"Damien made time for me on short notice. When he arrived I described the issue and he was quick to correctly diagnose the cause. He had to replace a heating coil in my electirc water heater. During the course of the repair he noted that the drain valve was not working properly. He replaced that as well. Before he left he drained and flushed the tank. All is working well. I'd recommend Damian for this type of service. Damian was delayed because of an earlier appointment where materials had not arrived on time. He worked later that normal working hours to make sure my problems were taken care of. I cetainly appreciated his efforts and that he kept me informed of his arrival time. He did not have to extend his day to the extent he did, but rather than re-schedule me, he completed my job as promised."

"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."

"I am a long time customer who pays Rodenheiser a monthly fee which covers annual maintenance and some priority in the event of any necessary repair required. I had an a/c compressor failure. I had to wait 3 weeks to have a technician visit and tell me that the unit’s motor was dead and the compressor needed replacement. Then, after ordering a new compressor, which was available within 3-4 days I was scheduled for an installation 3+ weeks later. I had to complain strenuously and threaten to cancel the order to get the installation moved forward to within 10 days. Apparently being a long time customer and paying a monthly fee for better service means absolutely nothing. The installation went well. Not sure about future relationship."

"The technician and electrician were both very respectful, knowledgeable, provided all options, were open and honest about why they recommend the service chosen, helped in obtaining the financial services, walked me through the entire process. The technician went above and beyond making sure the. After the water heater install was completed he performed a safety inspection on my heating system, cleaned the debris from the flute into the chimney, made a few tweaks here and there to make sure my system was performed to his satisfaction. I was extremely appreciative of his care, concern and professionalism."

"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."

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.
