Who Do You Call For Water Heater Problems?

When you encounter water heater problems, the professional you’d typically call is a licensed plumber. They have the expertise to diagnose and fix issues with your water heater.

Imagine it’s a cold winter morning, and you’re looking forward to a hot shower, only to find that your water heater isn’t working. It’s in these moments that you realize the importance of having a reliable plumber who can promptly address and resolve your water heater issues.

In essence, plumbers are trained to handle a variety of water heater problems, from minor issues like adjusting the thermostat to major ones like replacing the entire unit. They can work on different types of water heaters, including tankless, electric, and gas models. 

Understanding Common Water Heater Problems

Before we delve into who to call for help, let’s briefly explore common water heater problems you might encounter:

No Hot Water

One of the most prevalent and frustrating water heater issues is a lack of hot water. You turn on the tap, expecting a soothing stream of warmth, but all you get is cold water. This problem can be caused by various factors, including:

Faulty Heating Element

In electric water heaters, the heating element is responsible for heating the water. If it malfunctions or burns out, it can result in no hot water. Replacing the faulty heating element is often the solution.

Thermostat Problems

The thermostat in your water heater regulates the temperature of the water. If it’s not functioning correctly, it may fail to heat the water to the desired temperature. Adjusting or replacing the thermostat can resolve this issue.

Power Supply Problems

In some cases, the absence of hot water can be attributed to power supply problems. This may include issues with the circuit breaker, fuse, or electrical connections. Checking and rectifying these electrical issues may restore hot water.


Water heater leaks can vary in severity, ranging from minor drips to major flooding. Leaks are a distressing problem as they can lead to water damage, increased energy bills, and even mold growth. The potential sources of leaks in a water heater are:

Tank Issues

Over time, the tank in your water heater can deteriorate, leading to small cracks or holes. These imperfections can result in water seepage. In cases of tank corrosion or damage, replacing the water heater might be the best course of action. A tankless water heater can be installed in a closet and avoid potential water heater issues caused by tank deterioration.

Pressure Relief Valve

Water heaters have pressure relief valves that release excess pressure to prevent tank rupture. If the valve malfunctions or is improperly installed, it may leak water. Replacing a faulty pressure relief valve can resolve this issue.

Pipe Connections

Leakage can also occur at the connections between the water heater and the pipes. These connections may loosen over time, causing water to escape. Tightening the connections or using thread seal tape can fix the problem.

By understanding these common water heater problems, you can better diagnose the issue before seeking professional assistance, potentially saving time and money.

Strange Noises

Water heaters aren’t supposed to be noisy appliances, so when you start hearing unusual sounds emanating from your unit, it’s a clear sign that something is amiss. These sounds can take the form of popping, hissing, or rumbling, and they often indicate problems associated with sediment buildup or issues with the heating element.

Sediment Buildup

Over time, sediment, minerals, and other debris can accumulate at the bottom of your water heater tank. When the heating element heats the water, it can cause these deposits to harden and create a layer at the bottom. The popping or rumbling sounds you hear are the result of this trapped sediment being agitated by the heating process. 

Heating Element Issues

Another cause of strange noises is a malfunctioning or deteriorating heating element or plastic inserts in the water heater. The hissing or sizzling sounds can occur when the heating element overheats or experiences electrical problems, or when the plastic inserts become warped or damaged. In such cases, it’s advisable to contact an electrician or a water heater specialist to inspect and, if necessary, replace the heating element or plastic inserts.

Water Discoloration

When you turn on your hot water tap and notice discolored water flowing out, it’s certainly cause for concern. Discolored hot water typically indicates issues with the water heater, such as corrosion or sediment inside the tank.


If the hot water appears rusty or brown, it’s a sign of corrosion inside the tank. Corrosion can occur due to a variety of reasons, including a reaction between the metal tank and the minerals in the water.


Water that appears cloudy or has floating particles may signal sediment buildup inside the tank. This not only causes water discoloration but can also lead to a host of other issues. A plumber can flush the tank to remove the sediment and improve the water’s quality.

Fluctuating Temperature

Few things are more frustrating than stepping into a shower with water that can’t decide whether it wants to be hot or cold. Inconsistent water temperature can be attributed to several issues, including a faulty thermostat or heating element.

Thermostat Problems

If the thermostat in your water heater is malfunctioning, it may fail to regulate the water temperature accurately. This can lead to sudden changes in water temperature while you’re using hot water. An electrician or a water heater specialist can assess and adjust the thermostat as needed to ensure consistent temperature control.

Heating Element Issues

Faulty or deteriorating heating elements can also cause temperature fluctuations. The heating element may struggle to maintain the desired temperature, resulting in hot water becoming lukewarm or cold intermittently.

Who to Call for Water Heater Problems

The appropriate professional to call for water heater problems may depend on the severity of the issue and the type of water heater you have:


For common issues like leaks, no hot water, or water discoloration, a licensed plumber is often the first point of contact. They can diagnose the issue, perform repairs, or recommend a replacement if necessary.


If your water heater is electric and you’re facing electrical problems, such as tripped circuits or heating element issues, it’s best to contact a qualified electrician.

HVAC Technician

For gas water heaters, HVAC (Heating, Ventilation, and Air Conditioning) technicians are trained to handle gas-related problems. If you smell gas or suspect a gas leak, contact a professional immediately and ensure your safety by evacuating the premises.

Manufacturer’s Service Team

If your water heater is still under warranty, it’s advisable to contact the manufacturer’s service team. They can provide authorized technicians for repairs and replacements covered by the warranty.

Water Heater Specialist

Typically, water heaters can be repaired by licensed plumbers.

Your initial point of contact when you encounter water heater issues should be a licensed plumber. These professionals focus exclusively on water heaters and are equipped to handle a wide range of problems.
