"Neo was excellent! My water heater went and a new one was installed by Neo and his team the next day. They were very professional, communicated instantly, and did a fantastic job. Will definitely use S.S Piping n Heat for all of my future plumbing and heating needs. Would recommend this company to anyone!"

"Highly satisfied AGAIN in a second job with Mouradian (hot water heater earlier). This time was a replacement of leaking cast iron sink waste pipe imbedded in the wall/floor between two condo unit bathrooms. Eric Mouradian is very no-nonsense, fast in his estimates, and reasonable in his pricing. The plumber who did the job, Rich, was excellent: friendly, efficient, and clear about what was going on. He understood immediately that his first instinct, to open up the ceiling and wall of the downstairs bathroom should be avoided if possible, to limit wall repairs to one bathroom instead of two. And he then quickly figured out how to do it and did it. The cost was considerably less than the quote of a competitor, who misdiagnosed the problem at first, refused to put his quote in writing, and showed no interest in keeping wall damage to a minimum. No comparison."

"It went very smoothly. There was one minor hiccup that wasn't discovered until after 9pm on the evening of the installation, but we called the 24-hour service line and within 20 minutes, there was a tech back at our house to fix the issue. I would contract H L Bowman to do work for us again in a heartbeat."

"This is my sixth time using the service from Andrew at Local Plumbing and Heating. He is quickly available, efficient and thoughtful. He is trustworthy: I know he will take care of everything I asked for and thinking ahead for great ideas. I used his service for major home projects and I strongly recommend him for everything: from water heater tank replacement to gas lines installations."

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"We have been loyal customers of Genove for years, but this year they exceeded any expectations. From the emergency service call on a cold Sunday night in February to the installation of the new furnace and hot water heater today. Armando and crew are terrific. Ryan, Richie and Shawn completed the project in less time than we expected. And, Armando assisted us in the HEAT loan program which has us paying for this work at zero interest over 7 years as well as handled the rebate programs. Highly recommend Genove!"

"David helped me install Heat Pump Water Heater that I purchased from Home Depot. It was his first time installing a heat pump water heater but he made sure it gets installed as per code and right way. He worked with me to install stop valve in the end."

"A different company gave us a quote for $500 to clean the condenser and $2500 to recharge it to check for leaks, so we were dragging our feet. I decided to get another opinion and found Comfort Doctor. They were incredibly responsive and came the next morning. They cleaned the unit for $65 and recharged the unit right then and there with 1 lb of refrigerant. Now it is working great for ~$300. The technician gave us recommendations as if it were his own home and said the quick and inexpensive fix is where you should start. We might not need to do the more expensive leak-check at all unless the system continues to leak substantially."

FAQs for water heater repair or service projects in Waltham, 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.
