I previously had a Kinetico Water Softener for over 25 years and the only maintenance recommended in the original Owner's Manual was to add salt.
Nevertheless I asked Martin Water Conditioning to evaluate the status of my unit and it was discovered that it was not performing up to par.
I therefore had Martin Water Conditioning install a modern Kinetico unit.
On the free one month follow-up visit I was pleased to report to the service technician that a water distiller that heretofore had scaled over after maybe a week's worth of use had not required descaling for the entire month, and, what's more, looked as new as the day I purchased it!
So, if you have an older water softener have Martin come out for a free analysis of your current unit's performance. You will be glad you did. And, your appliances will perform better and more economically than you ever could have imagined.
