"The installation technician, Danny, showed up on time and was extremely professional and friendly. He installed a reverse osmosis system under the kitchen sink with a brushed nickel faucet beautifully mounted on our granite counter top, as well as a whole house water filter and softening system in the garage. His workmanship was terrific and the system works great, we couldn't be happier!"

"⭐⭐⭐⭐⭐ Water Heater SOS was a lifesaver! When our water heater broke down, they responded quickly, diagnosed the issue, and had it fixed the same day. The technician was professional, knowledgeable, and took the time to explain everything clearly. Pricing was fair, and the service was top-notch. I highly recommend Water Heater SOS for anyone needing fast, reliable water heater repairs!"

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"Aztec H2O provided a high quality water softener and the install was impressive. Stephen, the owner was very meticulous and took his time to explain the function of the Pentair unit. Best of all, he was a fraction of the cost of other water systems like EcoWater, Culligan, and Life Source! Please call Stephen first!"

Water Softeners FAQs, answered by experts

Choosing involves understanding water hardness levels, household size, desired features, and consulting professionals experienced in suitable system types.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

Hard water stains can be a headache because they will reoccur as long as hard water flows through. Thankfully, hard water stains are not permanent. With the right tools and an appropriate cleaning routine, you can prevent hard water stains from ever building up. However, you might feel like you are stuck in a constant cleaning cycle. In that case, you may consider hiring a contractor to perform routine cleaning.

Hard water doesn’t hurt, but it might feel more abrasive, especially if you have sensitive skin. It’s also about how your skin feels after bathing. You might feel as though you have a sticky film over your body because you do—it’s all that soapy residue left behind because the hard water can’t rinse it off completely.
