Water Heater Repair & Installation in Nixa, MO

When the hot water quits, everything in the house slows down. Showers, dishes and laundry all wait on one appliance, and a water heater rarely picks a convenient day to fail. The good news is that many water heater problems are repairs, not replacements, once you know what you are looking at.

Short answer

No hot water from a gas water heater usually points to the pilot, thermocouple or gas valve. On an electric unit it is usually a tripped breaker, a failed heating element or a bad thermostat. Hot water that runs out fast often means sediment or a broken dip tube. Water leaking from the bottom of the tank almost always means the tank has failed and needs replacing. We diagnose first and give you the price before any work starts.

Repair or Replace: What Decides It

Three questions settle most water heater decisions in Nixa homes.

• Is the tank itself leaking? A leak from the tank body cannot be repaired. Leaks at fittings, valves and connections usually can.
• How old is it? The manufacture date is printed on the label or coded into the serial number. An older unit that needs a major part is often a better candidate for replacement than repair.
• How often has it needed work? One repair on a sound unit is normal. A string of repairs is a sign the whole unit is wearing out.

If replacement makes sense, a new water heater is also a chance to get the size right, which ends the problem of running out of hot water for good.

Symptoms and What Usually Causes Them

Hard Water and Sediment in the Nixa Area

Much of the water in southwest Missouri is hard, carrying dissolved minerals from the limestone underground. When that water heats up, some of those minerals settle out and collect on the bottom of the tank.

That sediment layer does real damage over time. It insulates the water from the burner on a gas unit, so the heater runs longer to do the same job, and it can bury the lower element on an electric unit. It is also the source of the rumbling and popping many homeowners hear.

Regular maintenance keeps it in check. Flushing the tank clears loose sediment, and checking the anode rod catches corrosion before it reaches the tank wall. Tankless water heaters handle hard water differently: they need periodic descaling to keep minerals from building up inside the heat exchanger.

Tank or Tankless?

A traditional tank water heater costs less to buy and install, and it stores a ready supply of hot water. Once that supply is used, you wait for the tank to recover.

A tankless unit heats water on demand, so it does not run out the same way, and it takes up far less space. It usually costs more up front, and it may need a larger gas line, new venting or more electrical capacity depending on the model. For homes that already have one, our tankless water heater repair service covers descaling, error codes and flow problems.

Safety: The Relief Valve and the Temperature Setting

Every tank water heater has a temperature and pressure relief valve. Its job is to open if the tank gets dangerously hot or pressurized. A valve that drips now and then is telling you something is wrong. A valve that has been capped or plugged is a serious hazard and should never be left that way.

Federal energy and safety guidance generally recommends setting a water heater around 120 degrees. That setting lowers the risk of scalding and cuts standby energy loss. Gas water heaters also need proper venting, so a working carbon monoxide alarm near the utility area is a smart addition.

A leaking tank can release a lot of water quickly. The EPA’s guide to mold and moisture recommends drying water-damaged areas within 24 to 48 hours, so do not wait on a puddle next to the heater.

What a Water Heater Installation Includes

1. Sizing. The new unit is matched to your household’s hot water use, not just the size of the old one.
2. Removal. The old unit is drained and disconnected.
3. Connections. New water connections, gas or electrical connections and venting are made to code.
4. Safety checks. The relief valve and its discharge line are installed correctly, and an expansion tank is added where the plumbing system requires one.
5. Fill and test. The tank is filled, air is purged from the lines, and the unit is fired up and checked for leaks before we leave.

Water Heaters and the Rest of Your Plumbing System

A water heater is tied into the whole plumbing system, so plumbing issues in one place often show up in the other.

• Water pressure. High pressure strains the tank and makes the relief valve drip. A thermal expansion tank or a pressure-reducing valve is often the real fix.
• Leaks nearby. Supply connections, the drain valve at the bottom of the tank and the relief valve line are common leak points. A small drip there can still cause water damage to a floor or wall over time.
• A clogged drain valve. In homes that have never flushed their water heater, the drain valve can clog with sediment and refuse to close properly after flushing.
• Older pipes. In older homes in Nixa, corroded supply lines at the top of the tank are worth replacing when the water heater is replaced.

If the leak turns out to be somewhere other than the water heater, our leak repair service tracks it down.

When to Replace Your Water Heater Instead of Repairing It

It is usually time to replace your water heater when the tank is leaking, when an aging unit needs a major part, or when repairs keep coming back. If the tank is leaking now, call us right away and shut off the water supply to the heater.

A replacement is also a chance to upgrade. A higher efficiency tank, a tankless water heater or a unit sized properly for your household can bring energy bills down, because an older unit that is scaled up with sediment works harder than it should. During the visit, a technician can do an inspection of the water supply connections, the venting and the relief valve so the new unit starts out right.

Routine maintenance protects the new water heater once it is in. Flushing the tank and checking the anode rod on a schedule helps it last. Because we are an HVAC and plumbing company, that maintenance can happen on the same visit as a heating and cooling tune-up. Contact us today at (417) 356-4048 to set it up.

Water Heater Warning Signs Worth a Call

• Rust-colored hot water or rust around the fittings, which can mean the tank is corroding from the inside.
• Strange noises such as popping or rumbling, usually from sediment built up in the bottom of the tank.
• Inconsistent temperatures, or a hot water supply that runs out sooner than it used to.
• Water around the base, or a relief valve line that drips.

Catching these signs early can extend the life of your water heater and head off costly repairs. A tankless system has its own warnings, such as error codes or water that swings between hot and cold. Our water heater service covers tank and tankless units along with the water lines connected to them, as part of our plumbing services in Nixa. We are fully licensed, offer same-day service on most calls and handle emergency plumbing when a tank fails. If you notice any of these signs, give us a call.

Water Heater FAQs

Why is my water heater leaking?

Leaks at the top usually come from fittings or connections and can often be repaired. A leak from the bottom of the tank usually means the tank has failed.

What size water heater do I need?

It depends on how much hot water your household uses at its busiest time of day. A tank’s first-hour rating, printed on its label, is a better guide than tank size alone.

Why does my hot water smell like rotten eggs?

That smell usually comes from a reaction between bacteria in the water and the anode rod. Replacing the anode rod and flushing the tank often solves it.

Is a tankless water heater worth it?

For many households, yes, especially where hot water runs out often or space is tight. The installation cost and your gas or electrical setup decide whether it pays off in your home.
