Plumbing, Water Treatment & Irrigation Services

Allegiance is fantastic. Lawson in particular is a total professional. Super knowledgeable, trustworthy, and efficient. Diagnosed our crazy irrigation issues and came up with a cost effective solution.

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!

Assessed my sprinkler system. Told me and showed me the main issue I'm having. No charge! Very nice and knew the answers to my questions. Didn't try to sell me anything. Will have these guys over everyone else I've done business with.

Lawson with Allegiance Water has done work for us the last few times and he’s very polite and professional and has done great work for us!

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.

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

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

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.

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

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 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!

I had made an appointment for Thursday, but was pleasantly surprised to receive a call on Wednesday that Eloy could come out a day early. They serviced my RO water system and soft water system. They exhibited excellent attention to detail and worked in a professional manner. When finished they cleared explained what we needed to to do move for the coming year. I will certainly use them again for annual inspections and servicing.

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!

Fast and reasonable.

Will make sure the job gets done!

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

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

Excellent service

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 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.

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.

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

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!

Friendly, knowledgeable and efficient.

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

Highly recommend for Navien install and servicing.

Excellent communication. Reliable.

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

Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.

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