Useful Maintenance Tips for Pool Chlorinator Cells

Wed, 23 Nov 2022

What Is a Pool Chlorinator Cell?

A pool chlorinator cell aids in maintaining the cleanliness and safety of a swimming pool's water. This can be achieved by introducing chlorine into the pool water. 

Swimming pools, hot tubs, spas, and other locations with a lot of water frequently use pool chlorinator cells. The cell has two primary components (a cell casing and a cell core) and is typically located close to the pool pump's filter. 

Chlorine granules in the core aid in the water's microbial eradication. Chlorine is contained within the shell so that it cannot vaporize or escape into the atmosphere.


How to Clean Your Pool Chlorinator Cell

One of the most important parts of owning a pool is keeping it clean. This can be done by following a few steps, including cleaning the chlorinator cell.

The first step is to turn off your pool pump and filter, then test the water for chlorine levels. If your levels are too high, you might need to add more chlorine tablets or shock the pool.

The next step is to remove any debris from around the chlorinator cell before removing it from its housing. Remember not to touch any of the electrical components on the inside of the cell because they could cause an electric shock!

Next, remove any dirt or other debris from around where you will be installing your new cell. You might want to use a vacuum cleaner to suck up loose particles.


How long do pool chlorinator cells last?

A pool chlorinator cell is the component of a pool water treatment system that produces chlorine gas. The cell uses an electrolytic process to convert salt (sodium chloride) into chlorine and sodium hydroxide.

Pool chlorinator cells can last for up to 5 years, but it's important to note that this is only an estimate. Factors like the quality of the water, the number of people using the pool, and the frequency of pool use can all play a role in determining cell longevity.


How do I know if my pool chlorinator cell needs replacement?

A pool chlorinator cell is an essential part of a pool’s filtration system. The cell removes, from the water, impurities that would normally be filtered out by the filter media. 

A pool chlorinator cell should last for about two years, but this can vary depending on how often you use your pool and the quality of the water.

A pool chlorinator cell will need to be replaced if you notice any of these signs:

  • The water in your pool is cloudy.
  • Particles are floating in your pool.
  • A strong chlorine smell is coming from your pool or spa.


Maybe it's just a false alarm, but what should you examine to see if your pool's chlorinator cell needs to be replaced?

1. Cleaning time 

Many systems will send a cell inspection notification in accordance with the systems' advised cleaning schedule. This is usually done every 500 hours. 


2. Have you turned on the pool chlorinator cell? 

The cell might be running like normal but not producing any chlorine. Ensure that the auto mode is selected. 

3. Connection 

Recheck the connections at the control box and the cell. Also, inspect the cells’ internal connections (if any).


Maintenance of a Pool Chlorinator Cell

Keep the chemistry in balance at the following points:

  • pH between 7.2 and 7.8
  • Calcium between 200 and 400 ppm

If your pool is properly chemically balanced, only three or four cleanings per year are needed. 


Key Takeaways

Cleaning the cells is easy, but replacing a cell is even simpler. Start by turning off the power to the control box, just as you would when cleaning.  

The old salt cell can be loosened (if necessary) with a wrench. For new cells, you should manually tighten them. It is risky to use tools on plastic components. 

Fortunately, it's rather easy to keep your pool's chlorinator cell operating at peak efficiency and ensure that your pool is always ready for use.
