What to Consider When Buying a Water Softener?

Much of the UK is subject to hard water, meaning the water supply has a high calcium carbonate content. This can lead to limescale to build up in appliances and affect the quality of clothing once it’s been washed, as well as reducing the efficiency of boilers. If you’ve decided to combat the problem by purchasing a water softener system, you may be overwhelmed by the range of options available which can make choosing the right unit for your needs difficult.

There are three categories of water softener solutions, excluding filter systems which use reverse osmosis to purify water, which include:

Salt-based systems

Salt-based water softeners use sodium to replace hard water ions to soften the water. These units need a tank for resin beads as well as a salt chamber or brine tank which should be kept topped up to keep it working effectively. A process known as regeneration refreshes the resin beads which in turn soften the water. These systems are low-maintenance as they’re typically timer or metre-based. The units can be larger and need to be installed near a drain so that the salt tank waste can be drained off.

Salt-free systems

Salt-free units use nano-technology to change the atomic structure of the water in order to soften it, usually in moderately hard water areas. If limescale has already built up in the plumbing system of your home, this form of water softener is highly effective in removing this from the plumbing to make sure the situation doesn’t get any worse. The running costs of salt-free systems are usually lower, and they are easy to maintain, as well as there being no need for them to be installed near a drain. They’re also considered to be eco-friendlier, but they might not be as effective in removing the hardness of the water.

Electro-magnetic systems

Electro-magnetic systems are the smallest units available so they’re ideal for space saving, and they work by using magnetic wires around the water pipes to change the structure of the water molecules to soften the water. This type of system is ideal for low to medium hard water and is also environmentally-friendly. Electro-magnetic systems are easy to install and are low maintenance, as well as being cheap to run.

Water Softeners Features to Consider

Salt – Most water softeners work through the use of salt to remove minerals in the water. Water softener salts usually come in either salt ‘cake’ form or in crystalline form. Some filters will be able to function with any form of salt, while others will specify the type of salt needed, so this should be checked beforehand, so you can choose the most practical option for you depending on the mineral content of the water in your local area.

Capacity – Larger tanks which have larger filters will typically last for a longer period of time without requiring any maintenance than smaller tanks. This impacts how much the unit will cost to run, not just for the device but also the filters it will use.

Efficiency – Efficiency is key to any unit you decide to purchase for the best water softening effects. Some important factors are the size of the reservoir, the quantity of salt it can contain and therefore how long each supply will last before it needs to be topped up, as well as how long the filters will last before they need to be replaced.

Mineral-dense water can cause serious problems to a building’s plumbing and to water-based appliances, as well as causing the body to accumulate potentially harmful amounts of minerals. The following list of water softeners are some of the best on the market to suit a range of needs and water types.

Water Softener Buying Guide

Hard water is a known problem-creator in almost all homes. It causes spots of the glassware and crockery, a film on shower curtains, and build up in pipes and appliances that rely on water. Water softeners can help descale the water and aids in the smooth running of machines.

What Types of Water Softeners Are There?

Several brands sell water softeners. However, you need to know the differences between each and then choose the best one for your home.

  • Salt-free systems
  • Salt-based systems
  • Electromagnet softener or descaler
  • Dual Tank Water softener

How to Select The Best Water Softener For Your Home?

By now you already know the different types of water softeners available in the market. Apart from just understanding how the systems work, you should look at the other considerations.

Water Softener Certification:

Always look for accreditation. Many companies make softeners but are not authorized to do so. Before spending your hard-earned money on softeners, it is still a good practice to check that the brand is certified and has followed all the norms, rules, and regulations governing protocol. Certificates prove that the parts and equipment have passed a safety and quality check. These certificates guarantee that the claims of the manufacturer are valid, and you can trust the word of the brand or company. Manufacturing and safety need to be carefully observed so that you can protect your home and family from harm. Accidents caused due to softeners and other mechanical equipment can prove fatal. Hence, you should always check the certification and credentials of the company before purchasing a softener. If you’re interested in other home items, see our picks on electric showers.

How Much Is A Water Softener?

Different manufacturers may sell a similar product at different rates. Before you finalize on a softener, always check the price from another manufacturer. The quotes that you receive will usually be based on the same norms warranty on the control valve and the resin tank, service structures, regeneration cycles, and the types of control that the equipment offers.

Established companies usually give higher quotes since their softeners have been tried and tested for several years. You should also pay attention to the costs associated with installation. Some softeners can only be installed with the help of a plumber, while some need an engineer from the manufacturer to be present. These charges would be over and above the cost of purchasing the softener. You should also check the monthly maintenance charge before buying.

If you live in an area that has a water recycling system that uses water from sewage plants, it would be a good idea to select an annual maintenance plan with the manufacturer so that you can be assured that the resin and sodium levels to your home are entirely under control.

Restrictions on Water Softeners

It is of no use buying a water softener that is not going to be of any use to you. Before selecting one, you should attempt to get in touch with a representative from the local municipality. Many times, information about water softening measures for citizens is available on government sites. This information usually includes the names of plants and softeners, the sizes and the specifics required to get safe water to homes.

If you are unaware of how to get this information, book an appointment with a local representative, and carry some of the information brochures from different companies. Once you get an idea of the kind of water softener you need, you would be able to look at other aspects like size, type, and requirements.

Some municipalities emphasize on not using water softeners since these rely on salt and resin. If your town has these restrictions, it would be a good idea for you to search for alternatives like salt-free softeners, or softening shower heads for washing, and treating water with aluminum sulfate before spending money and purchasing one outright.

How Does A Water Softener Affect Selling My Home?

If you are planning to sell your house shortly, it is a good idea to consider ways and means to increase the price of the home without making too many changes to it. Houses that have water softeners previously installed always get higher price points than ones that run on hard water, since the pipes, appliances, and household parts are safe from damage and do not need to be replaced every few years.

Installing a water softener helps save time and money in the long term, and if you plan to sell your home in the future, installing a water softener unit before the house goes on the real estate block is an excellent way to get a higher return on your investment.
