Ireland’s hard water especially in Dublin, Meath, Kildare, and Cork causes limescale buildup that damages boilers, shortens appliance life, and costs households an estimated €250+ per year in excess energy. A water softener from Halpin & Hayward removes dissolved calcium and magnesium, eliminating limescale at the source.
HOW DOES A WATER SOFTENER WORK?
How Does a Water Softener Work?
A water softener uses an ion exchange process to remove calcium and magnesium from your water supply before it enters your home or facility.
The ion exchange process step by step:
Modern units including the Clack systems supplied by Halpin & Hayward use metered control valves that regenerate only when needed, reducing salt and water consumption versus older timer-based models.
We are primarily and industrial water treatment company and as such our equipment is:
Water described as “hard” is high in dissolved minerals, specifically calcium and magnesium. Hard water is not a health risk, but a nuisance because of mineral buildup on fixtures and poor soap and/or detergent performance. As water moves through soil and rock, it dissolves very small amounts of minerals and holds them in solution. Calcium and magnesium dissolved in water are the two most common minerals that make water “hard.”
Best practice is to have your water tested by a laboratory to confirm hardness.
There are a number of ways to confirm whether your water is hard. 1 A simple hardness test can be performed which will determine the level of hardness in water, 2 certain area’s are known for being hard water area’s or 3 neighbors will advise whether the water is hard based on the condition of their tap, kettles or showers.
Halpin & Hayward supplies and installs water softeners for domestic homes, commercial premises, and industrial facilities across Ireland. We are authorised suppliers of Clack valve systems one of the most proven and reliable softener platforms available manufactured to exacting US standards.

For businesses, hard water isn’t just an inconvenience it’s a maintenance and efficiency liability. Halpin & Hayward’s water softening equipment is designed to protect:
Our water treatment consultancy team can assess your full water quality profile and recommend the right combination of filtration, softening, and reverse osmosis to match your operational needs.
Is Soft Water Safe to Drink?
Yes, with a practical note. The ion exchange process adds a small amount of sodium to water typically around 12.5mg per glass, comparable to a single bite of bread. This is not a concern for most people.
For those on medically restricted low-sodium diets, we recommend maintaining a separate hard water tap for drinking water. Our bespoke water treatment systems and reverse osmosis options can provide both soft water throughout the home and a separate purified drinking water supply.
Calcium and magnesium removed by softening are naturally abundant in a balanced diet and widely available through food supplements their removal from water supply is not a dietary concern for healthy adults.
The best type of water softener to get depends on your specific needs, water usage, and the degree of hardness in your water. For most households, a salt-based ion exchange water softener is effective in removing calcium and magnesium ions that cause hard water. If you prefer a salt-free option, consider a template assisted crystallization (TAC) or a reverse osmosis system. It’s important to consider factors such as maintenance requirements, size, efficiency, and cost when choosing the best water softener for your home. Consulting with a professional or getting a water test can help determine the most suitable type of water softener for your situation.
Having a water softener can offer multiple benefits, such as reducing the negative effects of hard water on your plumbing, appliances, and skin. It also helps prevent limescale buildup and improves the effectiveness of soaps and detergents. However, whether it’s better to have a water softener depends on the hardness of your water and your specific needs. Some people may prefer the taste of hard water or want to maintain certain mineral content. Ultimately, weighing the pros and cons based on your circumstances can help determine if having a water softener is better for you.
Water softeners can last for many years if properly maintained. Typically, the lifespan of a water softener can range from 10 to 20 years. Regular maintenance, such as refilling salt and routine cleaning, can help prolong its life. The longevity also depends on the quality of the unit and the volume of water it processes. Regular servicing by a professional can further extend its lifespan.
Most people will know whether their home or factory is in a hard water area because neighbours have a softener or equipment needs protecting against hard water. Hard water is particularly an issue when water is heated causing the calcium and magnesium salts to drop of our solution and cause limescale.
Yes. Your local council keeps records of water hardness in your area. Alternatively call us and we will confirm if you are in a hard water area. We have records of water hardness for most parts of Ireland and can confirm whether you need a softener or not.
A water softener is a vertical vessel that contains an ion exchange media. Water is passed through it allowing the absorption and removal of calcium and magnesium salts from water preventing the deposition of limescale. A softener is required in hard water area’s to protect equipment and fittings and reduces the negative effects of hard water on your plumbing, appliances, and skin.
Hard water can be softened by passing the water through an ion exchange resin where the calcium and magnesium are absorbed. Periodically the hardness needs to be flushed away and the resin regenerated with salt.
The ion exchange media will absorb the calcium and magnesium from the water but it only has a certain capacity. Once that capacity is reached the media is saturated and it needs to regenerate to remove the absorbed calcium so it can work again. This is done automatically by shutting off the outlet, drawing in a brine solution and using a reverse flow (backwash) on the vessel to lift and clean the media. Once backwash is complete the softener will automatically return to service.
This depends on site requirements. A simplex will shut off the water supply during regeneration. This may suit some sites as it can be completed late at night during low demand periods. However if continuous water supply is required then a duplex is necessary.
Usually annual servicing is sufficient. We are available for call out at any time but a correctly maintained and serviced softener should not need more frequent attention.
Yes. We provide simple hardness test kits that will confirm whether your softener is working or not. We recommend that our industrial clients test their softeners at least weekly to confirm good operation.
Maintaining good salt levels in your brine tank is essential. Good water pressure is also a requirement for backwash to ensure the resin bed is lifted and cleaned properly. Power should be constant and drains kept clear.
Domestic softeners take roughly 60 mins and our larger industrial units take up to 90 minutes.
Domestically its not always necessary. Industrially it’s a good idea to have a sediment pre-filter to protect the resin from fouling. Where there are high chlorine residuals in the mains supply a carbon filter may also be considered before the softener as chlorine damages softener resin.
Softeners can act as a reservoir for bacteria as they are often in a warm plantrooms and can be off / stagnant for periods which can facilitate bacteria growth. A good service program will include a regular disinfection of the resin bed.
We recommend pelletised (golf balls!) salt tablets rather than granular because it dissolves slowly and does not congeal at the base of the brine tank causing suction system blockages.
Domestic water softeners in Ireland typically range from €700 to €2,000 depending on capacity, technology, and installation complexity. Commercial and industrial systems vary based on flow rate and site requirements. Contact Halpin & Hayward for a tailored quote.
