Water Heater Maintenance and Tune-Ups in O'Fallon, MO
Preventative maintenance can extend the life of your water heater and prevent costly repairs. We offer tune-up services that include flushing sediment from tanks, checking anode rods, inspecting connections, and testing safety features.

Regular service helps control mineral buildup and keeps your unit running efficiently year-round in O'Fallon, MO.

Gas Water Heater Repair in O'Fallon, MO

Water Heater Pilot Light Issues in O'Fallon
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, making sure your pilot light remains lit and your water heater functions correctly in O'Fallon. We put your safety first with all gas appliance repairs.
Anode Rod Replacement in O'Fallon, 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 usually goes away with the right anode choice.
No Hot Water Diagnostics in O'Fallon
When your water heater isn't producing hot water, the cause can range from a simple pilot light issue to a complex electrical problem or a major component failure. Our diagnostic process in O'Fallon is careful, identifying the exact root cause so we can recommend the most effective and affordable repair, whether it's a thermostat, element, or gas valve.
Sediment Flush and Noise Repair in O'Fallon
Popping, rumbling or crackling sounds usually mean a thick layer of sediment is trapping water under it and overheating the tank bottom. We drain and flush the tank, break up scale with repeated fills and check the drain valve for blockage. Flushing restores capacity, lowers energy use and helps extend tank life. We usually recommend yearly flushes for homes on hard water.

Tankless Water Heater Troubleshooting in O'Fallon
Tankless water heaters, while efficient, can experience issues like error codes, flow sensor problems, or mineral buildup from hard water. Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and appliances. Our technicians are well trained in diagnosing and repairing these advanced systems, often using specific tools and diagnostic software to ensure they deliver endless hot water as designed in O'Fallon.

How Our Water Heater Repair Process Works in O'Fallon, MO
From your first call to a working heater, here is how we handle every repair.
Request a Quote
Call (816) 330-2338 and describe what your water heater is doing, including the brand and age if you know them. We schedule a visit, usually the same day.
Test and Diagnose
Your plumber tests the burner or elements, controls, venting and tank condition. You receive a flat price for the repair along with an honest view of the tank's remaining life.
Repair and Verify
We replace the failed part and run the heater through a full cycle. Gas connections are leak tested and the relief valve is checked before we go.
Frequently Asked Questions About Water Heater Repair in O'Fallon
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.
Common signs include a lack of hot water, water that isn't hot enough, strange noises coming from the tank (like rumbling or popping), visible leaks around the unit, rusty or discolored hot water, or a foul odor from the hot water. If you notice any of these, it's best to call a professional.
Tank water heaters often last 8 to 12 years, but hard water can shorten that without regular flushing. Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and fixtures. Tankless units can last 15 to 20 years with yearly descaling.
Most repairs are completed in one visit lasting one to two hours. If a special part must be ordered, we typically have it within one to three business days.
Yes, FGV Plumbing stands behind its work. We offer a warranty on both parts and labor for our water heater repairs. The specific terms will be detailed in your service agreement, giving you peace of mind.
That smell usually 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.
Most standard water heater repairs, such as replacing a heating element or a thermocouple, can be finished within 1 to 3 hours. More complex issues or those requiring specialized parts might take longer, but we strive for same-day resolution whenever possible.
Some handy homeowners do, but mistakes with gas or 240-volt wiring can be dangerous. A licensed plumber also checks venting and relief valve operation, which DIY repairs often skip.
