How to Choose the Right Softener For You

Introduction – Making the Right Choice for Decades of Soft Water

After more than 25 years in the UK industry, I absolutely recognise that choosing the right softener for your home with tremendous care is incredibly important.

Choose Well – Invest Once, Benefit for a Lifetime

If you select very well, choosing a domestic softener should be a decision you need only make once every 20–30 years, and in a few cases, the right softener could even last you much longer.  

The Three Main Types of Water Softeners Explained

 There are three main categories of softeners, and knowing the difference can save you from costly mistakes:

1️⃣ Budget Models (3-8 Years Lifespan) – Cheaper upfront, but often built with plastic valves and no spare parts available. Always heavy on salt and water.  Once it fails, it’s landfill.

2️⃣ Plumber/Builder Grade Models (5-13 Years Lifespan) – Reliable for a while, but often designed to be disposable. Repairs? Not always an option, and often only available from the manufacturer at a premium cost.  Normally heavy on salt and water.

3️⃣ High-Quality Consumer Models (15-30+ Years Lifespan) – A long-term investment. Designed to be serviced, repaired, and to last decades when properly maintained.

✔ Moral of the story? If you buy cheap, unfortunately you’ll probably buy at least twice and spend more than you intend, on capital cost and definitely on running cost!

Marketing Hype vs. Best Advice – Navigating the Noise

The Sales Pitch vs. The Reality – What No One Tells You?

So my advice is to take your time and choose well. 

Get independent advice from someone like Hydroworks; that’s us! 

We are totally and completely independent with a lot of experience.  With over 18,000 customer base, and every make and model of machine in our care, we can give you best advice based on solid foundations. 

If you choose your softener carefully, you can reap the benefits for years and possibly even decades.

And of course there is a ‘but’ coming… BUT, choosing well in our sector is not easy because manufacturers and resellers often don’t tell the full story.  There is a lot of marketing hype designed to sell a product, shift a box, and make profit!  This really frustrates me because it feels as though that's all many industries care about!

✔ What should you do? Ask the right questions. Don’t fall for clever marketing - focus on performance, reliability, running costs, lifespan, and proper support.

The Truth About “Soft Water” – Not All Softness Is the Same

Water isn’t just soft or hard - there’s a huge range in between, and what most companies class as acceptably soft water can often in fact leave cosmetic water marks and soap scum.

Most manufacturers don’t talk about the difference between soft water and completely soft water!  Why? 

Because most machines struggle to measure flow rates below 10 litres per minute. 

Of those that can, some do it better than others.  The result? 

Water that may feel soft, but leaves cosmetic staining on sanitary ware or chalk in the water which can have an effect on dry skin conditions.

 

In the video below, this customer chose their softener very well…

When I went to see the customer below, they told me that they had purchased their softener in 1976, over 40 years earlier, for about £1,000 in today's money, which in those days was close to £9,000 - considerably more than we would pay for a quality softener today.

When the customer asked us in to do a FREE Health check on their softener, it was still giving softened water. However, the customer had noted that the time clock was no longer working consistently, and this prompted his decision to ask us to do a check.

The customer understood that servicing their machine was not going to be possible, and was also aware that softeners of today were a lot more efficient than their 40-year old model, and asked us to therefore change it for them.  They wanted the convenience of lighter-weight block salt and the peace of mind of continued reliability.  We chose the Harvey Minimax M3 water softener, the most advanced non-electric softener on the market at the time. Harvey's now also makes the next-generation Minimax Innova.

Their running costs went from £175 a year to just £53!

 ✔ In my professional opinion, a properly specified water softener should give you completely soft water - ALL of the time.  

This is a factor that I think is even sadly misunderstood by the vast majority of our own sector!

The Best Softener for Your Home – How We Help You Decide

The only way to remove chalk, prevent scaling, and keep your sanitary ware sparkling and shiny, plus help protect your skin from hard water (such as eczema), is via a salt-based water softener.

