" The technician came on time and was very courteous. Looked at my shower-tub faucet and checked it thoroughly. Explain very well what was wrong with the old, outdated cartridge, which is 15 years old. Give me the choice to replace the whole assembly because they do not make that kind of cartridge anymore. It took several hours, but money well spent. Excellent job and did the cleaning of the bathroom too. I recommended this company and the technician as always. Great job, look as new."

"I had a pipe that was leaking in my wall. Fred was quick to respond to my inquiry and knew exactly what needed to be done. He was kind and explained his plan. As a woman I never felt intimidated. I ultimately went with Carmichael Plumbing and Heating because they also have a guy who could repair the sheetrock. This saved me more stress and research! I highly recommend Carmichael!"

"Sam from SI Plumbing was amazing. He quickly fixed a clogged sink in my home and provided fast, professional plumbing service. Later that same day, I had an additional drain issue in another bathroom, and Sam came back out after 5 PM to take care of it — true same‑day service, which is hard to find. Sam was professional, efficient, and knowledgeable, and he took the time to explain what caused the clog and shared helpful tips on how to prevent future drain problems. It’s clear he takes pride in his work and genuinely cares about his customers. If you’re looking for a reliable local plumber who offers quick response times, drain cleaning, and honest service, I highly recommend SI Plumbing. They’ve earned a spot on my go‑to list for future plumbing needs 100%. "

FAQs for water heater repair or service projects in Hartford, CT

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.
