"We use Laury for repair and maintenance of our heating and cooling units for our rental properties and each time we need something done, the staff at Laury never cease to provide quality service. The technicians are always knowledgeable, thorough, courteous and pleasant. We recently had an HVAC system installed in one of our units and the home is rather large and is over 100 years old and there was not a whole lot of empty space to work with. The guys at Laury were able to install the system and all of the duct work and components involved neatly with the age and make-up of the home in-mind. They were pleasant throughout the entire installation which took almost a week. They were always on time and always communicated the process with us. Laury is a trusted business with many years of experience behind them. Prices are also extremely reasonable given the cost of services right now. Warren you are the man!"

FAQs for water heater repair or service projects in Williamstown, NJ

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.
