Water Softeners
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.

- Our licensed techs install it

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.

Overall Rating
Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.
These Guys are awesome! They were on time and on the mark. Service was professional and they did a clean repair. I would definitely recommend them.
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
Friendly and reliable. Does great work!
Fast, reliable. Polite repair people. Fair price.
I love this business. They go the extra mile to make sure their clientele are taken care of. My hot water heater went out on New Years eve and required a part to fix it. The part was unavailable and Rheem the manufacturer was closed until Monday. John Gonzales from Allegient brought out a new unit and installed it, so that I would have hot water for the weekend. This is a great company, and I am glad that I selected them. UPDATE Allegiance is my go to water company. My house is 50 years old now, so I'm glad I have them to call if I have a problem. Rommel Valenzuela came today to service my filtration system. He was nice, professional and did a great job.
Fixed my backyard sprinklers without having to put a whole new system in.
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.
Extremely impressed and satisfied with professionalism and service. A real person always available by phone unlike several competitors I tried to reach. Eloy the tech was the best in all respects.
Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.
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!
I had Eloy come by to repair a water softener system that had failed, as well as replace the filter in the RO system. He was courteous, knowledgeable, responsive, timely, and really knew his stuff.
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!
Excellent service. Rommel was very professional. I will call on them again. Marc C.
Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.
Had a hot water heater replaced today; Lawson did a fantastic job. The workmanship is very professional. Lawson was on time and did exactly what he said he was going to do.
I had made an appointment for Thursday, but was pleasantly surprised to receive a call on Wednesday that Eloy could come out a day early. They serviced my RO water system and soft water system. They exhibited excellent attention to detail and worked in a professional manner. When finished they cleared explained what we needed to to do move for the coming year. I will certainly use them again for annual inspections and servicing.
I was in a panic when my sprinklers started making loud noises at 5:30am. I called Allegiance water and was able to get a service rep out the next day. They...
Johnny Gonzales was very professional, courteous, and thorough.
I am so grateful to Lawson for helping me with my spinkler system. He is knowledgeable, kind, and patiently answers all my questions. I trust him and Allegiance Water Service for all of my home’s plumbing needs.
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.
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.
Paul came today to check my Rain Bird system controller. I have worked with him during my new irrigation installation project at the beginning of this year. I was extremely pleased with the outcome then and again today. I specifically requested him for today’s job. As always, he offered excellent, professional service, knowledgeable, courteous and friendly. I would refer him and Allegiance Water Service to my friends with high remarks.
After 5 years we had water softener , we found out we use soft water for our pool and watering the plants in our back yard , so I called this company they responded fast and the next day they sent their technician Ruben . After we agreed on his estimate , he came the next day. He did awesome job on separating our soft water. Ruben was knowledgeable, fast and reliable. I am so happy with his work and recommend him and this company to everyone.
Friendly, knowledgeable and efficient.
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.
They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service
Allegiance’s technician Eloy Garcia arrived promptly, explained and showed me the issue with my water softener and also he noted some water in tray beneath the water heater that I had even noticed. He fixed the motor on softener and then removed and replaced my water heater as he noted it was still under manufacturer’s warranty! I am so please with his prompt, thorough and efficient service. I highly recommend him and Allegiance Eater Services!
Excellent communication. Reliable.
Had an issue with my sprinkler system, something failed and I had a big wet spot on the side of my house. Called in and was helped with instructions on how to turn off the sprinkler side so no water would go to it until a repair could be scheduled. Paul comes out and shows me the problem, we set a time and he fixes all of that, THEN while testing, just waltzes into the spraying sprinklers and dials in where the water SHOULD have been spraying, like " oh, that's the wrong direction to spray for this area..." Then he programs the whole thing to fix my already mediocre lawn and bushes, told me what to do to improve my lawn through yard care and got into his car with soaking pants and thanked ME! 10/10.
Would highly recommend. Lawson was very professional.
Installed water softener
Allegiance has been great. Eloy was perfect. I recommend this company highly and will certainly continue to use them in the future.
Fast and reasonable.
Excellent service
Lawson was incredibly friendly, informative and professional. David was also a standout for his strong communication and customer service. 10/10 would recommend to friends and family.
