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.

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!!!

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

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 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!

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.

John was on time and professional. He fixed the leak in my backyard system and tested it to make sure no further leaks. He also checked the front yard and found an additional leak that I hadn’t noticed and also fixed it in the same trip. Super happy with the great service and will definitely call these guys again for future plumbing repairs outdoors and indoor.

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.
