What should I do if my water heater is leaking in Fenton?

Shut off the cold water supply to the tank at the inlet valve on top of the unit first. For a gas water heater, turn the gas control valve to "pilot" to cut the burner. For an electric unit, shut off the breaker at the panel. Don't try to patch a leaking tank. A failed tank body needs replacement, not a band-aid fix. Call us and we'll determine whether the source is a fitting, the pressure relief valve, or the tank itself, and walk you through your options before any work begins.

What We Check During a Water Heater Repair in Fenton, MO

The tank usually gives you notice before it fails. Rust-colored water from the hot tap points to internal corrosion. Rumbling or banging during a heating cycle forces the burner to overheat. A puddle at the base, inconsistent temperature, or a recovery time that's stretched from minutes to half an hour are all worth a professional look.
Our plumbers inspect the anode rod, pressure relief valve, thermostat settings, and burner or heating elements before recommending any repair. Gas units get a thermocouple and gas valve check. Electric water heaters get each element tested with a multimeter. Sediment flushing is part of every maintenance visit. Because our plumbers carry common parts for the major tank brands, most single-component failures are fixed on the same trip.
If repair costs exceed half the price of a new unit, or the tank is past the 10-year mark with multiple problems, replacement usually costs less long-term. St. Louis County's water runs on the hard side, often 10 to 16 grains per gallon, which accelerates anode rod depletion and shortens tank life faster than in softer water regions.

Tank and Tankless Water Heater Replacement in Fenton, MO

Swapping out an old water heater is a good time to make sure the replacement fits how your household actually uses hot water. Conventional tank models in the 40 to 80 gallon range heat and store a large volume continuously. They cost less up front and install with minimal disruption. Tankless water heaters heat water on demand rather than keeping a full tank hot around the clock. That eliminates standby heat loss, cuts energy use, and extends unit life to 15 years or more with proper upkeep, making them a solid long-term option for many Fenton homes.

Hard water is a real factor with either choice. Mineral scale coats the heat exchanger in tankless units and accumulates at the bottom of conventional tanks. Annual flushing clears sediment before it hardens. Tankless systems need periodic descaling to keep the heat exchanger at rated capacity. Our plumbers size the replacement based on your household's actual peak demand, handle any required permits, and coordinate the inspection when the municipality requires one. We install all major brands in gas, electric, and propane configurations. Financing is available for larger projects, subject to credit approval.
