Important Basics to Know About Water Heater Repair
It’s crucial to call for water heater repair when a water heater is experiencing problems to prevent the issue from worsening and causing breakdowns that can leave the household without hot water. Therefore, homeowners should be aware of the signs that indicate water heater problems so they can call a plumber for water heater repair. This brief water heater guide will discuss signs indicating that repair is needed, common water heater issues, and when replacing the water heater may be necessary rather than repairing it.
Signs Water Heater Repair Is Needed
A water heater can send clear warning signals before it completely fails, and recognizing these indicators allows homeowners to call for repair before more severe issues occur. Common signs indicating water heater repair may be needed include:
- Insufficient hot water or no hot water
- Strange noises like rumbling, popping, or banging
- High utility bills
- The pilot light won't stay lit or frequently extinguishes
- Rusty-looking or discolored hot water from fixtures
- Strange-smelling or tasting hot water
- A visibly leaking water heater or water pooling around the water heater's base
If any of these warning signs are noticed, a plumber should be called to inspect the water heater and address the issue before the problem worsens and leads ot complete system failure.
Common Water Heater Issues
Many issues can occur with water heaters, but many signs of water heater troubles can stem from a handful of common problems. Water temperature-related issues can be caused by problems such as sediment buildup and a malfunctioning thermostat or heating element. A defective thermostat cannot accurately regulate water temperature, while a malfunctioning heating element in an electric water heater can disrupt the heating process.
Sediment accumulation in the tank can create an insulating barrier that reduces the unit's ability to heat water properly, causing inefficiency and forcing the unit to work harder than necessary, which in turn raises utility bills. Beyond temperature and efficiency issues, sediment buildup can cause additional signs, such as unusual sounds during operation and discolored water.
Pilot light problems that can plague a gas water heater can occur due to issues such as a faulty thermocouple that fails to detect the pilot flame properly, causing the gas valve to shut off as a safety measure. Similarly, a broken pilot assembly prevents proper ignition, affecting the pilot light’s ability to stay lit and can leave the home without hot water. Because signs that a water heater repair is needed can be caused by several different problems with varying solutions, it’s essential to have professionals inspect the water heater system to identify and address the underlying issue.
When Is Replacement Needed Rather Than Repair?
While repairs are crucial for fixing water heater issues, water heater replacement may be a more sensible and cost-effective option in certain situations. The unit’s age is an important factor when deciding whether to repair or replace a water heater. Traditional storage water heater models typically last about 8-12 years, so when a water heater is over a decade old and experiencing issues, replacement may make more sense than continuing to repair an old unit that has lost efficiency with age.
Frequent repair calls can also signal it's time to consider replacement instead of continuing to pay for repairs, as repair costs can add up over time, especially when repair costs exceed 50% of a new unit's price, making replacement more cost-effective. Another indicator that water heater replacement is needed is corrosion. The corrosion may be visible on the unit’s exterior, or signs of a corroded water heater may be noticed, such as discolored, rust-colored hot water and hot water with unusual metallic tastes or smells. Discolored water or strange tastes and smells from sediment buildup can often be resolved through draining and flushing. However, if it’s due to corrosion, the water heater will need to be replaced.
