5 Signs to Call a Plumber to Look at Your Water Heater

June 16, 2025

Your water heater is an essential component of your home, providing the hot water you rely on for daily activities such as showering, cleaning, and cooking. Like any appliance, water heaters can experience problems that may require professional attention. Left unchecked, minor issues can quickly escalate into significant damage, leading to water loss, property damage, or even safety hazards. Regular monitoring of your water heater’s performance is key to catching potential problems early. Knowing the signs that indicate your water heater needs a plumber's expertise can save you from unexpected breakdowns and costly repairs. In this post, we will explore five critical signs that suggest it's time to call a local plumber to look at your water heater.


1. Inconsistent Water Temperature

If you're finding that your water temperature fluctuates unpredictably, this is a common sign that your water heater may need expert attention. Inconsistent water temperatures can be caused by various issues, such as a failing heater element, mineral buildup, or malfunctioning thermostat. These problems can worsen over time, leading to reduced efficiency and higher energy bills. Calling a local plumber to assess the situation can help identify the underlying problem and determine whether a repair or replacement is necessary for long-term reliability.


2. Strange Noises from the Heater

Unusual noises coming from your water heater, such as popping, banging, or rumbling, are often a red flag. These sounds typically indicate sediment buildup within the tank, which can lead to decreased efficiency and tank deterioration. If left unaddressed, this buildup can cause overheating, increased pressure, and even cracks in the tank lining. A professional local plumber can flush the tank to remove the sediment, helping to extend the life of your water heater and restore its performance and safety.


3. Discolored or Smelly Water

If the water coming from your hot water tap appears rusty or has an unpleasant odor, it could indicate a problem with your heater. Mineral deposits or a corroded anode rod can cause these issues, leading to water contamination. These problems not only affect water quality but can also damage internal components of the heater over time, reducing efficiency. According to The Spruce, a properly maintained water heater can have a lifespan between 10 to 20 years. Regular inspections by a local plumber can prevent these issues and ensure your appliance remains in good condition throughout its expected life, ultimately saving you money and inconvenience.


4. Leaking or Pooling Water

Water leakage around your water heater is a significant sign that immediate attention is needed. Leaks can stem from various sources, including faulty pipe connections, a damaged pressure relief valve, or a compromised tank. Left unchecked, even small leaks can cause structural damage to floors, walls, and nearby belongings, potentially leading to mold growth and costly restoration work. Ignoring leaks not only risks water damage to your home but can also lead to an eventual breakdown of the unit if not addressed promptly by a skilled plumber. Early detection and timely repairs are key to avoiding major disruptions.


5. Reduced Hot Water Supply

A decrease in your hot water supply or a longer wait time for hot water might indicate an issue with your water heater's capacity or heating elements. This problem can occur from sediment build-up or when the heating elements wear out over time. In larger households, increased water demand may also strain the system, revealing the need for an upgraded or more energy-efficient model. Consulting with a local plumber can provide clarity and the necessary solutions, whether it be a repair or a recommendation to consider a more suitable unit for your household's needs.


Paying attention to these signs can help maintain your water heater in optimal condition and avoid disruptions to your daily routine. By recognizing inconsistent water temperatures, strange noises, discolored water, leaks, and reduced capacity, you can take proactive steps by calling a plumber to investigate and resolve the issues promptly. Keeping your water heater well-maintained will not only preserve its lifespan but also ensure the comfort and safety of your home.
