Why choose a Culligan water softener?​

Discover why having a water softener at home guarantees the advantages of softer water, offering numerous benefits for your household.​

Extend lifespan of your appliances

Culligan water softeners prevent limescale buildup in appliances, like water heaters and dishwashers, increasing their efficiency and longevity. ​

This not only saves you money on repairs and replacements but also reduces energy consumption, contributing to a greener home.​

Reducing the need for harsh descaling chemicals promotes a safer and more eco-friendly household.


Save on household bills

Reduce energy bills by up to 30% with the Culligan Arc water softener. Having a water softener in your home can lead to significant cost savings in several ways:​

Firstly, it prolongs the lifespan of your appliances by preventing limescale buildup, reducing the need for repairs or replacements. This not only saves on maintenance costs but also lowers energy consumption, translating into reduced utility bills. ​

Additionally, the decreased reliance on soap and detergents for cleaning results in fewer purchases and contributes to a more budget-friendly household. Overall, a Culligan water softener proves to be a sound investment that pays off over time, offering both financial and operational advantages in your home.​


Skin and hair benefits

Your skin’s well-being is crucial, impacting your overall health. Scientific research has linked hard water to skin issues, making a water softener a smart investment for healthier skin.​

Softened water is gentler on your skin and hair, preventing dryness and irritation. It can also help in maintaining the vibrancy of your hair colour and reducing the need for moisturisers.​

Softer water can help ease conditions like eczema and reduce the likelihood of developing hard water-related skin issues, promoting healthier, more radiant skin.​


Effortless cleaning

​Soft water minimizes mineral buildup on sinks, showers, and fixtures, making cleaning faster and more straightforward. ​

Surfaces stay sparkling, requiring less effort and fewer cleaning products, which simplifies household chores and keeps your home looking its best.​

This not only saves you time but also reduces the need for expensive cleaning supplies, contributing to your overall cost savings.

Frequently asked questions

View our FAQs for any questions

Is my home suitable for a water softener?

Prior to scheduling an installation, a Culligan expert will conduct a virtual or in-person visit to
demonstrate our services. This includes evaluating your home, discussing potential locations for the
water softener, and addressing any unique installation considerations. They will also identify any
unusual plumbing or water system features to ensure the installation of your water softener can be

What is hard water, and how can I tell if I have it in my home?

Hard water contains high levels of minerals like calcium and magnesium. You can often tell you have
hard water if you notice limescale buildup on taps and appliances, soap scum in your shower, or if
your water doesn’t lather well. Contact us for a free consultation where we will analyse the quality
of your water and test for hardness.

Can I install a water softener myself, or do I need a professional?

While some DIY installations are possible, it’s recommended to have a professional install your water
softener. This ensures it’s done correctly and complies with local plumbing codes. A professional can
also assess your specific needs for the best results. Contact us about our professional installation

How often do I need to maintain my water softener?

Typically, water softeners require maintenance like adding salt to the salt tank and occasional resin
bed cleaning. The frequency depends on your water hardness and usage but is usually every done
annually. Contact us about our maintenance service for water softeners.

Does a water softener affect the taste of my drinking water?

Water softeners primarily remove minerals that cause hardness but don’t significantly impact the
taste of water. However, some people prefer the taste of softened water, while others opt for a
bypass valve to keep one tap with untreated water for drinking.

Do water softeners remove other contaminants like chlorine or bacteria?

Water softeners are designed to remove hardness minerals, not other contaminants like chlorine or
bacteria. For comprehensive water treatment, consider additional filtration or purification systems,
such as Culligan water coolers or instant boiling and chilled taps.