Anyone who tries to suggest another product, such as a 'salt-free softener' or magnetic or electrolytic conditioner or a device that gives you 'structured water' is not looking after your best interests, and is simply trying to put profit into their pocket.  Please don't fall for anyone giving you this misleading and woefully wrong advice!

Let me share a story with you... 

I used to look after a dealer back in my EcoWater days when I was running the UK dealer network for the biggest manufacturer of softeners in the world.  

This particular company sold not only softeners, but also powerful magnetic scale reducers, which they told customers were better than softeners.  That story stayed like that for years until, one day, they started manufacturing softeners.  

Overnight, their sales message changed, and they then started saying that some treatment could be achieved by magnetic devices, but the real answer was softening.  I found it astonishing that the marketing message took a 180° turnaround when business direction changed.  

I know many in our sector feel that the industry is full of smoke and mirrors, creating deliberate confusion for the customer!
 

❓ Did you know that the salt never goes near the drinking water supply, it is purely used to remove the chalk that has been captured from the water supply, and chuck it down the drain via a brine water solution, after which fresh water is used to flush the bed of resin and make the softened water delicious and safe to drink!

The Power of True Independence – Putting Customers First

When I bought Hydroworks, I quickly realised that the previous owner, Jeremy, had agreements with suppliers that came with sales targets. The closer we got to those targets, the more pressure there was to recommend certain products - and not necessarily the best ones for the customer either!

That didn’t sit right with me, and I felt rubbish being led by someone else for all the wrong reasons!

About six months in, I decided to take a stand. I asked our suppliers to cancel all contracts so that I could be completely independent. Some agreed - but many didn’t. In fact, some manufacturers cut off our access to their products entirely.

By month nine, Hydroworks was truly independent - but it came at a cost. Our overheads went up, and some suppliers treated us like outcasts. But the response from customers? Incredible. They loved that we weren’t tied to any brand and could genuinely recommend what was best for them - even if it sometimes made us more expensive.

Fast forward to today, and those same suppliers who once shut us out are now welcoming us back. Ironically, some of the companies that refused to work with us no longer exist.

Being independent means I choose the right product for the customer - not based on targets, but on my unique and extensive experience. Many water softeners look great on paper, but the reality is that some are designed to sell well, but not perform well. At Hydroworks, we only stock what truly works - no marketing gimmicks, no brand bias, just the right solution for your home!

The Rinse & Repeat Trap – When Cheap Softeners Cost You More

In recent years, the marketing machines behind cheaper Chinese water softeners have been in full force - often appearing in print media like the Daily Mail. Companies like EWT and Water2Buy built their success on selling lower-cost softeners wrapped in well-branded subscription plans for servicing and salt.

At first glance, it all seemed convenient and affordable. But for those who took the plunge, the writing was on the wall long before disaster struck. Over time, servicing became harder to access, spare parts became unavailable, and eventually, both businesses shut down. Customers with “guarantees” found out the hard way that a guarantee is only as good as the company standing behind it.

But here’s the real issue: This isn’t new. We’ve seen this happen in other industries—companies launch with cheap, attractive products, scale fast, and then collapse under the weight of poor quality and bad aftercare. Then, like clockwork, they reappear under a different name, doing the exact same thing all over again.

The phrase “rinse and repeat” comes to mind - except in this case, the only ones getting rinsed are the customers who regrettably trusted them.

The Hydroworks Litmus Test – How We Choose our Products

When it comes to water softeners, not all products are created equal. To ensure we only offer the best to our customers, I developed the Hydroworks Product Suitability Test - a four-step process that every product and supplier must pass before earning my endorsement.

✅ 1. Product Reliability – Built to Last, Not Just to Sell

If a water softener fails, it’s not just an inconvenience - it’s a frustration for the customer and a potential trust issue for us. That’s why reliability is non-negotiable in our selection process.

 What makes a reliable softener?

• Proven longevity - a product should last decades, not just years.

• High-quality internal components - not just a fancy exterior.

