Plumbing Installation Services in Scottsdale & Phoenix, AZ

Would highly recommend. Lawson was very professional.

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.

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.

Johnny Gonzales was very professional, courteous, and thorough.

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!

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

Friendly, knowledgeable and efficient.

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 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 has been great. Eloy was perfect. I recommend this company highly and will certainly continue to use them in the future.

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!

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.

Lawson Key was very professional, respectful and kind. He did a great and solid job of installing a new faucet for our water filtration system!

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.

Fast, reliable. Polite repair people. Fair price.

Excellent communication. Reliable.

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!

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

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!

Highly recommend for Navien install and servicing.

Very smooth transaction! One phone call got the osmosis and softner system scheduled and an experienced technician came and installed both within 2 hours! Great experience. Thank you!

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 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.

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

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.

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

Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.

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.

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

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.

They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service

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