What To Consider In The Best Water Softener - Our Complete Buying Guide

Buying a water softener for your home is not an easy task and is a huge investment, so when your pick your model you need to be certain your choosing the right type of softener with the features you need. 

To help you out with the buying process and to give you everything you need to know we've put together an extensive buying guide down below which will cover everything from hard water symptoms in your home to how to install a softener in your home and what you need to be watching out for in the best model. 

How Do I Know If I Have Hard Water? 

Since a water softener model is such a huge investment, you need to be certain that your home needs one before purchasing and installing to avoid wasting money.

Hard water occurs in many UK households due to the water supply having a high mineral count, most minerals are safe to drink in your water to a degree, however high hardness of water from calcium and magnesium can cause undesirable effects in your home. 

If you have a hardness of water then you probably already know about it, symptoms such as limescale build-up and damage to plumbing are a few of the consequences. 

We've listed some of the major symptoms that indicate you have a hard water problem below. 

  • Unclean dishes - If you've cleaned your glassware or dishes only to notice that they are cloudy or spotty then this is due to the hardness minerals in your water supply.
  • Dull clothing - Clothing or bedding which feels crusty or looks dull could be due to the hardness of minerals in the water.
  • Dry skin - If your skin feels irritated and dry after taking a shower then it's likely due to a high level of water hardness, these extra minerals can dry out your skin.
  • Poor water pressure - Overtime, limescale build-up on showerheads and other devices can start to affect the pressure from your taps due to the high mineral content.
  • Limescale everywhere - From white stains on your sinks to your shower glass and sinks, appliances from limescale build will show if your water is hard.
  • Your water might taste off - One of the last symptoms that your water supply could be hard is if you can taste iron, certain bacteria can react with these minerals to give an off-taste.

How Do Water Softeners Work? 

Most water softeners work with an ion-exchange system to replace the minerals in your water supply, this can differ however according to the type of water softener that you buy which we will discuss next. 

For now, let's go over the main parts of an ion-exchange water softener model to see how they work. 

  • The brine tank - A brine tank in your water softener is where your salt is stored, this solution is used to flush the mineral tank in the softener, this is also the part of the water softener model that you will refill with salt when needed.
  • Mineral tank - The mineral tank is the most important part of your water softener since this is where the purification of soft water takes place. In this tank, the hard minerals like magnesium and calcium get removed by becoming attracted to the positively charged resin beads.
  • Control valve - Controlling the flow of water during the regeneration process takes place in the control valve. 
The Best Water Softeners Reviews & Buying Guide - BWT WS555 Hi Flow 4

What's The Regeneration Process?

The regeneration process is what cleans the resin beads in your mineral tank, and in the typical water, the softener will be done every couple of days.

  • Backwash - This is what starts the regeneration process, reversing the flow inside of the tank and taking out any debris.
  • Recharge - The salt solution from the brine tank is now pumped into the mineral tank removing the level of water hardness and flushing out the minerals. 
  • Rinse - Now the mineral tank will refill and rinse and the ion-exchange process takes place. 

Different Types Of Water Softeners

As we mentioned above, most water softeners work with a salt ion-exchange system to filter the water inside, but you can find different softeners on the market which use other processes for filtration. 

We've listed a few below. 

  • No saltwater softener - No salt water softeners use potassium chloride instead of salt which is a good option if you are trying to watch how much salt is in your water, this can also help with descaling.
  • Salt-exchange water softener - These are the types of softeners we discussed above which have resin beads in one tank and saltwater in the other.
  • Magnetic water softener - Magnetic water softeners clip onto your water pipe with a magnetic field to change the minerals.
  • Dual-tank water softener - Dual tank softeners have two tanks for the resin solution, this allows you to continue to use one tank while the other one is regenerating.

Benefits Of Installing a Water Softener

As we mentioned above, a water softener gets rid of all the nasty minerals in your water which are causing hardwater issues such as plumbing problems or soap scum, so to help you figure out whether or not buying one is worth it, we've summarised the benefits of investing in one of these softeners below. 

  • It can save you money - Mineral build up in your water pipes can ruin your appliances and cost you money with plumbing repairs.
  • Less cleaning time - Due to having no hardwater, cleaning time is reduced due to the soap being better dissolved without the after-effects of stains.
  • Softer clothes - Using a water softener for your clothes stops them from becoming too hard due to the little amount of detergent needed.
  • Better skin and hair - No hardness minerals in your water means softer skin and hair, you will also need less shampoo to get a lather.

