Common Water Heater Problems

Water heaters often show warning signs before they stop working completely.

Some of the most common issues include:
-Water not getting hot enough
-Hot water running out too quickly
-Water heater making popping or banging noises
-Rusty or discolored hot water
-Rotten egg or sulfur smell from hot water
-Water leaking around the heater
-Pressure relief valve dripping
-Low hot water pressure
-Fluctuating water temperature
-Burner or heating element problems
-Sudden increase in gas or electric bills

If you notice any of these symptoms, early diagnosis can often prevent more expensive repairs later.

Water Heater Making Noise

One of the most common service calls we receive in the Nixa and Springfield area is for noisy water heaters. Popping, rumbling, knocking, or crackling sounds are usually caused by sediment and calcium buildup inside the tank. Over time, minerals settle at the bottom of the water heater and harden. As the burner heats the tank, steam bubbles become trapped under the sediment layer, creating loud popping or banging noises.

This buildup can:
-Reduce heating efficiency Increase utility costs
-Overheat the bottom of the tank
-Shorten the lifespan of the water heater

Professional flushing and descaling can often restore quieter operation and improve performance.

Water Heater Flushing & Sediment Removal

Regular water heater flushing helps remove calcium, scale, slime, and sediment buildup that naturally accumulates over time. This is especially important in areas with hard water conditions. In many cases, excessive mineral buildup is directly related to untreated hard water. (Installing a water softener system helps reduce calcium and magnesium levels in the water supply, significantly slowing down scale formation inside the water heater and other plumbing fixtures)

Our water heater maintenance services include:
-Full tank flushing
-Sediment removal
-Heating element inspection
-Thermostat testing
-Water pressure checks

Routine maintenance can help improve efficiency, reduce noise, and extend the life of your system.

Rotten Egg Smell in Hot Water

If your hot water smells like sulfur or rotten eggs, the problem is often caused by a chemical reaction involving the anode rod inside the tank. In many cases, the original magnesium anode rod reacts with naturally occurring bacteria or minerals in the water supply. This can create an unpleasant sulfur smell in the hot water.

Depending on the condition of the system, solutions may include:
-Flushing and disinfecting the water heater
-Replacing the anode rod
-Installing an aluminum-zinc anode rod
-Adjusting temperature settings

This is a very common issue with both city water and well water systems.

Water Heater Leaking From the Bottom

A leaking water heater should never be ignored. Even a small leak can eventually cause flooring damage, mold, or structural issues.

Leaks may come from:
-Loose plumbing connections
-Drain valves
-Expansion tanks
-Temperature and pressure relief valves (T&P valves)
-Internal tank corrosion
-In some cases, a leaking relief valve may indicate excessive water pressure or a failed thermal expansion tank.

Our technicians inspect the full system to identify the actual source of the leak before recommending repairs or replacement.

Expansion Tank & Water Pressure Problems

Many homes in Missouri have thermal expansion tanks installed on the water heater system. These tanks help absorb pressure increases that happen when water expands during heating.

If the expansion tank loses its air charge or becomes waterlogged, it can lead to:
-Dripping relief valves
-Pressure spikes
-Pipe stress
-Premature water heater failure
-Plumbing leaks throughout the home

At VELLTOX Plumbing, we check:
-Expansion tank precharge pressure
-Overall house water pressure
-Pressure regulator operation
-Proper expansion tank sizing

If necessary, we recharge the expansion tank to match the home’s water pressure.

Temperature & Pressure Relief Valve Inspection

The temperature and pressure relief valve is one of the most important safety components on a water heater.

If the valve begins leaking, dripping, or failing to operate correctly, it may indicate:
-Excessive system pressure
-Overheating
-Expansion tank failure
-Valve wear or corrosion

We inspect and test relief valves for proper operation and verify that the discharge piping meets current plumbing safety standards.

Should You Repair or Replace Your Water Heater?

Not every water heater needs to be replaced. Many issues can be repaired if they are caught early.

However, replacement may be recommended if:
-The tank is leaking internally
-Severe corrosion is present
-The system is over 10–15 years old
-Repair costs are too high compared to replacement value
-The heater no longer meets your household hot water demands

We provide honest recommendations and help homeowners choose the most practical and cost-effective solution.
