Gas and Electric Water Heater Checks in St. Louis, MO
Whether your home in St. Louis, MO uses a gas or electric hot water tank, our maintenance covers the specific needs of each. For gas units, we inspect burner assemblies, gas lines and vent systems for safety and efficiency. For electric units, we check heating elements, wiring and thermostats. Our detailed checks ensure all energy sources are operating correctly and safely.

Bradford White & Rheem Tank Maintenance in St. Louis
We are experienced in maintaining all major hot water tank brands, including popular models from Bradford White and Rheem, commonly found in St. Louis homes. Our technicians are familiar with the specific components and maintenance requirements for these brands, making sure your unit receives brand-specific care. We use correct parts and techniques to keep your system running well.
Electric Element and Thermostat Service in St. Louis
Electric tanks rely on upper and lower heating elements that get crusted with scale in hard water. We test each element with a meter, check the thermostats and look for scorched wires at the terminal block. If an element has failed we replace it with the matching wattage and voltage. Plenty of families who think they need a new heater just need a lower element and a flush.
Gas Burner and Venting Tune-Up in St. Louis, MO
On gas tanks we clean the burner, inspect the thermocouple or flame sensor and look for soot, rust flakes or scorching around the combustion chamber. We check the draft hood and vent connector for proper slope and secure joints. Dust and lint from garages can block the flame arrestor screen on newer FVIR models, which causes the pilot to drop out. A clean burner gives a stable blue flame and lower gas bills.
Standard Hot Water Tank Tune-Up in St. Louis
FGV Plumbing offers a thorough tune-up for conventional hot water tanks, focusing on critical components. This includes draining the tank to remove sediment buildup, which is essential wherever water carries minerals, and inspecting the anode rod for signs of corrosion. We also check heating elements, thermostat settings and all pipe connections for leaks. Our goal is to optimize your tank's performance and prevent future issues.
Pressure Relief Valve Testing in St. Louis
A properly functioning temperature and pressure relief (T&P) valve is a crucial safety device for any hot water tank. Our technicians will test this valve to confirm it's not stuck or leaking, preventing dangerous pressure buildup within the tank. We verify it opens and closes correctly, and if it fails, we will recommend immediate replacement to keep your St. Louis home safe and compliant with plumbing codes.
Commercial and Rental Tank Maintenance in St. Louis
Property managers, restaurants and small offices often run several tanks that work much harder than a home unit. We set up scheduled maintenance for landlords and businesses, flushing each tank and logging the anode condition and valve test date. Records like these help with insurance and with planning replacements before a tank fails during business hours. We service 50 to 100 gallon commercial models as well as residential tanks in rental units.

Burner and Pilot Light Maintenance in St. Louis, MO
For gas hot water tanks, proper burner and pilot light operation is essential for efficient heating. Our service includes cleaning the burner assembly to remove dust and debris that can impede combustion. We also check and adjust the pilot light, ensuring it ignites reliably. This attention to detail prevents common issues like intermittent hot water or complete heating failure, which can be stressful for homeowners in St. Louis, MO.

Frequently Asked Questions About Hot Water Tank Maintenance in St. Louis
A standard flush and inspection typically runs $125 to $250 depending on tank size and access. Anode replacement usually adds $75 to $200 in parts and labor, and powered anodes cost more.
In mineral-heavy water a magnesium rod may last three to five years. We measure it at every visit so you replace it before the tank lining starts to rust.
Regular, professional maintenance can often be a condition for keeping your manufacturer's warranty valid. Check your warranty documentation, but in most cases, proof of annual service can help keep your warranty intact.
Many manufacturers, including Rheem, A.O. Smith and Bradford White, expect regular maintenance and can deny claims for sediment damage. Keeping service records protects your warranty.
Our technicians are trained to service all major hot water tank brands, including Rheem, AO Smith, Bradford White, State, Kenmore and more. We have the know-how to handle various models, whether gas or electric.
Common signs include reduced hot water supply, strange noises like rumbling or popping, rust-colored water, a sulfur or rotten egg smell, or water leaking from the tank. These point to issues that maintenance can often resolve.
While some basic steps like draining a small amount of water can be done by a homeowner, professional hot water tank maintenance involves specialized tools and experience to properly inspect electrical or gas components, anode rods and pressure relief valves. It is best left to a professional to ensure safety and code compliance.
Routine hot water tank maintenance, such as flushing and inspections, typically does not require a permit in St. Louis. However, if major components are replaced or the entire unit is swapped out, a plumbing permit may be necessary. Our team takes care of all necessary permit applications.
