"I had a whole house water softener installed and I am extremely happy with the entire experience. Scott gave me a great price, half of what Culligan charged me. The installers, Brian and Thomas did an outstanding job with the install. They hid the pipes neatly and were very careful and respectful of my home. They explained everything in detail and answered all our questions. This is a great company to work with!"

"Gus at Pro Bright went above and beyond on a Sunday to detect and repair our master bedroom ceiling leak. With water to the house turned off at the street we were desperate to find a contractor who could respond right away. Other contractors offered appointments Monday or Tuesday. Gus responded that he could be here in 2 hours to repair the leaking pipe, but could have Jeff, his water mitigation project manager here within 30 minutes to assess the water damage. These guys were both so professional. They shared the process, timeline and costs, and were prepared to start right away. They promptly moved my disabled husband and his adjustable bed to another room away from the work area assuring his comfort and safety. Gus repaired the overhead leak and turned the water back on. Jeff scheduled the water mitigation process to begin first thing Monday morning. We are especially grateful for the kindness these 2 professionals showed us in our time of need."

"The technician for Carini was very polite and professional. He performed the services and explained the issues we were having with the clogged drains. He also inspected the units outside and recommended seasonal tune ups for the systems.

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"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."

"Scott Fanatizzo was our plumber. First he turned off the water going to all the toilets. Then went outside to check the pressure valve to the house. It was not working and the pressure coming through the house was the same (121) as from the city to the house. After installing a new pressure valve outside, he checked all the toilets inside and found that only one needed the inners replaced. Problem solved. Scott was polite, neat and efficient! He called and left a voice message alerting me that he would be early, plus I received an email from the company telling the name of the plumber that would be doing the work along with his picture. Awesome customer service!! Great company!!"

"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!"

"The gentleman who came was very friendly and  quick to do what he came for.  He explained some things that will help us perhaps in the future and noted that our plumbing was all running well and  looked good!  I would recommend this company and this technician!

Water Softeners FAQs, answered by experts

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use tools like Angi’s state licensing tool to verify an installer's license status.

Hard water is not considered unhealthy and is safe to drink, cook with, and bathe in. It doesn't pose a risk to your physical health and can even help you get enough essential minerals like calcium in your diet. However, it can negatively affect skin and hair. Using hard water for washing can contribute to dry skin, an itchy scalp, and may worsen conditions like eczema by altering the pH balance. Additionally, some people do not like the taste of hard water.

It’s unlikely that hard water on its own could cause substantial hair loss or damage, though it’s true that bathing in hard water can cause your scalp to feel itchy or flaky and might dull your hair’s natural shine. Using high-quality shampoo and conditioner or buying a whole-home water softener can decrease these issues.

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.

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.
