Plumbing, Water Treatment & Irrigation Services

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.

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!

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.

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

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

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

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.

Highly recommend for Navien install and servicing.

Fast, reliable. Polite repair people. Fair price.

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.

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.

Installed water softener

Friendly, knowledgeable and efficient.

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

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

Excellent job! Will use them again.

Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.

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.

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!

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

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.

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!

Friendly and reliable. Does great work!

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

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

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!

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

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

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

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.

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.

Fixed my backyard sprinklers without having to put a whole new system in.
