"Daigle were quick to reach out to quote me for the work we needed - replace a water heater and arrived early! Very personable, professional. However, pricing was an issue. They were way outside of what other plumbers charge for this service and way outside of what Angi's has listed as average project costs. They did have an opening for next day installation which would have been fantastic but I couldn't justify the additional $2400."

FAQs for water heater repair or service projects in Merrimack, NH

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.
