Water Heater Repair in Oakville, MO: Find the Problem, Fix What’s Fixable
Water heater repair in Oakville tends to start in the bathroom. Somebody turns on the shower, waits, and the water never gets warm. Now you’re wondering if it’s a quick part or a whole new tank, and whether you can wait until the weekend to find out.
TLDR:
- Most “no hot water” calls are one bad part, not a dead tank.
- Electric heaters usually lose an element or a thermostat.
- Gas heaters usually have a pilot, sensor or gas valve problem.
- A leak from the tank body can’t be repaired.
- If you smell gas, leave the house and call Spire first.
The good news is that a lot of these are fixable. Sam Marsala has been fixing water heaters since 1998. His truck carries the common parts, so most repairs get done on the first trip.
He’s also known for telling people when they don’t need to buy a new one. One customer wrote that Sam fixed their water heater instead of selling them a new one. While he was there, he checked their AC too, and explained everything he found.
What Your Water Heater Is Telling You
Below are the calls we get most, and what’s usually behind each one. It won’t replace a visit, but you’ll have a rough idea of what you’re dealing with when you pick up the phone.
No Hot Water at All
On an electric heater, check the breaker first. If it’s on, the safety reset on the upper thermostat may have tripped, or a heating element has burned out. On a gas heater, the pilot may be out, or the part that senses the flame has worn out.
Newer gas tanks have a screen at the bottom that lets air in for the burner. In basements with a dryer nearby, that screen can clog with lint, and the heater shuts itself off. It looks like a broken water heater, but it’s often a cleaning job.
Hot Water Runs Out Fast
An electric heater has two elements, one up top and one down low. When the lower one dies, you still get hot water, just a lot less of it. On gas heaters, a thick layer of sediment on the bottom can do the same thing, and so can a broken tube inside the tank that sends cold water to the wrong place.
Popping, Cracking or Rumbling
Almost always, that noise is sediment. Our water leaves minerals behind, they pile up in a crusty layer on the bottom, and little pockets of water get stuck underneath. When the burner kicks on, those pockets flash to steam and pop. On a younger tank, a flush often quiets it down, but on an old one it means the end is getting close.
Water Around the Base
Find where it’s coming from before you panic. A drip from the drain valve, a fitting on top or the relief valve pipe is usually a repair. If the relief valve keeps dripping, the pressure in your pipes may be too high, and that’s fixable too.
If the water is coming from the tank itself, the steel has rusted through. No part fixes that. At that point the honest answer is getting a new tank in the right way, and the sooner the better.
A Smell Like Rotten Eggs
This one has two very different causes, and you need to know which one you have. Run the hot tap and sniff. If the smell is in the water, the culprit is usually a metal rod inside the tank that reacts with bacteria in some water supplies. It stinks, but it won’t hurt you, and putting in a different kind of rod usually ends it.
Smell it in the air near the heater, or anywhere else in the house? Then treat it as a gas leak. Don’t flip light switches and don’t go hunting for it. Get everyone outside and call Spire from there. Their gas safety page spells out exactly what to do, and we can come out once the gas company says it’s safe.
If Spire leaves a red tag on an appliance, we’ve explained what a red tag means and how the gas gets turned back on on our furnace page.
Three Things You Can Check Before You Call
A few problems take 30 seconds to rule out. These are safe for anyone to look at:
- The breaker (electric heaters). If it’s tripped, flip it back once. If it trips again, leave it off and call us, because something inside is shorting.
- The knob on the gas control (gas heaters). It should point to ON, not PILOT, OFF or a vacation setting. Kids and storage boxes bump these more often than you’d think.
- The cold water valve on top. If the tank is leaking, turn that handle to the right until it stops. That keeps the tank from refilling while you wait for us.
If you smell gas at any point, skip all three and get out of the house.
A Water Heater Rebuilt Part by Part
Here’s a job Sam described himself, in a reply to a customer review. A customer’s electric water heater had quit, and the tank itself was still solid. So instead of replacing it, Sam rebuilt it. He put in both heating elements, both thermostats and a new relief valve.
That’s the kind of repair that makes sense on a good tank. Everything that wears out on an electric heater got replaced, and the customer kept a tank that had years left in it.
Speed matters too. One customer wrote that from the first phone call to a finished repair took less than 24 hours. That’s normal for us, because Sam answers his own phone and keeps parts on the truck.
How a Water Heater Repair in Oakville Call Goes
- You call (314) 600-2202. Sam wants to know what it’s doing, gas or electric, and roughly how old it is.
- He tells you if it can wait. Some problems are safe until morning. Leaks and gas smells aren’t.
- We test, not guess. We check power, gas, the controls and the parts with a meter.
- You hear what’s wrong in plain words, and the price, before we fix anything.
- We fix it with parts from the truck whenever we have them, so it’s usually one trip.
- We run it and watch it heat before we leave.
When a Repair Stops Making Sense
We’ll fix a water heater as long as it makes sense to fix. But a tank that’s leaking from the body, or an old tank that keeps needing parts, isn’t worth putting more money into. If yours is past about 10 to 12 years and the repair is a big one, Sam will tell you that plainly and let you decide.
Tankless units need repairs too. Error codes, lukewarm water and units that shut off mid-shower are usually scale buildup or a sensor. If you’re still deciding on tankless, read about the gas, vent and panel checks a tankless conversion needs before you buy.
Frequently Asked Questions
What Is the Most Common Problem Behind Water Heater Repair in Oakville?
For electric heaters it’s a burned-out element or a thermostat, which Sam can usually swap the same day if the tank is still in good shape. For gas heaters it tends to be the pilot, the little sensor that watches the flame, or a lint-clogged air screen at the bottom, and those rarely take more than one trip.
Should I Fix or Replace My Water Heater?
If the tank isn’t leaking and it’s under about 10 years old, we’d fix it almost every time. A leaking tank body, or an old heater that needs a big part like the gas control valve, is usually where we’d say put that money toward a new one, and Sam will say what he’d do if it were his own basement.
Is It Safe to Shower If My Water Heater Is Broken?
Sure, it’ll just be a cold one, since a broken heater doesn’t do anything to your tap water. The exceptions are a leaking tank, where you should shut the cold water valve on top and kill the gas or the breaker, and any gas smell, where everybody gets out of the house and you call Spire first.
What Happens If I Never Flush My Water Heater?
Sediment keeps piling up on the bottom of the tank, so you get popping noises, less hot water and a burner or element that has to work harder every year. Over time that crust can overheat the bottom of the tank and cut its life short, which is why we suggest flushing a younger tank about once a year.
Should I Flush a 15-Year-Old Water Heater?
Maybe not, and here’s why. On an old tank that’s never been flushed, the gunk can jam the drain valve open, and sometimes that buildup is the only thing plugging a pinhole leak, so give us a call first and we’ll tell you whether it’s worth the gamble on your tank.
Who Should I Call for Water Heater Repair, a Plumber or an HVAC Company?
Either one can do it, as long as the person who shows up knows both the gas side and the water side of the heater. Liberty does heating, cooling and plumbing, so the same person can test your gas valve, your heating elements and your water lines without you having to call a second company afterward.
