BLOG Understanding Water Heater Issues: Insights from SOS Plumbing Professionals May 31, 2025

Water heaters are an essential component of every household, providing the much-needed hot water for various daily activities. Yet, like any mechanical device, they are not immune to problems. To ensure that your water heater remains in optimal condition, it's crucial to recognize the signs of potential issues. In this guide, SOS Plumbing professionals share their insights into common water heater problems and how you can address them.

One of the most frequent water heater issues is lack of hot water. This problem could stem from a variety of sources, including a faulty thermostat, a broken heating element, or even sediment buildup within the tank. Regular maintenance checks can help prevent such problems. SOS Plumbing recommends flushing your water heater tank at least once a year to remove sediment, ensuring that the heating elements function efficiently.

Another issue that homeowners often face is inconsistent water temperature. If you notice fluctuating temperatures, it might be due to a malfunctioning thermostat or a failing heating element. In electric water heaters, this could particularly be the result of a single heating element breaking down in a dual-element system. To fix this, it might be necessary to replace the damaged element or, in some cases, recalibrate or replace the thermostat. Contacting a professional from SOS Plumbing ensures these replacements and adjustments are performed with expertise.

Water leakage is a major concern that should be addressed promptly to prevent water damage and inefficient performance. Leaks may arise from faulty pipes, a leaking tank, or malfunctioning pressure relief valves. It's important to identify the source of the leak. An experienced plumber from SOS Plumbing can inspect the entire system to determine the exact issue, ensuring that appropriate repairs or replacements are carried out without delay.

Strange noises coming from your water heater are often indicative of underlying problems. Rumbling, popping, or hissing sounds typically suggest mineral build-up or a considerable amount of sediment at the bottom of the tank. Over time, these deposits can lead to less efficient heating and potentially damage your water heater. Regular cleaning and maintenance can help prevent noisy operations and extend the lifespan of your water heater.

For those experiencing a drop in water pressure, the issue might be tied to scaling within the plumbing system or the water heater itself. Scale, which results from the accumulation of minerals like calcium and magnesium, can significantly impact water flow. Addressing this involves periodic descaling to ensure smooth and consistent water pressure. A professional from SOS Plumbing can assist with this process, providing necessary solutions tailored to your water heater's specific needs.

Routine inspection and maintenance are the keys to prolonging the life of your water heater and preventing unwelcome surprises. Scheduling annual checkups with SOS Plumbing can help identify potential issues before they escalate, saving you time and money in the long run.
