Read Our COVID-19 Update – May 2020

As of the 1st May 2021, our team are Lateral Flow testing for the symptoms of COVID twice a week, in order to keep our staff, customers and families safe.

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

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, Paul 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 hello@hydroworks.co.uk

What is reverse osmosis?

Reverse osmosis, often referred to as RO, is the purest form of drinking water. The next level up from RO water is distillation, however, that is not recommended for drinking water.

RO water is where the final finished water that is supplied is totally clean water, without any impurities, and is 100% safe to drink.

From time to time, the question comes up whether by removing minerals from our drinking water we are causing detriment to our health.

It is reported that we get so few minerals from our drinking water that we would have to drink typically 30 L of water per day for those minerals to be effective. We get most of the mineral content from what we eat and supplements, when taken.

One thing I have noted is that a high number of doctors and dentists on our customer base tend to have RO systems installed.

Reverse Osmosis is used both in commercial applications and in domestic applications. Here's how it works in all cases.

What is reverse osmosis remove?

Reverse osmosis removed typically 98% of all impurities, but can be as high as 99.9% in more specialist conditions, such as dentists, medical, window cleaning and laboratories.

The RO system rejects the contaminants we don't want in our water supply by rejecting those to the drain.

In a typical domestic home, here is what RO will remove:

Let's tell you more about the filters and running costs

An RO System is made up of multiple pre-filters (shown as 1, 2 and 3 in the image below) which are needed to filter out sediment and chlorine, which in turn protects the membrane (shown as number 4 below).

The membrane is what does all the work, and it's also the most expensive filter to replace.

So, the best way to protect the membrane is to ensure your RO filter is installed on softened water. A membrane of an RO system installed on hard water will typically last 3 years, whereas a membrane of a RO installed on softened water will last typically 10 years!

Some RO systems have only 3 filters (shown as 1,4 and 5 in the image below), but some have 5 filters. On the cheaper priced RO systems, typically speaking, the more filters, the better the water quality. But be warned, more filters means a higher filter replacement costs each year.

Strangely enough, on premium models, it works the other way around:

  • They typically have a better quality filter, and therefore normally only have three filters
  • LOWER RUNNING COSTS

Worth considering: Read our notes below about remineralising filters!

Here is how a typical domestic RO system works:

Water Purifier System Range

The budget domestic water purifiers

These small low-volume budget RO systems are available in simple 3-stage, 4-stage or 5-stage systems, depending on the preference of the final water quality.

The upside of these budget RO systems is that they are cheaper to purchase. The downside, however, is they are heavier on water usage.

For every 1L of pure water produced, they will typically eject 6 litres of water down the drain in the warmer summer months, but as much as 12 litres of water per 1L pure water produced in the winter months.

3-Stage RO System
A 3-stage reverse osmosis system.

Refreshing water quality, sometimes with a slight perceived aftertaste.

  • These RO systems need 3-6 bar for optimum performance.
  • A higher water waste per litre of purified water is produced.

£250* + VAT = £300 including VAT

4-Stage RO System
A 4-stage reverse osmosis system.

Refreshing water quality, with a more polished composition. The RO can produce up to 7 litres of water per hour.

  • These RO systems need 3-6 bar for optimum performance
  • A higher water waste per litre of purified water is produced

£295* + VAT = £354 including VAT

5-Stage Unpumped RO System
A 5-stage unpumped reverse osmosis system.

Refreshing water quality, with a really smooth polished composition. The RO can produce up to 7 litres of water per hour.

  • These RO systems need 3-6 bar for optimum performance.
  • A higher water waste per litre of purified water is produced.

£318* + VAT = £381.60 including VAT

5-Stage Pumped RO System – Electrical power required
A 5-stage pumped reverse osmosis system.

Refreshing water quality, with a really smooth polished composition. The RO can produce up to 7 litres of water per hour.

  • This budget RO system is ideal for homes with lower water pressure – operates between 0.5–6 bar.
  • A higher water waste per litre of purified water is produced.

£359* + VAT = £430.80 including VAT

High-efficiency domestic water purifiers

3-Stage Compact 75 Water Purifier – Electrical power required
A 3-stage reverse osmosis system.

This is a really compact and yet powerful RO system. The main part of this pumped water purifier can fit underneath a standard kitchen plinth unit, saving you space, and the standard storage tank is small enough to tuck away underneath a kitchen sink.

  • Being high efficiency, it ejects just 1.75 litres of water to produce each litre of pure water. The RO can produce up to 11 litres per hour.
  • The pre-filter needs changing every 6-months, and the post-filter every 12-months. The filters are easy-change

£443* + VAT = £531.60 including VAT

3-Stage Direct Flow Water Purifier – Electrical power required
A premium 3-stage reverse osmosis system, directly fed (no storage tank).

The New Direct Flow 800 RO system is a fine example of RO technology. It utilises a high-pressure pump and the very latest membrane technology to produce Pure Drinking water on demand at a flow of 2 litres per minute.

  • This powerful RO system doesn't need a storage tank although it will produce a faster flow rate of water if one is installed.
  • This is a most efficient RO system and ejects just 1 litre of water to produce a litre of pure water. A HUGE saving!
  • The pre-filter needs changing every 6-months, and the post-filter every 12-months. The filters are easy-change

£750* + VAT = £900 including VAT, plus optionally, the cost of an appropriate storage tank

* Installation is free if installed at the time of a water softener installation, otherwise, typically £120 incl VAT.
