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

Block Salt – Regular and Curve

Block salt for softeners was invented by Harvey Bowden of Harvey Water Softeners back in the 1990s, and its popularity has grown considerably ever since.

Older softeners would have used granular salt, and along later came tablet salt, but these types of salt create a less pure brine solution and means that softeners running on them require more regular servicing. Granular salt can scratch the valve of a water softener too, reducing the life of a softener!

Block salt in its traditional 4 kg rectangular block has become so popular that companies abroad have started to manufacture themselves using often whatever means of salt they can get their hands on.

Over the past 10 years, imported block salt has begun to have an impact on the operation of softeners as the purity of the salt has become increasingly more of a concern.

In 2015, the two leading manufacturers of block salt softeners, Harvey softener and Kinetico both introduced guidance that stated that if block salt that did not meet British standards was used in their softeners, this would invalidate the warranty of the product.

Unfortunately this places the onus on the customer to know what quality of salt they are buying and as a result, Harvey Softener launched a new shape salt called the ‘Curve’, which they could subsequently patent and in the process guarantee salt quality. The use of curve salt does not increase the price of your salt, and still gives plenty of places where it can be purchased from.

Traditional block salt

The Minimax M3 runs on two 4kg blocks of salt and takes the hassle out of refilling your water softener. Unlike the traditional salts that come in heavy 25kg sacks, block salt is packed in convenient 8kg bags which consist of two 4 kg blocks.

Curve block salt

The 5th generation of Harvey’s softeners such as the Minimax Innova run on the new guaranteed premium quality salt, the Curve. It takes four blocks of 2.15 kg curve salt, and these are delivered in recyclable bags of 2 blocks per pack, so that’s just 4.3kg to life, rather than 8kg!! Much lighter, much easier and much better!

‍All Harvey block salt is easy to handle and create a pure brine solution. It is quite common to go to a block salt softener, years after it has been installed, and find the tank clear of debris and build-up.

‍The manufacturer of the Minimax, Harvey Water Softeners, typically state a block of salt per person per month, however, our experience is very different. It is most common for customers in our hard water area to use 3/4 of a 4kg block per person per month. Of the smaller curve, this is typically 3/4 of one smaller pack of block salt per person per month. This equates to a running cost of about £2–£3 per person per month.
