What a water softener does:

Hard Water Facts

85% of homes in the United States are in hard water areas. Your water is hard if it contains a concentration of hard water minerals, like calcium and magnesium, higher than 17.1 mg/L.

So how does a water softener work?

Water softeners use a process called ion exchange to soften water. Little plastic beads called resin hold ions of sodium or potassium. When a dissolved rock ion is near them, they will drop or exchange the sodium or potassium ion for the dissolved rock ion. When all of the resin in your water softener is saturated with dissolved rock ions, they are “recharged” with a saline rinse. This rinse flushes dissolved rock ions down the drain as the resin grabs sodium or potassium ions again. This process leaves you with clean, soft water.

We're very glad we got this installed. The technician, Alberto, was very polite and thoroughly explained what he was doing and what we would need to do.

Alberto kept me informed on his arrival time. He was professional and exceeded my expectations concerning the install of the water filtration system. I also need to put a plug in for Tracy for her patience and skills at making things happen behind the scenes...a true unsung hero. They both deserve a raise!


I just had my system installed by Alberto and Jay, and I wanted to say that they rocked. Got it all in and gave me some instructions to follow, all while being determined to detail and professional. Thanks, fellas.
