Preventative maintenance can extend the life of your water heater and prevent costly repairs.

Water Heater Leak Detection and Repair in St. Peters, MO
A leaking water heater can cause serious damage to your home's flooring and foundation, and moisture problems get worse the longer a leak runs.

Leaking Water Heater Repair in St. Peters, MO
Not every leak means a dead tank. Drips from the relief valve, drain valve or supply connections are repairable for a reasonable cost. A leak from the tank body or the bottom seam, however, usually means the inner lining has failed. We pinpoint the source, protect your floors and give you a straight repair or replace recommendation.

Water Heater Pilot Light Issues in St. Peters
A pilot light that won't stay lit is a common problem for gas water heaters, often indicating a faulty thermocouple or gas supply issue. Our experts can diagnose and repair these components, ensuring your pilot light remains lit and your water heater functions correctly in St. Peters. We put your safety first with all gas appliance repairs.
Anode Rod Replacement in St. Peters, MO
The anode rod sacrifices itself so the steel tank does not rust. In hard water it can be eaten away within a handful of years. We pull and inspect the rod, then install a magnesium, aluminum or powered anode depending on your water and any odor problems. A rotten egg smell from hot water often goes away with the right anode choice.

Repair vs Replace Cost Comparison in St. Peters, MO
A typical repair costs $150 to $600, while a new standard tank installed often runs $1,400 to $2,800 depending on size, fuel and code updates. If your heater is under eight years old and the tank is sound, repair is generally the better value. Past ten years, or with a leaking tank, replacement often saves money over time. We give you both numbers so you can decide.

Frequently Asked Questions About Water Heater Repair in St. Peters
Most water heater repairs run between $150 and $600. Thermocouple and element replacements sit at the lower end, while gas control valves and tankless sensors cost more. We quote the full price before starting.
Regular maintenance, including annual flushing of the tank to remove sediment, checking the anode rod, and inspecting the pressure relief valve, can significantly extend your water heater's lifespan and prevent many common issues. Ask about a maintenance plan with FGV Plumbing.
FGV Plumbing repairs all major brands of water heaters, including but not limited to Rheem, Bradford White, A. O. Smith, State, Noritz, Rinnai, and Bosch. Our technicians are trained and experienced with the specific components and repair procedures for a wide range of models and manufacturers.
This often depends on the age of your water heater, the cost of the repair, and the extent of the damage. If your unit is over 10 years old, frequently breaks down, or the repair cost is more than half the price of a new unit, replacement might be more cost-effective in the long run. Our plumbers can help you compare your options.
Tank water heaters often last 8 to 12 years, but hard water can shorten that without regular flushing. Groundwater from limestone areas is especially hard, which makes softeners and regular water heater flushing worthwhile. Tankless units can last 15 to 20 years with yearly descaling.
That smell typically comes from a reaction between bacteria in the water and the magnesium anode rod. Swapping to an aluminum zinc or powered anode and flushing the tank usually solves it.
A leak from a valve or fitting is urgent but generally fixable. A leak from the tank body can worsen fast, so shut off the water supply and power or gas and call us right away.
Repairing is usually more cost-effective for newer units with minor issues. Replacement is often recommended for older units (over 10 to 12 years), those with significant tank leaks, or when repair costs approach the price of a new unit. We'll help you choose the best option for your situation.
