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 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.

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

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!

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.

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!

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.

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.

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.

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.