• Minimal failure rates - we don’t deal with manufacturers that cut corners.

 

 The Truth About Failure Rates:

Somewhere between 2003 and 2006, a Chinese export agent accidentally emailed an  internal report that revealed that exported softeners to America and Europe had a 14% failure rate in the first year, yet they still deemed this “sustainable” because of high profit margins. At the time, American brands like EcoWater and Kinetico capitalised on this error by announcing their failure rates were under 6%, and Harvey Softeners were discussed within the sector at 11% at the time.

Common water softener failure causes:

• Poor build quality - cheap components that break easily.

• Electronic faults - especially in budget models.

• Resin failure due to chlorine contamination - one of the biggest failure causes worldwide.

• Incompatibility with UK plumbing - yes, even some UK-sold softeners aren’t appropriately designed for UK homes!

Bottom line? If a softener isn’t built for long-term performance, it doesn’t make our list!

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

✅ 2. Product Running Costs – What’s the Real Price Over Time?

This is such a massive consideration, so it was hard not to make this number 1 on the Litmus Test. 

Salt and water usage

Some softeners use over 100L of water & 1.3kg of salt per regeneration, while others use as little as 36L of water & 450g of salt.

• More efficient models = lower running costs over time.

Do you want to spend a lot, or a little each year?

Annual Servicing – The Hidden Cost

This is a minefield!  Manufacturers tend to state that if you don't service the machine in line with the recommended instructions, you will invalidate the warranty.  And, depending on what is happening in the market place, they may say 'no servicing required' in the UK, but insist on annual servicing when selling in another market, such as the USA or France.  Talk about smoke and mirror marketing!

Some manufacturers, particularly those that sell through plumbers and builders merchants, such as BWT, even make it impossible for a customer to go anywhere but to them for servicing, securing their customer base and increasing the cost of the service to the customer.  They go further - they educate their customers into the habit of just paying for their annual service through a 'maintenance care plan’, and then when the softeners get older, they just get the customer to replace the machine within the ongoing maintenance plan!

While some softeners require annual servicing (which can become very costly over the life of the machine), interestingly, others state no servicing is required at all (saving a significant amount of money over the life of the machine).

OUR PHILOSOPHY?  Truthfully, I get it from my mentor, Harvey, who had the best Long-Term Thinking.

When I worked for Harvey Softeners, I heard many complaints from dealers because Harvey stated no annual servicing was required. But I recall his reasoning almost word for word, even all these years later:

💡" If you spend all your time servicing the same 100 customers, in 10 years, your business won’t grow. But if you sell quality machines that don’t need constant servicing, you can focus on helping more people and growing the market. That’s how you build a sustainable business".

I'm sure you can see why I fully subscribe to Harvey's way of thinking!

Length of Life – The Best Investment Lasts Decades

A water softener isn’t something you should have to replace every few years - it’s an investment that should last decades. But not all softeners are built for the long haul.

Typical Lifespans:

• Low-end models – 3 to 8 years (if you’re lucky)

• Mid-range models – 5 to 13 years (better, but still not ideal)

• High-quality softeners – 15 to 30+ years (and some go much longer!)

The longer a softener lasts, the better your return on investment. If you buy cheap, you’ll probably end up replacing it sooner, and in the long run, you’ll spend more.

Our Approach? We only recommend softeners that are built to last, with proven longevity and spare parts available for long-term servicing.

 ✅ 3. THE HOLY GRAIL OF WATER SOFTENERS - Softened Water Consistency & Quality 

⚠️ The Truth About Water Quality - Why Consistency Matters

This is arguably one of my most important Product Suitability Tests, I feel.  

If you have a boiling water tap that doesn’t supply boiling water to 100°C, then you won't get the very best cup of tea.

If you have a water softener that can only soften the water within the range of soft, and therefore still leave chalk in the water, then softened water is not going to be as pleasurable to bathe in, and it's going to leave cosmetic water staining on fixtures and fittings as you'll see in the shower photographs a little bit further down. 

