A report by Thames Water suggests that more than 60% of people live in hard water areas in the UK. A water softener will not ‘cleanse’ or ‘decontaminate’ water or manage the problems with taste or smells associated with natural organic sources.
The pros and cons are manyfold and you will need to do your research first before deciding.

If you have decided and you want to install a water softener serviceteam can install a variety of water softeners of your choice. Just call us for more information and we will provide an estimate for the installation.

Why install a water softener?

Well, the obvious one, it softens down the water but what does that mean? The following points highlight some of the benefits:

Less soap, detergent, shampoo used with more lather/suds.
Reduced scale and residue build-up ensure your plumbing and appliances remain free of clogging or blockages.
Less detergent so a plus for environmentalists.
Your laundry looks cleaner with soft water as opposed to hard, which can cause discoloration.
The water will taste great (it will taste different if you have been drinking the hard water for most of your life and vice versa).

How does a water softener work?

It works by sucking up the magnesium and calcium present in the water supply.
It works on the principle of ion exchange, which removes certain contaminants from your water supply. The process turns hardened water to softened water. Water supplies contain hard minerals and by removing them makes your piping system less susceptible to limescale buildup.

A water softener works on the principle of Ions exchange. Once the water passes through the filter, all the calcium and magnesium ions found inside the water are replaced by sodium ions. For softer water, if you live in a hard water area, the installation of a water softener could be an option to consider, although hardened water does contain essential minerals. Softer water is kinder on the plumbing system and your appliances.

What size water softener do I need?

Well, it depends on the size of your property or business premises and the facilities present.
Some water softeners of a certain size will operate in a property that has up to three bathrooms.
A property with three or more bathrooms the size and capability of the softener will increase accordingly, as it would for a larger detached property or commercial premises.
So, size does matter based on your property size and the amount of water used per head.

Here’s a step by step method to determine the size of water softener suitable for your household:

Multiply the number of family members to the water they consume/use on a daily basis. Yes, it can be difficult, but on average the usage is approximately 70 gallons or 264.97 Ltr to 80 gallons 302.83 Ltr per head.
Now multiply the number of grains in the water with the obtained number. It will give you a rough estimate of how many grains to be removed daily. All a bit too much? Then put the calculator away because there is a simpler way to determine the water hardness with water hardness test strips. Dip the strip into (unfiltered) water for about 20 seconds, then remove it, observe the gradual color change (you can purchase a water test kit online). The next step is to compare it to the color chart to determine your water supplies’ hardness.
You can then start sourcing the water softener that suits your needs..

You can also get expert advice from the water softener manufacturer of your service provider/installer.

Where can a water softener be installed?

Depending on the size of the water softener and in a typical family size home it can be installed in the cupboard under the sink, if enough space is available. It could also be installed in the basement/cellar or garage.

Softened water is perfectly safe for drinking

Soft water does feel softer, it has a sort of silky, slimy feel when handled but gives cleaner glass and cutlery when washed by hand or in a dishwasher. It been said that soft water is good for dry skin conditions and makes hair feel softer.
Reports also suggest that soft water is not good for watering the garden, due to high amounts of sodium drawn from salt. Plants and flowers aren’t too keen on it either. So, don’t use soft water for the garden too often!

Frequently Asked Questions

Q: Can I drink the softened water?

It is safe to drink the softened water however it is not recommended to drink the softened water – for a couple of reasons

It doesn’t taste that nice
It adds sodium to the water (after removing the calcium and magnesium) and the recommended amount of sodium in the water supply will far exceed this amount once a water softener is installed
But don’t worry – our engineers can install a supply direct from the mains that by passes the softener but utilises a filtered water system for you to drink safety.

Q: We’ve heard about no-salt softeners – would you recommend one?

In our experience we believe these to be more hype than anything but future technologies are becoming present technologies but at the time of writing none are better nor more efficient than a salt water softener.

Q: We have a garden tap – can this be bypassed too?

Of course – just mention this to the engineer and we will be happy to assist you.

Q: What is the on-going cost to run a water softener?

This is a complicated question as it would have to take into consideration the size of the softener installed, the quantity of people living in the property, and whether they use above or below the rough guide of 150 litres of water per day, per person.

Q: Does soft water affect the efficiency of boiler?

Yes it does but only for the better. Over time hard water limescale could build up in the boiler heat exchanger and that will mean that the boiler will have to work harder to heat the water to the required temperature. Having less limescale in your heat exchanger means that your boiler will run more efficiently for longer.
