Read Our COVID-19 Update - 02/11/20

The government have announced a new national lockdown, to start with effect from Thursday 5th November 2020.

The government have also confirmed that trade businesses that work in customer homes may continue as long as they are COVID Secure, which Hydroworks has been throughout the pandemic.

Our team will continue to follow all strict social distancing guidelines, including sanitising and now the wearing of masks in customer homes where customers are present.

If we are working within your home, such as changing a filter or servicing a softener, or installing a new softener, we would ask that the area we are working be well ventilated.

The company policy is that we will sanitise our hands on arrival at your home, and on departure too.  If we touch surfaces within your home, we will inform you which surfaces we have touched, and we will sanitise those surfaces too with a light bleach solution before we leave.

Our salt was manufactured and stored on pallets more than 30 days ago, and will only have been touched by the member of our team who delivers it, and their hands will be sanitised.  We will deliver your salt to your home, and if safe to do so, will leave it in your desired location.  If you would prefer your salt to be left outside your home, then we will ascertain beforehand where your preferred safe point is.

Lastly, we will confirm with you that no one in your home is experiencing symptoms or self isolating when booking the appointment to come and see you, plus when confirming the appointment the day before, Daniel will also confirm that no one in your home is self isolating or experiencing symptoms at that time too.  

As a final precaution, when we are on our way to your home, the individual coming (Laurence, Alex or Pete) will also call you to confirm that not only are we experiencing no symptoms, but to ascertain that no circumstances in your own home has changed either.

We remain committed to the safety of our clients, and together we will get through this safely.

Any questions, please call Laurence on 07976 036101 or email the team on


Drinking water filter systems

For your home and your business

Drinking water filter systems

For your home and your business

Make your drinking water the best it can be


Everyone's perception of flavour is different, and the selling of drinking water bottles, jugs, filters, and purification systems is BIG business.

Many companies love to promote, in my view, underhand tactics that make people worry about their water. These adverts are designed to create fear and doubt, and make people worry about quality of the water they are drinking.


We are very lucky in the United Kingdom.

Although it is relatively accurately reported that every drop of water on the planet has gone through at least six sets of kidneys, the good news is that in the United Kingdom, our mains water is treated to such high standards, and this treatment process is governed by the Drinking Water Inspectorate, under the arm of DEFRA.

So you can be totally reassured - and don't let anyone tell you otherwise -  that the water we get from our mains water kitchen tap is certainly good enough to drink, and so, unlike some other countries, you have the choice to drink it straight from the kitchen tap, if that is what you would prefer to do.

So if the water is good enough to drink, then why do choose to treat it further in our homes at all?​

Most people are really happy in the knowledge that their drinking water supply is clean enough to drink, however, they would like to remove the horrid taste of chlorine and the yuck that is rock chalk from their drinking water that makes their kettles and coffee machines scale-up, and leaves scum on their cups of tea, not to forget the unsightly staining of the mug.

The water that comes out of our kitchen taps has been treated to a point that has been ticked off as meeting all the criteria of drinking water regulations, however from the point where it has been treated and tested, the journey still has a long way to go before the water reaches your home, and is complete.

From time to time in the UK, regional water treatment systems can fail and we are then instructed by the water boards to boil our drinking water.  This happens more frequently in the North West.​

Our drinking water quality needs to be better than the quality that the water boards approved, which is so very far back in the water treatment journey process because that is exactly what it is - very far back in its journey to your kitchen tap.

At the very least it needs filtering to remove the sediment it picks up as it travels through the pipework in roads and to remove the excess chlorine that is used to keep the supply safe from bacteria while it completes its journey to your home.

How many times do we get that pungent smell of chlorine that makes us quickly pull the glass away from our lips, or get the sense of a fishy smell coming from the water?  Or how about when we turn the tap on to find the water all cloudy or fine particles of sediment suspended in the glass or saucepan.

Our kettles scale up.  Our much-loved cups of tea have a film of scum on the top.  We have to use more squash and cordials than is necessary simply to mask the flavour chalk gives to hard water.

In hard water areas of the country, there is a proven link between hard water and people suffering from kidney stones - we know why this is... our bodies can fully absorb dairy calcium, but they can only absorb some rock calcium.  What our kidneys can't filter out gets stuck, calcifying and creating painful kidney stones.

There are many ways to treat our drinking water, each with their own benefits:-

Here are some of them, in order of purity and benefit

1. Straight from the incoming main

Unfiltered water, just as it comes

Mains Tap Water

In most cases, our tap water is perfectly safe, and so, if you want to, you can safely fill a glass of refreshing water straight from the mains water supply, if you prefer.

Many of the homes we visit are, however, either drinking bottled water or using a jug filter, normally because they don't like the taste of the mains tap water they are drinking. This is normally because tap water is heavily chlorinated. The water authorities chlorinate the water supply to kill off bugs, making it safe to drink, but this can leave a pungent smell.

Another reason many people don't drink mains water is it has a really 'cleansed' taste, in other words it tastes of the smell of the purification process often associated with inner cities. One customer recently likened this to going into a public toilets and smelling the cleansed smell of the facilities. That really got me thinking!

