Fast and reasonable.






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.

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!



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

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.

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!!!

Friendly, knowledgeable and efficient.

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.


Very professional and responsive. No guess work as to when they arrive. Explained everything and cleaned up yard after they were done. Recommend...

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

Paul and Allegiance are the best!

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!





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

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


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


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


Excellent service

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!


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.



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.

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

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!

These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality


Great company! My water heater and water softener both decided it would be best to stop working on the same day. Allegiance came out and gave me a quote for both and their price was great. I feel like they were really interested in helping me.

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.

Excellent service and water quality!!

Excellent communication. Reliable.


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

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

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

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

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.
