Saltwater Pools and Pool Pumps: What You Need to Know

Swimming pools have long been a source of relaxation, recreation and a way to beat the heat during the scorching summer months. While traditional chlorine pools have been the norm for decades, saltwater pools have recently gained popularity.

This article dives into the world of saltwater pools and explores the essential role that pools or water pumps play in maintaining these modern aquatic oases.

The Rise of Saltwater Pools

For several reasons, saltwater pools have become a sought-after alternative to traditional chlorine pools. They offer a more gentle and natural swimming experience, with water that feels softer on the skin and is less likely to irritate eyes and lungs.

Additionally, saltwater pools are perceived as being more environmentally friendly, as they reduce the need to store and handle harsh chemicals like liquid chlorine.

How Saltwater Pools Work

Saltwater pools operate on a simple and ingenious principle. Instead of directly adding liquid chlorine or chlorine tablets to the water, they use a salt chlorinator system. This system comprises a salt cell or generator, a control panel, and a circulation pump.

Here’s how it works:

  • Salt Cell: The salt cell is installed in the pool’s plumbing system and contains a set of titanium plates coated with a thin layer of precious metals. When pool water passes over these plates, an electrolysis process occurs.
  • Electrolysis: The salt chlorinator system produces a low-voltage electrical current in the salt cell. This current breaks down the salt (sodium chloride) in the water into its basic components: chlorine gas and sodium hydroxide.
  • Chlorine Generation: The generated chlorine gas dissolves into the pool water, effectively sanitizing it. This process continuously generates a supply of chlorine, eliminating the need to add chlorine manually.

The Role of Pool Pumps

  • Circulation: Pool pumps are responsible for moving the water in the pool, which is vital for the uniform distribution of chlorine and other pool chemicals. Proper circulation ensures that the pool water is sanitized effectively.
  • Filtration: Pool pumps push water through the pool’s filtration system, which removes debris, leaves, dirt, and other impurities from the water. Clean water is more pleasant to swim in and extends the life of pool equipment.
  • Salt Cell Efficiency: The salt chlorinator system relies on water circulation to distribute the chlorine generated by the salt cell evenly. A well-functioning pool pump ensures that the water passes through the salt cell consistently, optimizing the chlorine production process.

Choosing the Right Pool Pump

  • Pump Size: Select a pump size that aligns with your pool’s dimensions. An oversized pump can lead to excessive energy consumption, whereas an undersized pump may fail to deliver sufficient circulation and filtration.
  • Pump Speed: Variable-speed pumps are a popular choice for saltwater pools. They let you adjust the pump’s speed based on your pool’s specific needs, saving energy and reducing operational costs.
  • Energy Efficiency: Look for pool pumps that are ENERGY STAR certified. As they are designed to operate efficiently and reduce energy consumption.
  • Durability: Opt for a pump crafted from corrosion-resistant materials since saltwater pools can be corrosive.
  • Maintenance: Consistent upkeep is vital for the smooth operation of your pool pump. Regularly clean the pump’s strainer basket and inspect it for any indications of wear or deterioration.


Saltwater pools have become prevalent for those seeking a gentler, more environmentally friendly swimming experience. These pools rely on salt chlorinator systems and efficient water pumps to maintain water quality and ensure a pleasant swimming environment. Understanding the principles behind saltwater pool operation and the role of pool pumps is essential for keeping your pool in optimal condition.

So whether you’re considering converting your pool to saltwater or already have one. Knowing how these systems work will help you enjoy a clean and refreshing swim all season long.
