How can I tell if my water heater needs repair or a full replacement?

Start with age. You'll usually find the manufacturer date on the label or encoded in the serial number. Under eight years old with a heating problem? Odds are good it's caused by a faulty part we can swap out. If it's over 10 years old and you're dealing with rusty hot water, rumbling noises, or moisture around the base, you probably need a new unit. A leak from the tank body itself always means replacement. If you're not sure, we'll inspect it and give you both prices so you can compare.

How long do water heaters last in Franklin County homes?

You can expect to get eight to 12 years from a standard tank and close to 20 from a well-kept tankless unit. However, the area's hard water pulls those numbers down. Mineral scale insulates the bottom of the tank from the burner or coats electric elements, so the heater works harder for less hot water. Flushing the tank once a year and checking the anode rod every few years can add real time to its life.

Can you repair tankless water heaters?

We can. Our plumbers descale heat exchangers, clean inlet filters, replace igniters and flow sensors, and clear the error codes that come with them. Most tankless problems in this area trace back to scale, so we'll also talk with you about a maintenance schedule (or a softener) to keep it from coming back.

Is water heater repair something I can do myself?

Flushing the tank or checking the relief valve is fair game for a handy homeowner. But anything involving gas valves, burner assemblies, venting, and electrical work is a different story. Mistakes there can lead to gas leaks, carbon monoxide, or scalding water, and they can void the manufacturer's warranty. If the fix involves gas or 240-volt wiring, call a licensed plumber.

About Our Services for Water Heater Repair and Water Heater Replacement in St. Clair, MO

Most tank problems come down to a short list of parts. On gas units, it's usually a worn thermocouple, a dirty pilot assembly, or a gas control valve that's stopped responding. Electric heaters tend to lose an upper or lower heating element, or a thermostat that won't call for heat. We test each part instead of guessing, ensuring we solve the issue. A pilot that keeps going out after a windy night usually has issues with a draft or a weak thermocouple, not a dying heater. Hard water across Franklin County adds its own trouble. Limestone and dolomite under the region load the water with minerals, and that scale settles at the bottom of the tank. You'll hear it first: popping and rumbling during heat cycles. A flush clears it if the buildup hasn't gone too far. We'll also check the anode rod, since a spent rod is the main reason tanks rust from the inside out. Replacing one costs far less than a new heater. Before we leave, we test the temperature and pressure relief valve and confirm the unit is heating to a safe setting, usually around 120 degrees.
Tankless units last longer than tanks, often close to 20 years, but they don't forgive neglect, especially when it comes to mineral scale. It coats the heat exchanger, causing the unit to overheat, and you may start seeing error codes or water that swings from hot to lukewarm mid-shower. Our plumbers descale the exchanger with a pump and flush kit, clean the inlet filter, and check flow sensors, igniters, and venting. Most units around here need that flush about once a year. On gas models, we look at the gas supply too, since an undersized line causes a lot of the "it works until two showers run" complaints. We work on most major tankless brands, including Rinnai and Navien, and we'll tell you honestly when a repair isn't worth the money anymore.
Some heaters can't be saved. A leaking tank is the clearest sign, because once the steel liner fails, no part will fix it. Age is the other. Most tank heaters in this area fail between years 8 and 12. When it's time for water heater replacement, our St. Clair plumbers size the new unit to your household, not to whatever was sitting there before. A family of five that kept running out with a 40-gallon tank probably needs a 50-gallon tank or a tankless upgrade. Thinking about switching from electric to gas, or from a tank to tankless? We'll walk you through the venting and gas line work first. We install gas, electric, and tankless models. Each install includes a new expansion tank where code calls for one, new supply connections, proper venting on gas units, and a drain pan where the heater sits above finished space. We haul the old tank away too.

To Repair or Replace? How We Help You Decide What’s Best for Your Water Heater Situation

Nobody wants to buy a water heater they didn't need. And nobody wants to pay for a $300 repair on a tank that springs a leak three months later. So we give you the facts and let you make the call.

Here's the rough rule we use. If the heater is under 8 years old and the problem is a part (element, thermostat, thermocouple, valve), repair almost always wins. If it's past 10 years, rusty water is coming from the hot side only, or there's water seeping from the tank itself, replacement is the better spend. The gray zone is years 8 to 10. In that range, we look at the condition of the anode rod, how much sediment is in the tank, and what the repair costs are compared to a new unit.