More importantly, if you have dry skin conditions in the family, they are not going to be helped if there is still chalk in the water blocking the pores of the skin.  Hard water is even linked to acne because once again, dissolved chalk blocks the pores of the skin!

Advertising Standards and their requirements on our industry

Water Softeners in the UK have to comply with Advertising Standards and do what they say on the box, and that is that they just need to produce water that is soft, 'soft water', which on the scale of hardness (see the hard water table in the section below), equates to anything that is 120 ppm of hardness (or 7 drops of hardness), or below.

Many softeners, over time, might average 5-7 drops on the scale of softness, particularly where water is stored in the property, or water usage is lower.  

The problem with that statement is that manufacturers are slow to tell customers that most softeners struggle to measure flow rates below 10LPM (litres per minute), and they don’t put this in their sales documents, but the clever ones do put it into their service documents as a get-out clause for those circumstances where a customer complains that they are not getting completely soft water. Customers don't buy water softeners thinking that they won't get completely soft water; they just expect it, understandably. 

Below is one such instance: 

In naturally soft water areas (like where I live in Haywards Heath) that fall into the scale of soft - customers still purchase water softeners, not because of scaling, but because of the cosmetic effects and dry skin conditions commonly found in harder water areas. 

If they purchased a softener that could only average 5-7 drops of softness over time due to 'channelling' or 'trickle flow', then they won't get much benefit from their water softener.  So the best answer is to get something that does between 0 and 3 drops, unfailingly.  

What do I mean?  

Well, most of the water we use in our home is below that 10LPM threshold;  

• a dishwasher and washing machine might fill at about 1.5-3LPM depending on the model
  
  
• an electric shower might flow at about 5-7LPM
  
  
• a loft tank system and often even a unvented hot water tank will top up between 0.3-2.3LPM
    
• The only time where we may get above 10LPM is where a powerful power shower is in use, or we are running a bath. 
  
  So much of the water we use in our home can indeed be below 10LPM.

At lower flow rates, ‘channelling’ within the resin occurs, which means that the chalk fills a channel of the resin bed, and the next hard water that comes behind tends to find the easiest route through the bed, and if that is already full of captured chalk, then the water that comes out the other side through the taps will have chalk in them.  

And this leads us directly into ‘trickle flow’.  That is the next big problem most softeners have.  They have off-the-shelf standard paddle metres that can’t measure low flow, and at very low flow rates the metres simply stop doing their job.  The result is that the softener electronics or gearing will think that the softener still has the capacity to soften the water, but the reality is that the cylinder is full of chalk and the customer is getting hard water.

Below are some shower photos from a customer who’s softener was working perfectly, but look at the hard water staining!  What a story this one was - I must do a case study of it!  They simply had the wrong machine for their home.  Sadly, they thought all water softeners were therefore not very effective, and were planning to go back to hard water when their machine eventually broke down.  Luckily we were able to help them out, and give them completely soft water with the right machine for their home.

I often feel many in our industry don't have a deep understanding of the sheer importance of water quality, and the impact of channelling and trickle flow.

• So the consistency of softened water is the holy grail of our sector, in my view!

✅ 4. Manufacturer Backup 

Getting good back-up from manufacturers when it's needed in our sector can sometimes feel like pulling teeth - difficult and painful. 

This is a tremendous shame because sometimes a product is good, but when it goes wrong, and support is needed, if the customer can't get the support they need, they understandably lose faith and have every right to become annoyed. 

And so, we only ever recommend products where the manufacturers give excellent support.  Our customers need to know that they are supported if things go wrong.

If a supplier becomes tardy and doesn’t give good customer support, then that will inevitably impact our willingness to recommend their products, even if the product is great!  There is no value in having a fantastic product you can’t get good support for when you need it.

Some Questions to Think About

Why is it important to get the specification of the softener absolutely correct?

