Frequently Asked Questions About Water Heater Repair in South Lancaster, MA
A pilot light that won't stay lit is usually caused by a faulty or carbon-coated thermocouple, a blocked pilot orifice, a defective gas valve magnet, or poor combustion air intake. Call (877) 276-9926 to have a technician test and replace the thermocouple safely.
Yes, dealing with gas combustion requires rigorous safety standards. Our technicians in South Lancaster, MA are fully qualified to inspect gas supply flex lines, sediment traps, draft hoods, and power vent blowers.
Yes. Excessive sediment insulates the tank bottom from water cooling, causing extreme localized heat buildup on the steel. Over time, this thermal stress weakens the steel and causes the tank floor to crack or rupture.
New tank and tankless installations include comprehensive manufacturer equipment warranties (typically 6, 10, or 12 years on tanks and heat exchangers) plus our full local craftsmanship and labor warranty.
When water heats up, it expands by about 2% to 3%. In homes with a backflow preventer or check valve, this expansion creates severe pressure spikes. A thermal expansion tank absorbs this pressure, preventing leaks and protecting your warranty.
