After much research Kinetico was an obvious choice

I have been using an older design water softener without problem for the past 24 years. As my softener is installed in my loft carrying 25kg sacks of salt was becoming more of a a problem. after researching the current models on the market I decided on the more compact Kinetico 2020 HE twin cylinder option which uses block salt. This is easier & cleaner to store and handle than the sacks of granular salt. Having narrowed my choice to Kinetico and one other, I found the Kinetico agent "Watercare Softeners Ltd" more knowledgeable and helpful about their product and its installation running cost & salt usage etc. Because the unit is installed in a loft it has been stood inside a plastic 15 gallon cold water tank with a simple overflow to drain. This good idea came from the seller. Installation and start up could not have been simpler. Kinetico installation and customer use literaure is very clear and easy to follow. I recommend this softener and supplier to any prospective customer.
