"John “Johnny Rocket” & his associate did an amazing job servicing my home in Winchester. From the moment they walked through the door, they exuded a friendly, knowledgeable and professional manner. They were quick to diagnose the issue in my heating system & worked efficiently to fix the issue on the spot. The entire job was complete in under an hour. I needed a new thermostat & John installed one on the spot as well! I highly recommend hiring these two gentleman for any of your plumbing & heating needs. After the job was complete, they even took the time to talk my son & I about how they enjoyed helping residents in the local Winchester Community. (They are both former Winchester High School graduates.) I would give Johnny Rocket 10 stars ⭐️ if I could. Look No Further! -Emily (Long time Winchester Resident)"

"Chris, Matt, and their employees did excellent work for us to replace our combi boiler and on-demand hot water heater. They fit us in quickly before a cold snap and worked long hours to get the job completed. The whole system looks great and they clearly take pride in their work. They have been responsive and timely about any follow-up tweaks to the system to get it running correctly. Their communication has been clear and response time is quick. Would definitely recommend! "

FAQs for water heater repair or service projects in Gloucester, MA

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.
