How Do I Install a Water Softener

Thinking of investing in a new water softener for your home? Wondering if water softeners are worth it? Are you a little overwhelmed by the process? It’s perfectly natural to want to make the perfect decision for your home’s needs. Thankfully, there is a bit of research you can do beforehand to help you make your decision. The first thing you may want to know is how to properly size a water softener. Here’s the formula if you’re looking to do this on your own.

Figure Out How Much Water is Being Used

This is just about as simple as you would think. The average person uses about 80 gallons of water a day. So multiply that by how many people live in your household, and you’re just about there. Keep in mind those 80 gallons a day is for an average person, so account accordingly for babies who will use barely any water and your rowdy teenager who takes 20-minute showers. Then you should…

Figure Out the Hardness of Your Water 

Once you figure out how many grains of hardness are in your water, you multiply that by how many gallons your household uses and go from there. Water softeners are sold by the amount of grains of hardness, so it is dependent on not just how many people live in your household but your water supply itself. It may seem a little complicated, but a professional water softener company can help with this process.

There are a few more factors that go into it, but knowing how to properly size a water softener is one of the most important things to know when buying a water softener. It really is something you’ll want to keep account of. If you’re ready to get rid of hard water hair, hard water skin and all those hard water stains on your dishes, give Kinetico San Antonio a call today!

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.
