step Guide to Removing Calcium Buildup

The approach you take to cleaning your Hayward salt cell depends on the severity of the calcium buildup. For minor deposits, a simple vinegar soak often suffices. However, when confronted with substantial scaling, muriatic acid becomes necessary. Regardless of the method chosen, always prioritize safety and ensure proper ventilation.

The Vinegar Soak Method: Gentle Yet Effective

Vinegar, readily available and relatively safe, is an excellent first line of defense against calcium buildup. This method requires patience, as the acetic acid in vinegar gradually dissolves the mineral deposits.

Step 1: Removing the Salt Cell from the System

Before any cleaning can commence, you must isolate the salt cell.

First, power off the pool pump entirely. This prevents water flow and eliminates the risk of electrical shock.

Next, carefully disconnect the salt cell from the plumbing system. Typically, this involves loosening unions or fittings on either side of the cell. Be prepared for a small amount of water to spill during disconnection.

Step 2: Soaking the Salt Cell in Vinegar

Once removed, inspect the salt cell for the extent of calcium buildup. Fill a bucket large enough to completely submerge the cell with white vinegar. Ensure the vinegar covers all the plates within the cell.

Allow the salt cell to soak for a minimum of 4 hours, and ideally overnight (8-12 hours). The soaking time depends on the severity of the buildup.

Check the cell periodically. You may observe bubbling as the vinegar reacts with the calcium.

Step 3: Rinsing Thoroughly

After the soaking period, remove the salt cell from the vinegar. Using a garden hose with a spray nozzle, thoroughly rinse the cell’s interior. Direct the water stream to dislodge any remaining calcium deposits.

Inspect the plates closely to ensure all visible buildup has been removed. If necessary, repeat the soaking and rinsing process.

The Muriatic Acid Cleaning Method: For Heavy Buildup

Muriatic acid is a powerful chemical and should only be used when vinegar proves ineffective. Extreme caution is essential when handling this substance.

Step 1: Diluting Muriatic Acid Safely

Always add acid to water, never the other way around. This prevents a potentially violent reaction.

In a well-ventilated area, pour a measured amount of water into a plastic bucket. Carefully add the muriatic acid to the water, aiming for a ratio of 1 part muriatic acid to 10 parts water.

Wear appropriate safety gear: chemical-resistant gloves, eye protection, and a respirator if ventilation is limited.

Step 2: Soaking the Salt Cell Briefly

Submerge the salt cell in the diluted muriatic acid solution. Monitor the cell closely. The acid will react quickly with the calcium.

Do not soak the cell for longer than 15-20 minutes. Prolonged exposure to muriatic acid can damage the cell’s plates.

Step 3: Neutralizing the Acid

Carefully remove the salt cell from the acid solution. Prepare a solution of baking soda and water (approximately 1 cup of baking soda per gallon of water).

Submerge the salt cell in the baking soda solution to neutralize any remaining acid. This step is crucial to prevent corrosion.

Step 4: Rinsing Thoroughly

After neutralization, rinse the salt cell thoroughly with a garden hose until all traces of acid are gone. Ensure the rinse water runs clear.

Visually inspect the cell to confirm that all calcium deposits and any remaining acid residue have been removed.

Warning: Handle Muriatic Acid with Extreme Care

Muriatic acid is corrosive and can cause severe burns. Always wear appropriate safety gear and work in a well-ventilated area. In case of skin or eye contact, rinse immediately with plenty of water and seek medical attention. Proper disposal of muriatic acid is crucial — consult local regulations for guidance.

The cleaning is complete, the calcium vanquished. Now, it’s time to return the revitalized salt cell to its rightful place within your pool system, ensuring it operates efficiently and prolongs its lifespan. Proper reinstallation and ongoing maintenance are just as crucial as the cleaning process itself.

Silicone lubricant helps the O-rings slide into place easily, creating a secure and watertight seal. This step is vital to prevent leaks and maintain optimal system pressure.

Step 2: Proper Re-installation of the Salt Cell

With the O-rings inspected and lubricated, it’s time to carefully reinstall the salt cell into the plumbing system.

Ensure the power to the pool pump remains OFF throughout this process.

Align the salt cell with the plumbing connections and gently push it into place. Tighten the unions or fittings by hand until snug. Avoid over-tightening, as this can damage the O-rings or the salt cell itself.

Once the connections are secure, double-check for any leaks before turning the pump back on. If you notice any water dripping from the connections, tighten the fittings slightly until the leak stops.

Turn the power to the pool pump back ON.

Monitor the system closely for any signs of leaks or unusual noises. If everything appears to be functioning correctly, you can proceed to the next step.

Step 3: Preventative Measures to Minimize Calcium Buildup

The battle against calcium buildup is an ongoing one. However, with proactive measures, you can significantly reduce its occurrence and prolong the life of your salt cell.

Water Chemistry Balancing

Maintaining proper water chemistry is the single most effective way to prevent calcium buildup. Regularly test your pool water and adjust the levels of pH, alkalinity, and calcium hardness as needed.

Ideal ranges typically are:

• pH: 7.2 – 7.8
• Alkalinity: 80 – 120 ppm
• Calcium Hardness: 200 – 400 ppm

Consult your pool’s manufacturer’s guidelines or a pool professional for specific recommendations.

Regular Salt Cell Inspections

Make it a habit to inspect your salt cell regularly, at least once a month. This allows you to catch any early signs of calcium buildup and address them before they become severe.

A visual inspection can be performed quickly and easily. Look for any white, flaky deposits on the cell plates. If you notice any buildup, consider performing a vinegar soak as described earlier in this guide.