In my opinion, the softer we get the water, consistently, not sporadically, then the better the customer satisfaction, the more their home will sparkle, the happier their skin will feel and the more delighted the family in the home will be.

A well-chosen salt-based water softener should, in my opinion, give you incredibly soft water so that when you shower or bathe, those moments literally become 'WOW' moments. 

You should be able to also walk into your sparkling kitchen and bathroom without all the extra effort of scrubbing and harsh chemicals to remove cosmetic water staining, so common to cheaper or incorrectly specified water softeners.

I believe that every time you use your water, you should be able to remember you have a water softener fitted because the experience is so wonderful.

Additionally, it is very important to ensure that the softener is capable of meeting the needs of the property and the people who live there.

If your property is over three floors with a bathroom on the top floor, careful consideration must be given to the water pressure and flow rates required at the top-level bathroom. Properties designed like this sometimes require a more powerful, larger water softener compared to a standard two-storey home.  But also, increasingly, a few of the better machines can cope with this unique installation well.

The same would apply if you are a larger family – a standard domestic softener in such a circumstance could be expensive to run and inefficient. It would also work so hard that it would last several years less as it would just wear itself out.  No KitKat break moments!

So in these circumstances, it would again be prudent to choose the softener well, sizing the softener carefully to meet the demands of your growing family.‍

However, contrary to the belief of so many people in my industry, when sizing a water softener, it's not always good practice to base it on the type of property, as you would do a boiler, but instead, we base it more accurately on the number of people on average in the home.  There are, of course, exceptions to this rule.

My team at Hydroworks offer a free home survey and completely independent comprehensive advice before you take the plunge and invest in softened water.

✅ How efficient do you want your softener, and how soft do you want your water?

Timer Controlled

Old fashioned, cheaper and less efficient.

Some softeners cleanse themselves at the same time of day, every day, even if they don't need to.

These TIMER softeners are very wasteful of both salt and water. Because they cleanse themselves every day, they work exceptionally hard, require more maintenance, and have a much shorter life span.

Even if a single-cylinder softener is metered, they still typically have an inbuilt manufacturer pre-set timer to regenerate every 3-4 days, regardless.  This is done to refresh the resin bed of chalk and remove any possible bacterial buildup.  This is because this type of softener often will struggle to consistently measure flow rates below 10 litres per minute.
 

Turbine Meter

Old fashioned single-cylinder and Kinetico twin-cylinder.

Most metered water softeners have this traditional aeroplane propellor meter style, but these are prone to letting hard water slip through. This is commonly known as 'slippage', which results in 'Trickle-Flow', which results in hardness remaining in the water, leaving cosmetic water staining.

In our industry, we openly recognise the inaccuracy of these systems, and it's considered best practice to fit extra solutions in the home, where possible, particularly if installed on loft tank gravity-fed systems, or to increase the frequency of regeneration by either changing the time-clock setting or increasing the hardness setting.

Displacement Elster Meter

Most advanced, totally accurate and even used by the water board.

The better the softener, the better the meter.

Within the UK market, the British manufacturer, Harvey, has designed their softener to accommodate the same water meter that is used in your water board-supplied water meters - these are known as displacement water meters, sometimes referred to as Kent Meters.

As we know, if you have a water leak, the water board will bill you for every drop of water you use.  Their powerful metres are just incredibly accurate.  And so, the same can be said for the Harvey Minimax Water Softeners. Their softeners will measure every drop of water used in your home, regardless of the type of plumbing or water system in your home.

They measure even down to a very slow dripping tap, which helps the softener give incredibly soft water.  As a consequence of this, Harveys is the only manufacturer in the domestic sector that guarantees completely soft water at all times, to a maximum of 1 drop of hardness. 

Every other manufacturer states that as long as customer water quality is within a scale of softness of 7 drops or less (see graph below), then the softener is considered to be working within operational parameters. 

Most traditional softeners are operational at 5-8 drops, with some exceptions, which is enough to leave cosmetic water staining due to remaining chalk and hardness in the mains water supply.