2. Jug filtration

This is very much a 1990's way of treating water

Jug filtration

Jug filters were all the rage many years ago, and still remain popular today.  The biggest challenge for them is they are often too big to go in the refrigerator, so end up finding a home on the kitchen counter.  The problem with doing this is that the first thing the filters remove is chlorine, and once we remove chlorine, we encourage bacteria to grow.

The best rule of thumb is that if you do have a jug filter, please protect yourselves and your family by either keeping it in the fridge, or in a cool dark cupboard so that light or warmth cannot encourage the growth of bacteria.

There are many types of jug filter cartridges out there, and they are use one version of coconut carbon or another. Not all coconut carbons are the same though. The cheaper carbon can leave a lingering after-taste that can taste a bit like plastic.

If you are using the real Brita jug filters, these are without a doubt the best we have tested. Brita do three types of cartridges:

Cartridge A - A taste and odour carbon to polish the water,

- Cartridge B - A taste and odour carbon to polish the water, as well as a food grade chemical to help prevent your kettle or coffee machine from scaling, but you'll still get a scum on your tea from the hard water.

- Cartridge C - The top grade cartridge has water softening resin in them which removes the scale from the water, after which the water passes through a taste and odour carbon to polish the water. This water gives the best quality, making a beautiful cup of tea!

Filters can be expensive and many jugs include filter change indicators, reminding us to change them regularly to give the best water quality possible.

3. Multiple or single 10" Filter housings under your sink

Often the traditional, more old fashioned way of treating water

10" filter housings, singular or multiple

These filter housings can either be singular or multiple, depending on the supplier and what sediment or minerals you wish to remove from within the incoming water mains.

If singular, they are frequently just a 10" carbon block filter.  While there are different grades of quality, these filters typically remove chlorine, but some leave a better taste than others.

The housings and pipe fittings can become worn over time, and as they get older, components may require replacement.  They take up a bit more space under the kitchen sink, normally require a company to come in and change the cartridges, and are a little old-fashioned.  We can do so much better now-a-days!

These can be fitted to hard water or softened water.

4. Hard water - inline filtered water

Taste & Odour filtration

Hard filtered water

An alternative to the 10" housing filter is an inline filter, some of which include housing heads or others are more simple like the one above.

There are many on the market, a lot of which are sold online. Our experience of many of these filters available online has not been great - a high proportion of these filters are coconut fines, or coconut sediment with a mesh to capture the debris of the coconut - cheap and ineffective.

The online market is designed to move products quickly and profitably for the companies concerned, so many of the filters online are from Asia, and are being sold by people working from their garages here, in an effort to capture some of the UK market. Many Asian filters leave an aftertaste which can taste like plastic, or work well for 4-6 months but then degrade relatively rapidly thereafter.

The filter we use of this type is one we have worked hard to source. The filter media is a very high grade of premium coconut carbon rather than just coconut fines and lasts typically 12 months or 6,000L, and gives Brita quality water equivalent to Cartridge A in the jug filter section above. This filter can be fitted to the main cold kitchen tap, and in most homes will last the year, and yet not reduce flow rates much at all.

The filter we have had produced will remove taste and odour.  If fitted to hard water, your kettle will still scale up, and you'll still need to use more cordial to mask the chalk in the water, but at least it will be more like drinking bottled water.

5. Hard water - inline filtered water

Scale Reduction, Taste & Odour Filtration

Hard water, filtered with a scale & taste and odour media

Many customers who have hard water at the kitchen sink have begun to move towards an inline water filter that also removes scale.

The filter media is a very high grade of premium coconut carbon rather than just coconut fines and also includes a food grade scale reducer to help protect the kettle and coffee machine from scaling. These need to be fitted to a separate drinking water tap (faucet) on the side of the sink so as not to deplete the scale reducing media too quickly.

The filter lasts typically 12 months or 6,000L, and gives Brita quality water equivalent to Cartridge B in the jug filter section above.

The filter we have had produced will remove taste and odour.  If fitted to hard water, your kettle will still scale up, and you'll still need to use more cordial to mask the chalk in the water, but at least it will be more like drinking bottled water.

6. Soft water - inline filtered water

Softened, filtered water - Taste and Odour filtration

Did you know that it is perfectly safe to drink softened water?  In fact, not only is it safe but the WHO (World Health Organisation) even class softened water as 'wholesome'.  All of that said, the flavour of softened water is very individual.  

To me, (Laurence), I think it tastes like boiled water gone cold - Flat. My mum thinks it has a slight metallic taste. Dad can't tell a difference. Some customers have said it has a sweeter taste, and others think it is exactly as water should taste - clean and fresh!

Fitting an inline filter is a fantastic way of enjoying softened water to its full benefit, and is exceptionally popular with our customers.

7. Reverse Osmosis System

Pure water, everything filtered out

RO systems are really popular with our customers. The quality of water that an RO system gives is beautiful. Using multiple filters, RO systems filter out pretty much everything, including sodium. The main filters are changed annually. Some of these RO systems are unpumped and some are pumped.

Choosing the right one depends on the conditions of the survey, including water pressure. We'll help you choose the right one for your home.

8. Cabinet RO Systems

The Sintra

This specific RO is a premium RO system that offers the latest technology in home water treatment, guarantees the best performance and maximum quality.
