Softer Water Solutions in Phoenix and Scottsdale, AZ
Professional Water Softener Solutions
If you’re tired of stubborn water spots, dry skin, or appliances wearing out too soon, hard water may be to blame. In the Phoenix and Scottsdale areas, hard water is a common issue—but it doesn’t have to be your normal. At Allegiance Water Services, we install and service water softener systems that make your home’s water cleaner, gentler, and easier on everything from your pipes to your skin.
We’re a local, full-service provider offering professional water softener installation, maintenance, and repair—all backed by our commitment to quality, sustainability, and excellent customer care.
What Is a Water Softener?
A water softener is a home system that removes hard minerals—like calcium and magnesium—from your water supply. These minerals are what cause buildup in your plumbing, stains on your sinks, and that “dry” feeling on your skin after showering.
Using ion exchange technology, a hard water softener replaces those minerals with sodium or potassium, giving you soft, high-quality water throughout your home. It’s one of the easiest ways to protect your plumbing and your appliances.
Why Install a Whole Home Water Softener?
If you’re living in Phoenix or Scottsdale, chances are your home has hard water. And over time, that can cost you—literally. A whole-home water softener helps:
- Prevent scale buildup in pipes and water-using appliances
- Extend the lifespan of your dishwasher, washing machine, and water heater
- Improve water quality for drinking, cooking, and bathing
- Help soap and shampoo work better, so you use less
- Reduce stains on faucets, glass, and tile
Many families choose to add a reverse osmosis (RO) system when upgrading their home’s water. RO systems go the extra mile by removing contaminants, improving the taste of drinking water, and giving you that extra peace of mind about the water your family uses every day. Paired with a water softener, it’s a great way to ensure cleaner, safer water for your whole home.

Types of Water Softener Systems
There are several different types of water softeners, and knowing the difference can help you choose the right system for your home. Here’s a breakdown of the most common types:
Salt-Based Ion Exchange Water Softeners
Most common. Most effective.
These systems work by swapping hard minerals (like calcium and magnesium) for sodium or potassium. They’re especially popular in Arizona homes because they’re reliable and long-lasting.
Pros:
- Very effective at softening water
- Great for long-term appliance protection
- Ideal for homes with high hardness levels
Cons:
- Requires salt refills
- May need a drain line for discharge
Salt-Free Water Softeners (Conditioners)
Great for eco-conscious homeowners.
Technically, these systems don’t “soften” water—they condition it by preventing minerals from sticking to surfaces. They don’t remove the hardness, but they reduce scale buildup.
Pros:
- No salt or chemicals required
- Lower maintenance
- Eco-friendly option
Cons:
- Not as effective for very hard water
- Won’t make water feel soft
Dual-Tank Water Softeners
Best for large households or high water usage.
These systems have two resin tanks, so one can regenerate while the other keeps working. That means you always have softened water, even during the recharge cycle.
Pros:
- Continuous soft water, 24/7
- Handles heavy usage well
Cons:
- More expensive
- Requires more space
Water Softener Maintenance Made Simple
To get the most out of your system, a little regular water softener maintenance goes a long way. Here are some quick tips to keep it running smoothly:
- Refill salt when it runs low (usually every 4–6 weeks)
- Clean the brine tank annually
- Use quality salt designed for softeners
- Have it checked annually by a pro
Need help? We offer affordable, reliable water softener service plans so you don’t have to think twice.
When to Call for Water Softener Repair
Even the best systems can run into issues. If your water feels “hard” again or you notice buildup or salt issues, it might be time for water softener repair. Common signs include:
- Mineral spots returning on dishes or shower doors
- Low water pressure
- Salt not dissolving in the tank
- System errors or warning lights
Our technicians will get your system back on track without pushing unnecessary replacements.
Keeping Your System in Top Condition
Ongoing water softener service is key to maximizing the life and performance of your system. We offer:
- Routine inspections
- Filter replacements
- System cleaning
- Performance testing
Whether it’s part of your seasonal home care or a one-time service call, we’re your partner in keeping your system in peak condition year-round.

Would highly recommend. Lawson was very professional.
John was very knowledgeable and pleasant to work with. Unfortunately, he didnt have the parts i needed so he will be returning in a couple of days to do the actual work. I will update after the work is completed.
Highly recommend for Navien install and servicing.
John was extremely professional and courteous explaining in detail the problems with my irrigation system. He made the repairs and added recommendations as well. He was the best! I highly recommend! Pull
John was great. Professional and courteous. Very pleased with his work.
