Plumbing, Water Treatment & Irrigation Services

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!

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.

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.

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!

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.

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

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

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.

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.

Will make sure the job gets done!

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

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

They answered the phone (after several other business didnt) and came right out to do the estimate and complete the work. Quality is good. Will call next time I need sprinkler/landscaping work.

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.

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.

Excellent service

Installed water softener

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

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

Johnny Gonzales was very professional, courteous, and thorough.

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

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.

Highly recommend for Navien install and servicing.

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

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

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

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!

Paul and Allegiance are the best!

I’ve used this company for multiple services! And they are great at everything they do. They are super responsive to all of my needs and are always on time. I will never use any other company!

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.

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!
