"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"We had an absolutely fantastic experience with them! From start to finish, everything was handled with professionalism, kindness, and clear communication. They showed up exactly when they said they would, explained every step of the process in a way that was easy to understand, and made sure I felt confident about the work being done. The quality of their work was outstanding. you can tell they truly take pride in what they do. They were respectful of my home, worked efficiently, and left everything clean and tidy when they were done. On top of that, the pricing was fair and transparent, with no surprises. It’s rare to find a company that delivers this level of service across the board, and I’m genuinely grateful for how smooth and stress-free the whole experience was. I highly recommend them to anyone in need of plumbing services! For context, we did a full home re-pipe that entailed installing all new plumbing throughout the house. It was no small job"

"Stephen was great, my tub backed up with water and my toilet would not flush, turns out my septic field needed replacing. Very responsive, reasonably priced and best of all. I didn’t have to leave my home during the repairs. I’d give 10 stars if I could."

"I was searching for a Plumbing service that could repair a toilet wax-seal and fix the flooring around it that had warped. Unfortunately, the service tech said that Roto-Rooter doesn't do Carpentry work. He did assess the problem with the project and was very knowledgeable about his craft and gave me the information that I needed to get the repairs done elsewhere... but no references due to liability reasons."

"I had three interactions with this company. First, on Thanksgiving Day, one of the owners of the company responded to a call and helped troubleshoot a problem over the phone. Second, a service person made a repair to the well system. Third, an office manager called me for payment. In all interactions, the company representative was courteous and professional. The repair made, replacing the pressure tank, was completed well, though in my opinion, very overpriced. However, the repair technician said there was an additional problem in the well, and that if it was deep, they could not fix it. I had to call a second well company to make that repair (Claytons in Fountain Inn, who came quickly and made the repair for a very good price). I think it was reasonable for Pretty in Pink to defer this problem, though it turned out that the well pump was not deep, 80 feet. Bottom line, this company's people were good to work with. However, for well work, they are not able to complete my full service, and I think their rates are too high."

"I cannot praise Chad and Claudis from C&C Plumbing and Electrical LLC enough for their outstanding service installing my water heater. From the moment the gentlemen arrived, it was clear that professionalism and expertise were their work ethic. Not only were they punctual, but their knowledge and skillset were truly impressive. I got out of these gentlemen's way and let them go to work. The installation process was seamless, and their attention to detail was on point. They worked efficiently with time, ensuring everything was functioning and looked great after installation. What impressed me the most was their dedication to customer satisfaction. These gentlemen went well above and beyond to exceed my expectations. Despite being a small business, Chad and Claudis provided a level of service that far surpassed anything I've experienced with the larger named companies in the area. Their commitment to doing what's right and not racking up unnecessary billing was shown in every aspect of their work, from start to finish. Their professionalism extended to the end of the installation with the cleanup process, leaving no mess behind. My water heater installation was completed perfectly, and I am beyond satisfied with the results. Chad and Claudis have earned my highest recommendation, and I will, without any doubt, turn to them for any future plumbing or electrical needs. C&C Plumbing and Electrical LLC stands out for all the right reasons in a market filled with big names. Thank you, Chad and Claudis, for your exceptional service and for exceeding my expectations. I am happy with no regrets for reaching out to you and trusting you with your business."

FAQs for water heater repair or service projects in Seneca, SC

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