Why should you hire Allegiance? Quality. Dependability. Customer service. Experience. Dedication. Hard work. This company takes quality experience and service to the next level. I haven’t worked with many home service companies who do such a good job like this. From the moment we got the quote, until the minute the job was done, they were reliable and they provided the service we requested. First they came out to inspect the issue. Once they figured out what was wrong, they provided a verbal quote and followed up with a digital quote. I was able to accept the quote digitally and put a deposit down to begin the work. Since our system needed to be replaced, it was quite a process and luckily they had it all under control. They contacted the city and cox communications to flag their underground items so that they knew where to avoid. Then Lawson came out and literally spent an entire day replacing the system. The customer service was above and beyond. Yes there are a million plumbers and irrigation companies out there, but there aren’t as many reputable, trustworthy, licensed and qualified ones like Allegience.
Allegiance Water Services sent a repair man to fix a broken sprinkler head.. He was courteous, pleasant and well informed. He fixed the head and checked to be sure the whole system was working again correctly. I appreciated his service. Thank you
Lawson with Allegiance Water has done work for us the last few times and he’s very polite and professional and has done great work for us!
What a great job by everyone involved in this process!! A new drip system was installed in both the front and back yards - first time a system was installed by real professionals. System works great and is easy to use!! Highly recommend Allegiance!!!
Ruben and Juan were the best! Great attention to details, all zones were color coded, and helped us with the use of the Rain Bird app. We couldn’t be happier with the great work!
Annual service on RO water system. Rommel was friendly, fast and professional.
I have used Allegiance Water since 2018. The company and service is outstanding. John Gonzales was our repair person for this call. He changed our RO water filters, installed a leak detector for the RO, and repaired our water shut off valve. He was GREAT!!! He is very knowledgeable and dependable. I highly recommend Allegiance and their team. Thanks
Excellent job! Will use them again.
Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
Very prompt service and were there at scheduled times. Both tecs that have been here, Dan and John, were outstanding. Very professional staff including Josh. Pricing is reasonable. I would highly recommend this company.
We had a leak in our drip system. Johnny was awesome. He took the time and explained what the problem was and how to get it fixed. He didn't have the part...
Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.
Excellent service. Rommel was very professional. I will call on them again. Marc C.
Allegiance is fantastic. Lawson in particular is a total professional. Super knowledgeable, trustworthy, and efficient. Diagnosed our crazy irrigation issues and came up with a cost effective solution.
Will make sure the job gets done!
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
Lawson installed a reverse osmosis system at our new home today. While he was here, he also helped answer (many!) other questions and helped inspect the home’s irrigation system for me. He was thorough, professional, friendly, and patient. Thanks so much Lawson and Allegiance!
I have used Allegiance for years now and every time I'm still amazed at how courteous and professional they are. Every year I have my R.O. filter changed and my soft water big blue filter changed. They also perform my mist services for the backyard with shutdown for the winter and startup in the spring. 100% recommend them!
Very professional and responsive. No guess work as to when they arrive. Explained everything and cleaned up yard after they were done. Recommend...
Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.
I’ve used this company for multiple services! And they are great at everything they do. They are super responsive to all of my needs and are always on time. I will never use any other company!
They answered the phone (after several other business didnt) and came right out to do the estimate and complete the work. Quality is good. Will call next time I need sprinkler/landscaping work.
I had an exceptional experience with Allegiance today. My old gas water heater needs to be replaced. I called Allegiance yesterday and discussed with David who is very knowledgeable, transparent and told me pros and cons among the different water heaters. I decided to go with 50 gallon Bradford White water heater. Ruben came in next day and clearly explained to me what is the process. He is excellent, very skillful and told me how to maintain it. He cleaned everything afterwards. I am very happy with their services and will call Allegiance for my plumbing issues for sure. Ruben from Allegiance Water Services did an excellent job again today. I had water hammer issue for a couple of months and my pipes coming out the main pipe weren't connected right by a previous plumber. The irrigation system controller needs to be replaced as well And it is now upgraded to an enabling phone control unit. Ruben did an excellent job on replacing the unit and repiping everything. It only took him an hour and they work great! Ruben is very experienced, knowledgeable and efficient. It wouldn't go wrong for Ruben to do your plumbing jobs.
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
Great company. We would highly recommend them. Courteous, professional, fast response time. Very reasonable rates. This is the third time we have used their services and have been very happy every time.
Arrived on time , perfectly described a job he'd be doing and provided excellent service , would recommend him to all of my neighbors, did a great job fixing my water heater leak
