Blog Common Water Heater Issues and Solutions from J&S Plumbing of the Carolinas Feb 20, 2025

Having a well-functioning water heater is essential for any household, especially during the colder months. However, like any appliance, water heaters can experience issues that disrupt their functionality. At J&S Plumbing of the Carolinas, we frequently encounter a variety of water heater problems that are common but certainly fixable. Here’s a guide to understanding and addressing some of these issues to ensure your water heater operates efficiently and effectively.

One common complaint we get from homeowners is inadequate hot water. If you find that your water heater is not providing enough hot water, there may be a few reasons behind this. A faulty thermostat is often the culprit, and adjusting or replacing it can resolve the issue. Another possibility is a sediment buildup in the tank, which reduces the efficiency of the heating element. Regular maintenance, including flushing the tank, can prevent this problem and ensure optimal performance.

Water temperature fluctuations can also be a frequent annoyance. Inconsistent water temperatures often indicate a problem with the temperature setting or a failing heating element. It's important to check that the thermostat is set to the correct temperature—usually around 120 to 140 degrees Fahrenheit. For electrical water heaters, issues with the power supply can also cause inconsistent heating, necessitating the examination of circuit breakers or wiring faults.

Some homeowners report noisy water heater operation. Unusual sounds, such as popping or rumbling, typically point to sediment accumulation at the bottom of the tank. As the water heats up, trapped water pockets in the sediment turn to steam and escape, causing noise. Performing regular flushing of the water heater can mitigate these sounds and prolong the life of the unit.

In addition to these issues, water heaters can sometimes develop leaks, which should never be ignored. Leaks can arise from several areas including valves, the tank itself, or the water connections. It’s crucial to inspect these areas to identify the source of the leak. If you discover a serious leak in the tank, it might be time to consider a replacement, as this can indicate corrosion or excessive wear.

If you're experiencing higher than usual energy bills, your water heater might be the cause. An inefficient water heater consumes more energy, often due to factors like a broken thermostat, increased sediment, or age. Upgrading to an energy-efficient model, like a tankless water heater, or simply servicing the existing system can help reduce energy costs substantially.

Routine maintenance is key to preventing many common water heater issues. At J&S Plumbing of the Carolinas, we recommend annual inspections and cleanings to keep your water heater in top shape. This not only helps avoid unexpected breakdowns but also extends the lifespan of your appliance.

When faced with water heater issues, it can be tempting to tackle the problem on your own. However, professional inspection and repair ensure that the problem is properly corrected without causing further damage.
