Get matched with top water treatment pros in Chino Hills, CA

"Very happy with my new 3-stage whole house water filter/installation - topnotch!!!"

"I recently had the pleasure of working with Joshua at Diamond House, and I couldn't be happier with the experience. From start to finish, he demonstrated professionalism, efficiency, and excellent customer service. My pipes were old, corroded, and causing issues in almost every part of my house from faucets to my water heater and water pressure. When I reached out for a repiping project, they responded quickly and scheduled an in-home consultation right away. Their team was punctual, arriving exactly when they said they would. Joshua walked me through the process of replacing my aging pipes and even gave me a few options that fit my budget. If any unexpected issues came up (as they sometimes do with older homes), he discussed them with me before proceeding. This level of communication gave me peace of mind. Although repiping is a significant investment, I felt that their pricing was fair for the high level of service I received. The long-term benefits of upgraded plumbing have already made a difference in my water pressure and quality. They also provided a warranty on all of their work and included yearly maintenance on my water heater and water filter/descaler. Diamond House Plumbing exceeded my expectations, and I would highly recommend them to anyone in need of repiping or other plumbing work."

"My under the sink RO system stopped working. Daniel came and we realized it needed to be replaced. He made a recommendation and bought all parts for me. It was a smaller direct system that works best for my needs."

"The plumber was very knowledgeable and professional. They kept the job site clean and we are very happy with the results."

"Authority came out to service my tankless water heater, and I?m really impressed with the experience. Chris was the technician who handled everything, and he made sure to explain how the system works and what needed to be done. He performed a thorough cleaning, checked all the components, and made sure everything was running efficiently. He was professional, knowledgeable, and took the time to answer all my questions. My water heater is running like new again! I?m very happy with the service and will definitely call them again for any future needs. Highly recommend!"
