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 the position on kidney stones and hard or softened water?

Several studies have been conducted around the above question, but these appear contradictory. The NHS website certainly makes no link between hard water and kidney stones.

We will update this page as more information on this subject is released. However, here follows other sites that may be of interest in your search for the facts.

Over the years, the industry has referred to various studies with one such non-specific reference: What Does Water Treatment and Kidney Stones Have in Common?

The US National Library of Medicine states "As compared with both tap and soft water, hard water was associated with a significant 50% increase of the urinary calcium concentration in the absence of changes of oxalate excretion; the calcium-citrate index revealed a significant threefold increase during ingestion of hard water as compared with respect to soft water (Fiuggi water), making the latter preferable even when compared with tap water. This study suggests that, in the preventive approach to calcium nephrolithiasis, the extra meal intake of soft water is preferable to hard water, since it is associated with a lower risk for recurrence of calcium stones."

There are several websites that discuss the question of hard water and kidney stones, and several state that there is no link, including Does Hard Water Cause Kidney Stones?

Myth or Reality – Are Kidney Stones Caused by Hard Water? states "Very high hardness (above 300 PPM) which is not typical of drinking water originating from surface water and may be associated with a higher risk of kidney stones. In most cases of kidney stones, the blood in a human body, due to certain inherent problems, starts absorbing more calcium from water and food than actually needed. As a result, excess calcium is deposited on the walls of the kidney in the excretion process." Water hardness in Kent, Sussex and London, and many other parts of the UK is typically above 300ppm. A photograph of the calcium in a sediment form can be viewed on Can you drink softened water? … it's easy to connect how the sediment can collect on the walls of the kidneys.

Myth or Reality – Are Kidney Stones Caused by Hard Water? also repeats the above.

Does drinking hard water lead to kidney stones? suggests "The impact of water hardness on urinary stone formation remains unclear, despite a weak correlation between water hardness and urinary calcium, magnesium, and citrate excretion. Several studies have shown no association between water hardness and the incidence of urinary stone formation. A correlation between water hardness and urinary calcium, citrate and magnesium levels has been observed although the significance of this is not known. Some studies suggest that in the preventive approach to calcium nephrolithiasis, intake of soft water is preferable to hard water since it is associated with a lower risk for recurrence of calcium stones. There is, however, no study as yet, which has shown a higher incidence of kidney stones in a population consuming hard water."

Does water prevent stones – what’s your bet? from the University of Chicago suggests that supersaturation causes crystals to form and grow, and states that people who make stones "supersaturate their urine excessively even if the actual measured values are no higher or even lower than those commonly found among normal people. The proof is that they make stones."
