"Needed to repair or replace my tankless electric water heater. Many other companies refused to even take a look. Worked with Andy, had to get mine replaced but did it quick and very professional."

"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"When we purchased our home, we learned that the previous owners had Mermaid Water install a water treatment and purification system, as well as the hot water heater. We have never had a home with well/septic or treatment/purification system. We have had Mermaid Water come out on several occasions and each time the technicians have been extremely knowledgeable and friendly and conscientious. They have taken time to not only service our home but they have freely shared their knowledge with us and helped us better understand how the water works in our home. We always feel like we got the value for our money and then some! Brent, Matchett, Jay...have all been incredibly helpful and friendly! The few questions/concerns we've had (mostly due to our ignorance), they have always been willing to follow-up and resolve and resolution has been 110%. Also, they have an amazing customer service approach with their scheduling and notifications and immediate appointments scheduled--you always know who and when they will be at your home, and we love this extra touch!! Thank you Mermaid Water! We HIGHLY recommend!"

"SwiftPro was excellent. When our hot water heater went out (at nearly 20 years old, we were neither upset nor surprised!) we reached out to a few places but SwiftPro was the most responsive and had the price was fair. Zabi, the service technician was fantastic. I can’t say enough good things about him. He was prompt, provided excellent communication, took meticulous care with the work and work space, and was just a great person to talk to. The install went great and there was no aggressive sales tactics or upselling. Just a genuine cut and dry hot water heater removal and install experience. I highly recommend SwiftPro. Thanks Zabi!"

"I called then on a Saturday afternoon after noticing a water leak in my home. A representative came out within 20 minutes. He explained what he was going to do and discussed the fee. Once he found the leak he explained the fee to fix it. He was courteous, wore a mask at all times and kept his shoes covered. He cleaned up after his repair and showed me what he had done."

FAQs for water heater repair or service projects in Gainesville, VA

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.
