"I hired Marcin & his team at Precision Plumbing & HVAC for multiple projects. First to handle all plumbing in a gutted bathroom renovation, then to replace an old gas water heater and furnace with a new high efficiency combi boiler. I've since recommended them to friends and family and would absolutely do so again."

"This company has been awesome. I am a Worcester resident and have no clue about heating systems. David Clay and his team came out to look at my boiler. It was not firing. Winter is fast approaching. David provided a free estimate and also encouraged me to look at quotes from other competitors. I did. And his pricing was best aligned with my budget. His quality of work is amazing. David and his technicians fielded all my questions- I had many. Their customer service is amazing as they had all the patience and courtesy to educate me about the work and boiler systems. My experience as a customer is that Clay Plumbing Heating offers the best quality, professional craftsmanship, best client service, and at the best rates."

"Milltown was exceptionally responsive (before, during and after) the work was performed. Across the Milltown organization, they were responsive to my questions about water heater selection; Mike was responsive and a partner in selecting the best location for the new unit and after, Milltown and Mike were immediately responsive when part of the unit was not operating as expected. Milltown is a solid organization that takes pride in their work."

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

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