Plumbing Installation Services in Scottsdale & Phoenix, AZ

Allegiance Water Services are prompt, thorough, and professional. I found them when they did work on my next door neighbor’s irrigation system. When my irrigation started leaking and watering weeds, I called Allegiance Water Systems for a quote and then to schedule repairs. They send text messages and emails with links to track your technician or to call them direct. Invoicing is quick and easy to access via their billing system. You have everything in writing with links to confirm, deny, or modify your service needs.

Installed water softener

He installed a water softener system and did a great job. He also updated our r/o system. Very professional

Friendly, knowledgeable and efficient.

John was great. Professional and courteous. Very pleased with his work.

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.

He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.

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!

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!

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.

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.

David was terrific to work with to get my endless questions answered and align on the right water softener system. Lawson, who installed the water softener was outstanding. He explained service and care issues and did a very professional install. The whole team takes their customers satisfaction seriously. I'll be back for future plumbing needs!

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.

Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.

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.

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!

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

Paul is all of the above plus irrigation systems technologically advanced.

Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.

Paul and Allegiance are the best!

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.

Technician was here within 30 minutes. Did a great job for a fair price. I highly recommend Allegiance…..

Assessed my sprinkler system. Told me and showed me the main issue I'm having. No charge! Very nice and knew the answers to my questions. Didn't try to sell me anything. Will have these guys over everyone else I've done business with.

Allegiance Water Services was great! They prioritized my urgent request and Lawson was great when he came to diagnose the issue. He thoroughly explained the problem and gave me different options and advice on future work. 5 star support!

Josh and the office and service tech Rommel were excellent in every way! Professional, knowledgable service of issues with my water softener.

We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.

Looking into my options as soon as I hear back about my options

Excellent service. Rommel was very professional. I will call on them again. Marc C.

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!

Excellent service and water quality!!

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.

Annual service on RO water system. Rommel was friendly, fast and professional.
