Get matched with top tankless water heater installers in Walnut, CA

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"It went very well. John was very professional, pleasant, courteous and fast. He even made a trip to Home Depot to purchase faucet tube nipples to prevent future kinking, as was one of the problems with the water pressure that I didn't even realize I had. He also replaced the water valve under the sink for me because the old one was worn and could possibly leak. Absolutely pleased and I would highly recommend."

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"They did a nice job and very fair on cost. I replaced a hot water heater so not the most complex job, but I recommend them."

"I recently had the pleasure of working with Anthony Fankhauser from Rooter Er & Plumbing, and I can confidently say that he is the most professional plumber I have ever encountered. Our search for a reliable plumber began about six weeks ago when Anthony came over to provide us with a free estimate for some work needed in our home. From the start, he impressed us with his prompt response to our request on Angie's List, arriving the same day and offering valuable tips to make our shower remodel efficient and cost-effective. Throughout our interactions with various plumbers, Anthony stood out by taking the time to truly understand our needs and how he could assist us best. Despite the initial consultation not resulting in immediate work, Anthony remained responsive and proactive. Fast forward six weeks, and he was once again quick to reply, reaffirming our confidence in his professionalism. On the day of the job, Anthony arrived on time and efficiently installed our new shower faucet, recommended the best option for our budget, and set the drain in record time, coordinating seamlessly with another contractor working on the floor. Not only did he go above and beyond by addressing additional plumbing issues in our home, such as resealing a leaking toilet tank and replacing faucets, but he also made trips to Home Depot on our behalf without any extra charge. Anthony's dedication to meeting our needs, even outside regular working hours, sets him apart from other contractors we've worked with during our home remodeling project. His attention to detail, professionalism, and unwavering commitment to quality work make him a standout professional in his field. I am typically critical when it comes to service providers, but I cannot fault Anthony in any way. His integrity, work ethic, and genuine care for his clients make him a truly exceptional plumber. If you are in need of a reliable plumber, I highly recommend reaching out to Anthony Fankhauser at Rooter Er & Plumbing. Whether you are in South County or in areas like Marietta, you can trust that you will receive top-notch service and expertise. Thank you, Anthony, for your outstanding work and for exceeding our expectations."

"From the moment I reached out to Flow Master Plumber Inc, it was evident that I was dealing with consummate professionals. The installation of a water softener system can be a daunting task for homeowners like myself, but the team made this process seamless and efficient. I'd like to give special recognition to Wilson, the technician who was assigned to my case. His expertise was evident from the get-go. Wilson was punctual, arriving right at the scheduled time, making sure he didn't disrupt the flow of our daily routine. He wore protective footwear to ensure our floors remained spotless and took the time to lay out his tools and materials neatly. Wilson took the time to explain the entire installation process to me. He detailed the benefits of the water softener system and its mechanics. I was particularly impressed by his patience when answering all my queries. He didn't just aim to install; he aimed to educate, ensuring that I understood not just the 'how', but the 'why' behind every step. The actual installation was flawless. Wilson showcased his seasoned expertise, navigating through challenges with ease. I could tell he treated my home as if it were his own, giving meticulous attention to every detail. Post-installation, he tested the system to ensure it was operating optimally and took me through a comprehensive tutorial on maintenance and troubleshooting. Now, a few weeks post-installation, I can confidently state that the water softener system has been a game-changer. The water feels smoother, tastes better, and I've noticed a significant reduction in limescale buildup on my faucets and fixtures. Our laundry feels softer, our dishes sparkle, and our skin feels more hydrated. All thanks to the top-tier system installed by Flow Master Plumber Inc. But it's not just about the product; it's about the service. The post-installation follow-up by Wilson was an unexpected but much-appreciated gesture. He called to ensure that the system was working as intended and to check if I had any concerns. In an age where it's challenging to find companies that genuinely care about customer satisfaction, Flow Master Plumber Inc stands out as a beacon of excellence. Their commitment to quality, combined with Wilson's unparalleled expertise, has made me a lifelong customer. To anyone considering a water softener system, or any plumbing service for that matter, I wholeheartedly recommend Flow Master Plumber Inc. And if you get a chance, ask for Wilson. His professionalism, expertise, and genuine care are a testament to the values of the company. Thank you, Flow Master Plumber Inc and Wilson, for transforming our water experience. Your dedication to quality service is unparalleled, and I am immensely grateful for the difference you've made in our lives."
