Plumbing, Water Treatment & Irrigation Services

Friendly, knowledgeable and efficient.

Will make sure the job gets done!

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

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

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.

The service tech was pleasant, courteous and knowledgeable. He tracked down the problem and eliminated it as quickly as possible, as he was aware that what his time cost us in getting the job done.

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.

Fast and reasonable.

Installed water softener

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

Excellent service and water quality!!

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.

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

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!

Excellent communication. Reliable.

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!

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.

Fast, reliable. Polite repair people. Fair price.

I had an exceptional experience with Allegiance today. My old gas water heater needs to be replaced. I called Allegiance yesterday and discussed with David who is very knowledgeable, transparent and told me pros and cons among the different water heaters. I decided to go with 50 gallon Bradford White water heater. Ruben came in next day and clearly explained to me what is the process. He is excellent, very skillful and told me how to maintain it. He cleaned everything afterwards. I am very happy with their services and will call Allegiance for my plumbing issues for sure. Ruben from Allegiance Water Services did an excellent job again today. I had water hammer issue for a couple of months and my pipes coming out the main pipe weren't connected right by a previous plumber. The irrigation system controller needs to be replaced as well And it is now upgraded to an enabling phone control unit. Ruben did an excellent job on replacing the unit and repiping everything. It only took him an hour and they work great! Ruben is very experienced, knowledgeable and efficient. It wouldn't go wrong for Ruben to do your plumbing jobs.

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

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

Excellent job! Will use them again.

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

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

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.

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.

Paul and Allegiance are the best!

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.

Paul is all of the above plus irrigation systems technologically advanced.

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

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