Water Heater Repair Services
Is your hot water temperamental? If your water heater isn’t working properly, call the plumbing experts at Dauenhauer. Our licensed plumbers will diagnose the issue quickly and provide the right solution.
We address many common repair needs, including:
- No hot water: If your hot water isn’t working altogether, it could be due to a failed heating element, pilot light issues, or electrical problems. We will identify the root cause and restore reliable hot water to your home.
- Inconsistent water temperature: If your water temperature fluctuates between hot and cold, there could be thermostat issues, sediment buildup, or a failing internal component.
- Strange noises: Odd noises, such as rumbling, popping, or banging, can signal sediment buildup at the bottom of your water heater, which reduces efficiency and can lead to long-term damage.
- Leaking tank: If there’s water pooling around your unit, there may be loose connections or your tank is failing. We will determine the problem and recommend a solution.
- Discolored water: Rusty or cloudy water can sometimes mean there’s corrosion inside your water tank or issues with the anode rod. These both require immediate attention.
Water Heater Installation & Replacement
Traditional tank water heaters typically have a lifespan of 8-12 years. Water heaters may begin to need more frequent repairs as they age. If your water heater is getting old and requiring costly repairs, you may consider getting a replacement water heater.
Upgrading your water heater to a modern unit can improve efficiency, provide consistent hot water, and reduce the risk of breakdowns.
When Replacement Makes Sense
- Water heater is nearing the end of its expected lifespan
- It needs increasingly frequent and costly repairs
- Energy bills are increasing due to inefficiency
- You have safety concerns
- Your current unit is undersized for your household’s needs
Benefits of Energy-Efficient Upgrades
You can reduce long-term operating costs by upgrading your water heater to an energy-efficient system. Modern water heaters are designed to heat water using less energy and offer reliable performance.
Additional benefits include:
- Lower energy bills
- Improved heating efficiency
- More consistent hot water supply
- Longer system lifespan
- Reduced energy consumption
Types of Water Heaters We Service
We service both tank and tankless water heaters in Louisville, Lexington, Shelbyville, and Elizabethtown.
Tank Water Heaters
These traditional hot water storage systems are common in Central Kentucky homes. They offer a lower upfront cost but take up more room in the home due to their design. The system stores a limited amount of water, meaning you can potentially run out of hot water depending on demand.
Tankless Water Heaters
Tankless water heaters provide hot water by heating it on demand instead of storing it in a tank. Their space-saving design makes them optimal for smaller homes with limited space. They are more energy-efficient than traditional tank water heaters and can supply unlimited hot water.
Signs You Need Water Heater Service

- Water not heating properly: When your water heater isn’t heating water properly or is providing inconsistent temperatures, it needs to be serviced. We will pinpoint the issue and make swift repairs.
- Sudden loss of hot water: If you don’t have hot water anymore, your system needs repair or replacement. We’ll diagnose the cause of no hot water and make an informed recommendation.

- Water heater older than 10 years: If your water heater is aging and not performing reliably anymore, you might consider an energy-efficient upgrade.

Water Heater FAQs
How many years does a hot water heater typically last?
8–12 years is the industry average for a standard atmospheric-vent gas or electric tank water heater (Lowe’s, Consumer Reports, Bradford White and A.O. Smith all agree on this range). Real life: units with soft water, annual flushing, and anode rod replacement every 3–5 years routinely hit 15–20 years. Units in hard water with no maintenance often die at 7–8. Signs you’re at the end: rusty water from only the hot tap, rumbling/popping sounds during heating, visible rust on the tank jacket, water pooling under the unit. Once a tank leaks through the steel shell, it cannot be repaired — only replaced.
How often should I flush my water heater and replace the anode rod?
Flush the tank annually — drain 2–3 gallons out through the bottom spigot until the water runs clear. This takes 15 minutes and clears the sediment layer that destroys the bottom burner/element and causes popping sounds. Replace the anode rod when it’s consumed to under 1/2″ diameter — typically every 3–5 years in normal water and every 2–3 years in soft/softened water (ironically, softened water eats anodes faster). Bradford White and Rheem manufacturers’ warranty literature explicitly states tank warranties cover defects, not neglect — a leak caused by a depleted anode voids the warranty.
Should I repair or replace my water heater?
The practical rule of thumb: if the unit is under 8 years old and the repair costs less than 50% of a replacement, repair it. Good repair candidates: thermocouple or gas valve on gas units; heating element or thermostat on electric; leaking T&P relief valve; anode rod replacement. Always replace when: the tank itself leaks (not a fitting — the actual tank shell); the unit is 10+ years old and needs a major repair; the unit is undersized for household demand (runs out of hot water regularly); or you’re already planning a bathroom or kitchen remodel that would benefit from a tankless or heat-pump upgrade.
What size water heater do I need?
The DOE uses “first-hour rating” (FHR) for tanks, not just gallons — it’s the gallons of hot water the unit can deliver in a peak hour. Sizing by household: 1–2 people — 30–40 gallon tank (FHR 50–60); 3–4 people — 40–50 gallon tank (FHR 60–70); 5+ people or homes with soaker tubs — 75–80 gallon tank or a tankless with at least 9 GPM. For tankless sizing, add the GPM of every fixture likely to run simultaneously: standard shower 1.8–2.5 gpm, kitchen faucet 1.5 gpm, dishwasher 1.3 gpm, laundry 1.7 gpm.
