"AWS was amazing! From the start, the initial consultation was prompt and informative and well detailed. To scheduling our service earlier than expected, they truly work with our urgency for the installation. Our service man Tim was on time and explained the work he was going to complete. Although there were a few hiccups along the way, he made it all work. We are completely excited for our new water softener, reverse osmosis system, and faucet they installed in our brand new home."

"After speaking with Kevin (CEO) about the merits of the One Water System, and my own online followup, I bit, and was scheduled for installation 5 days later. Juan, the installer was on time, courteous, self-effacing, humorous, knowledgable and highly skilled. He replaced the ugly functioning plumbing (piping) with a more contoured professional appearance. After the system instalation, function test, old water softener packed and area cleaned. I was given an outline of positives results to look for.  And, as of 2 weeks after installation, I am very pleased with results. Faucet run faster, wife says hair and skin feels better. Good professional results from beginning to end.

"After two years of failing water quality and despite a $ 2000.00 installation of a whole house filtration system, Rich and his team did a in depth re-evaluation of the water being supplied.  It was found that the chemical in balances neccestitated a system that could overcome the destruction of our pipes, appliances, sanitary facilities.His field supervisot  researched and found the best system for our situation. The entire project was a day's work of removing the failed system, re-plumbing the pipes to fit, plumbing in and out. They are so organized and competent. All their needs are pre-planned for the job. Our water was off just part of the day. The best is that they do not leave any mess for the customer to clean up. While on the job, the rest of the house was checked for any additional plumbing problems. 
Jeremy, the supervisor, is researching for us additional upgrades to our older plumbing. ie., tankless water heaters for an all electric home. 
I have been associated with this company since their founding. Only get better and better."

"I called and setup an appointment for the afternoon.  The dispatcher called back in an hour saying the plumber was free earlier and came immediately.  He was there within an hour and gave me an estimate for the replacement and upgrade that I wanted.  I agreed to the price and within 3 hours I had a new water heater.  I can?t imagine where they could have done any better.

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.

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs
