A water softener is a device that removes the hardness minerals from your water. It does this by adding salt to the incoming hard water and then removing it after treatment so you can use softened, clean drinking water in your home or business.

Water Softener: Frequently asked questions

What types of Water Softener are there and what determines a good product?

There are two types of water softeners, the salt-based and the resin based. The most common is a salt-based one as it’s cheaper to maintain than a resin based system. However, in some areas where there’s high levels of iron or manganese present in your water supply, you may need to use a resin type instead. This will help remove these contaminants from your drinking water which can be harmful if consumed over time.

A good water softener is one that removes the hardness from your water and leaves it with a low level of salt. The best way to determine if you have a good Water Softener is by having it tested for its efficiency. This can be done at any time, but most people do this when they first install their system or after an extended period of use (usually about 6 months). If you are not sure how efficient your Water Softening System is, contact us today.

Who should use a Water Softener?

Anyone who has hard water. This includes people with well water, city or municipal tap water and even those on a private spring source that is high in minerals such as iron and manganese.

Based on what criteria should you buy a Water Softener?

There are many things to consider when buying a water softener. The first thing you should do is determine what your needs are for the unit and how much space you have available in your home or business. You will also need to decide whether it makes more sense financially to buy a whole house system, which can cost thousands of dollars, or if an under-the-sink model would be better suited for your situation. If you live in an area that has hard water problems then there really isn’t any question about getting one because they save money on soap and other cleaning products over time as well as extending the life of appliances like washing machines and dishwashers by preventing mineral buildup inside them from occurring too quickly.

The first thing you need to look out for is the salt capacity. It should be at least 40% more than your family’s daily water consumption. You also have to check if it has a bypass valve and an automatic regeneration system that will automatically regenerate itself when needed, without any manual intervention from your side.

What are the advantages and disadvantages of a Water Softener?


A water softener is a device that removes the hardness from your water. Hardness in drinking water can cause scale buildup on pipes and fixtures, as well as clogging up appliances such as dishwashers and washing machines. The most common types of hard waters are calcium carbonate (CaCO3) or magnesium bicarbonate (Mg(HCO3)2). Water Softeners use either salt or potassium to remove these minerals from your tapwater by exchanging them for sodium ions within the resin tank inside the unit. This process allows you to enjoy softer skin when showering, less soap scum build-up on bathroom surfaces, fewer limescale deposits around taps and showers etc., reduced wear & tear on household plumbing systems due to scaling/corrosion caused by hard water which will also save money over time.


Water softeners can be expensive to install and maintain. They also use a lot of salt, which is not good for the environment or your wallet. Finally, they are only effective when used with hard water; if you have very soft water then it will do nothing at all.
