"I had a whole house water softener installed and I am extremely happy with the entire experience. Scott gave me a great price, half of what Culligan charged me. The installers, Brian and Thomas did an outstanding job with the install. They hid the pipes neatly and were very careful and respectful of my home. They explained everything in detail and answered all our questions. This is a great company to work with!"

"Gus at Pro Bright went above and beyond on a Sunday to detect and repair our master bedroom ceiling leak. With water to the house turned off at the street we were desperate to find a contractor who could respond right away. Other contractors offered appointments Monday or Tuesday. Gus responded that he could be here in 2 hours to repair the leaking pipe, but could have Jeff, his water mitigation project manager here within 30 minutes to assess the water damage. These guys were both so professional. They shared the process, timeline and costs, and were prepared to start right away. They promptly moved my disabled husband and his adjustable bed to another room away from the work area assuring his comfort and safety. Gus repaired the overhead leak and turned the water back on. Jeff scheduled the water mitigation process to begin first thing Monday morning. We are especially grateful for the kindness these 2 professionals showed us in our time of need."

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"Both the main and secondary condensate drains were clogged and the service technician cleared them. He also cleaned filters and verified proper operation of all equipment. We intend to use Carini for future annual checkups and needed service.

"Robert expertly found the leak in the garage came from the air conditioner compressor, unit in back patio. The pipe ran all the way under the slab, I guess, through to the garage. We covered the area with a plastic tarp and stopped the water flow. What a relief!"

"Aztec H2O provided a high quality water softener and the install was impressive. Stephen, the owner was very meticulous and took his time to explain the function of the Pentair unit. Best of all, he was a fraction of the cost of other water systems like EcoWater, Culligan, and Life Source! Please call Stephen first!"

"A leaking angle stop flooded my bathroom. They replaced the stops and put me in contact with a company to repair the water damage. The work was done quickly, competently, professionally and expensively. I later had all the remaining 7 angle stops replaced in my house by another plumber for less than half the price. But My Plumber was available and promises to be available immediately, and for an emergency repair I'm willing to pay the price. I have used My Plumber on 2 other jobs where time and expertise were critical, and they did the job well each time. On projects you can plan in advance, they may not be the best choice, but when you need work done immediately, they can come through. And they're a big company that can draw on experts for complicated projects than individuals plumbers may not be able to handle."

"I contacted Anderson Plumbing Heating & Air, a honest and trustworthy company after I realized at the last minute I needed a refrigerator water line assessment and they quickly sent Miguel to my home who noticed upon assessment inspection the water pressure was unsatisfactory and recommended replacing the water pressure valve in addition to the refrigerator water line. Miguel was absolutely amazing , a breath of fresh air, very easy to work with, and managed to accommodate my water line hookup needs fitting me into his busy schedule. Miguel provided me with a great service experience at very reasonable price! He went above and beyond providing before and after pictures of my old and new water setup, answers all of my questions, all while providing outstanding customer service with a smile & 10/10 quality of work! Thank you Miguel for a great refrigerator water line hook up experience !!"