Are There Any Disadvantages To a Water Softener?

Although water softeners come with a huge range of benefits, there are a few notable disadvantages too, for example, water softeners are often very expensive to install as well as maintain due to the constant need to top the device up with salt. 

The high salt content of the water is also not suitable for people to drink, calcium and magnesium can also be beneficial to consume to some people in their diets.

Important Features To Consider In a Water Softener 

Once you've narrowed down the type of water softener you want, you also need to consider the specs of the softener to see whether or not the softener is right for you. 

We've listed the most essential features to watch out for in your water softener below. 

  • Single or dual tank - In our reviews above, you might have noticed you can get single or dual tank water softeners. Dual tank softeners allow you to make use of one tank while the other one is used during regeneration, meaning you have access to soft water 24/7.
  • Timer - Having an electronic timer on your softener is great for setting the device to refresh without manual interference and can help to monitor your water usage.
  • Size and capacity - Water softeners come in different sizes depending on the model you need, you should consider if you need a compact design or not to put in your cupboard. Softeners also come with varying capacities, most houses need a grain capacity between 10,000 and 20,000.
  • Weight - Consider whether or not you need a portable softener for your home, these devices can become very heavy with some weighing up to 22kg, this isn't an issue if you plan for your softener to stay in one place but could be an issue if you need to move it around.
  • Design - Make sure that your softener is durable and well built, some have fibreglass material to make them even sturdier. Consider whether the design includes an LCD as well for ease of setting. 
  • Installation - Installation of your device should be straightforward, most devices come with either a 15mm or 22mm hose connector and a manual, you should be able to fit your softener without a plumber but it's best to ask for help if you are unsure.
  • Water flow rate - The flow rate of your softener refers to the number of litres per minute your softener can produce, the bigger the number of people and faucets your household has then the higher the flow rate needs to be.
  • Auto regeneration - Automatic regeneration is a handy feature to look for as it gives you peace of mind that your softener with produce soft water without manual interference, auto regeneration essentially means that it regenerates itself at a set time, leaving you only to top up the salt level inside when needed.
  • Warranty - Always make sure that your softener has a one or two year warranty, this will keep you covered if you have any early on issues with your softener.

Can I Drink Softened Water?

If you've decided that a water softener is right for you and narrowed down your top pick, you might not have considered one important issue, can you drink the softened water? 

Well, drinking softened water is down to personal choice, if you decided to drink this water you should be aware that it has higher amounts of sodium due to the ion-exchange process, if your following a low-sodium diet we would suggest avoiding drinking this softened water. 

Our Guide To Installing Your Water Softener

Many people use a plumber to install a water softener, but you can install a softener at home yourself as long as your model comes with a simple installation kit and instructions. 

We've put together a step by step guide for installing your water softener at home below. 

  • Step one - First of all start by locating the manual which came with your manufacturers of water softeners and turn off all the water supply into your house as well as the hot water power. 
  • Step two - Turn on any taps you have outside to completely drain the water supply then position your softener where you would like to be near the cold water supply. Measure how far it is between the cold water supply and the bypass port on the softener and cut a copper pipe then solder it onto both ends.
  • Step three - Now install the discharge tube on the model, run the overflow tube and discharge tube to the drain and put the bypass valve on the softeners head valve, you might need a screwdriver for this.
  • Step four - Then connect the copper water tube to the bypass valve and attach it to the water lines, making sure everything is well connected and tight. 
  • Step five - Turn the water heater back on, plug the control valve and pour around 15 litres of water into your brine tank, set to backwash and the bypass valve to service. Switch the water supply valve on when water appears at the drain. 
  • Step six - Let the backwash cycle complete and check for leaks, if all is well enjoy your softened water!

Is There An Alternative To Water Softeners? 

As we mentioned above in our different types of water softeners, you can find other types of water softeners on the market which work similarly to a saltwater softener but without the salt. 

For example, you have reverse osmosis filters nearly all minerals and bad bacteria's out of your water, potassium chloride softeners that work as a softener without the salt and nucleation assisted crystallisation which prevents up to 90% of limescale build-up.
