Flammable Vapor Sensor Repair in Millsboro
Most gas water heaters built in recent decades have a flammable vapor ignition resistant design. A sensor or flame arrestor screen shuts the burner down if it detects vapors or overheating. Lint and dust in garages can clog the arrestor and trip the system. We clean the combustion chamber and replace sensors or thermal switches as needed.

Gas Water Heater Noise Troubleshooting in Millsboro
Odd noises coming from your gas water heater, such as rumbling, popping or whistling, often indicate sediment buildup in the tank or a burner problem. Hard water can speed up sediment accumulation. Our repair service includes flushing the tank and inspecting for sediment, addressing pressure issues or checking other components that might be causing the noise, improving efficiency and quiet operation.
Propane Water Heater Repair in Millsboro
Rural properties often run water heaters on propane instead of natural gas. Propane units use different orifices and regulator pressures, and improper conversions cause sooting and poor performance. We confirm the correct parts are installed and repair pilots, valves and burners. We also check tank regulators for correct pressure.
Gas Valve and Thermostat Repair in Millsboro, DE
Issues with the gas valve or thermostat can lead to uneven water temperatures or a complete lack of hot water. Our team can test these key components for proper operation, checking for electrical continuity and gas flow. If a part is defective, we will replace it with a quality, manufacturer-approved component so your water heater heats efficiently and safely.
Burner Cleaning and Repair in Millsboro, DE
A yellow, lazy or noisy flame signals a dirty burner or poor combustion air. We remove and clean the burner, check the orifice size for natural gas or propane and adjust as needed. A clean blue flame heats faster and produces less carbon monoxide. We also check for rust flakes dropping from the flue.
Gas Water Heater Code Compliance in Millsboro, DE
Any repair involving gas appliances must follow strict local and state plumbing codes. GNV Plumbing makes sure all gas water heater repairs in Millsboro, DE are performed in full compliance with current regulations. This includes proper venting, gas line connections and seismic strapping where required. Our attention to code ensures not only safety but also a smooth path through any future inspections.
Venting and Draft Repair in Millsboro, DE
Atmospheric gas water heaters rely on a properly sloped metal flue to carry exhaust out of the home. Disconnected sections, rusted draft hoods and poor slope can let combustion gases spill back. We repair or replace vent sections and verify draft with a test. Proper venting is essential for your family's safety.
