Why You Should Consider a Whole House Water Softener System

What is a Water Softener?

Water is termed "hard" when it contains high levels of calcium and magnesium. A water softener is a device designed to reduce water hardness by removing these minerals. The process involves ion exchange, where calcium and magnesium ions are replaced with sodium or potassium ions, resulting in softened water.

How Does a Water Softener Work?

1. Ion Exchange Process: The incoming hard water passes through a tank filled with ion exchange resin. The resin captures calcium and magnesium ions, replacing them with sodium or potassium ions.
2. Regeneration Cycle: Periodically, the resin needs to be cleaned or regenerated. This is done by flushing the resin with a saltwater solution, which swaps the trapped calcium and magnesium ions with sodium or potassium ions. The waste, including the brine and minerals, is then flushed down the drain.

Benefits of Using a Water Softener

1. Preventing Scale Build-Up

Hard water can lead to scale formation inside pipes, water heaters, and appliances. Scale reduces heat conductivity and water flow, potentially causing clogs and expensive repairs. According to the Water Quality Association, scale build-up can reduce the efficiency of water heaters by up to 48% (source).

2. Enhancing Soap Efficiency

Hard water reacts with soap to form scum, reducing its effectiveness. This impacts cleaning tasks such as washing clothes, bathing, and cleaning dishes. Softened water allows soap to lather better, improving overall cleaning efficiency.

Maintaining Your Water Softener

Water softeners require minimal maintenance, primarily involving the periodic addition of salt. However, certain steps can prolong the life of your system:

1. Use High-Quality Salt: Avoid using standard rock salt, as it can lead to sediment build-up in the brine tank. Opt for evaporated salt, which contains fewer impurities.
2. Annual Cleaning: Clean the brine tank annually to remove any sediment. Even pure salt can contain contaminants that accumulate over time.
3. Addressing Impurities: Some water supplies contain impurities like iron, dirt, and organic matter that can affect the softener. Products like "Rust Out" and "Softener Mate" can help maintain the resin bed.

Installation Considerations

Water Bylaws and Regulations

In the UK, water bylaws require that at least one tap in the house remains unsoftened. This is typically achieved by installing a dedicated tap at the kitchen sink for drinking and cooking purposes. Additionally, outside taps should be fed with unsoftened water to avoid waste.

Ideal Installation Locations

When planning to install a water softener, consider the following:

1. Space Requirements: Ensure there is enough space for the softener unit, typically in the garage, laundry room, or airing cupboard.
2. Plumbing Access: The plumber needs a route from the rising main to the softener site.
3. Waste Disposal: Identify a suitable location for waste water disposal during the regeneration process.
4. Electrical Supply: The softener requires an electrical supply, usually reduced to 12 volts via a transformer.
5. Lead Pipes: If your house has lead pipes, they must be replaced before installing a water softener, as softened water can increase lead pickup.

Electrical Work

All electrical work must be performed by a qualified electrician and conform to current IEE Wiring Regulations and applicable Building Regulations. Check with your local authority’s Building Control Department before starting any work.

Choosing the Best Water Softener Salt

Water softener salt typically falls into three categories:

1. Rock Salt: Mined from underground deposits, it contains higher levels of insoluble matter.
2. Solar Salt: Obtained through seawater evaporation, available in crystal or pellet form.
3. Evaporated Salt: Produced by evaporating moisture from dissolved underground salt deposits, it contains the least insoluble matter.

Recommendations

• Avoid Rock Salt: Due to its high insoluble content, which can lead to sediment build-up.
• Prefer Evaporated Salt: It has the least insoluble matter, making it the best choice for most users.
• Solar Salt: Can be used interchangeably with evaporated salt for light use, but may require more frequent cleaning for heavy use.

Conclusion

A whole house water softener system can provide numerous benefits, from preventing scale build-up to enhancing soap efficiency. Proper maintenance and careful installation can ensure the longevity and effectiveness of your system. By choosing the right type of salt and adhering to local regulations, you can enjoy the advantages of softened water throughout your home.
