Water Heater Woes: Identifying and Fixing Common Problems Dec 18, 2025

Dealing with a faulty water heater can be a frustrating experience. However, understanding some of the common problems can turn a potentially cold shower into a manageable repair. At MVP Plumbing, we understand the concerns homeowners have when faced with water heater issues, and we're here to guide you through some of the most frequent problems and how they can be resolved.

Water heaters are elemental in providing comfort and convenience in our daily lives. But like any other appliance, they encounter issues that can disrupt this service. One of the most prevalent problems homeowners report is the lack of hot water. This could be due to various reasons, including a faulty thermostat, a broken heating element, or a pilot light that's gone out. In electric water heaters, a common culprit is a tripped circuit breaker. Before assuming the worst, check these components, as they can often be switched back on or replaced.

Another frequent issue is water that is too hot. If you find your water heater is producing overly scalding water, it typically points to a thermostat set too high. The general recommendation is to set your thermostat to around 120 degrees Fahrenheit. This temperature should provide adequate hot water while also preventing the risk of burns, especially in households with children.

Discolored or rusty water is a concern that often indicates corrosion inside your water heater tank or in the pipes. An aging anode rod, which is intended to protect the tank from corrosion, may also be the cause. Replacing a worn-out anode rod can extend the life of your water heater and improve water quality.

Homeowners frequently encounter issues with noisy water heaters as well. Sounds like popping, banging, or rumbling often signal the buildup of sediment in the tank. Over time, minerals from hard water accumulate at the bottom of the tank, compromising its efficiency and potentially leading to damage. Routine flushing of the tank can help eliminate these sediments, maintaining the heater’s functionality and efficiency.

Another prevalent problem is water leakage from the heater. Leaks can arise for various reasons, such as pressure buildup due to overheating or a faulty temperature and pressure relief valve. In some cases, the leak might be due to a more serious issue, like a crack in the tank. Since leaks can lead to water damage and mold, it's crucial to address them promptly. If you aren't comfortable performing these checks yourself, a professional from MVP Plumbing can inspect the water heater and help diagnose the issue.

In summary, staying ahead of water heater issues can save you time, money, and headaches. By regularly inspecting your water heater and performing simple maintenance tasks like checking the thermostat, flushing the tank, and replacing parts when necessary, you can keep your unit running smoothly for years.
