A year supply 32 ounce ounce multi-treatment that will get your old or not functioning correctly, water softener back into new condition. The water is softened by the internal resin supply. That resin gets fouled and dirty over time, and inhibits the performance. Plumbers will tell you to replace softener or spend $600 to put new resin in. Resin should last 20 years if taken care of. Simply pour the bottle in, regenerate it twice, and you are done. All that garbage will get back washed into the drain and you will get great new performance. Anyone can do this--you need no tools whatsoever, no technical skills--just follow a couple of simple instructions. This was developed by Magnetic Water Technology specifically to avoid costly repairs that people are getting ripped off over. Everything functions better when it is cleaned, and your softener is no exception, whose job is to trap the bad stuff in your water and send it out the drain. So help your softener do it job, and give it a good cleaning. You should give it a shot of a few ounces about every two-three months for peak performance. There is no better product on the market anywhere, as this is manufactured to our grueling standards. Check out our salt-free softeners under magnetic water softeners. Hundreds of thousands sold worldwide to nearly every country. Simple instructions are included, and if you can open a bottle, then you can do this yourself. Beware of watered-down imitations--this bottle is potent, and is powerful enough to clean any water softener that has a brine tank which most do. You may think your softener is just old, and the new ones sure look shiny. But softeners are engineered to work for many years but they do need a little TLC every now and then, so do yourself and your pocketbook a favor, and just fix it--do not replace it. Every salt system need to be internally cleaned at some point. When a softener resin is clean then the unit will function the way it should.
