Water Temperature Fluctuating? It Might Be a Water Heater Repair Issue

Experiencing inconsistent water temperatures in your home can be inconvenient, uncomfortable, and even dangerous. Whether it’s a sudden burst of scalding hot water or an unexpected rush of cold water mid-shower, these fluctuations can point to a potential issue with your water heater. Read on as our experts at Roberts Plumbing Hydro Jet & Rooter discuss the possible causes of water temperature fluctuation and how professional water heater repair in Simi Valley, CA can be the answer.

Sediment Buildup in the Tank

Over time, minerals and debris can accumulate at the bottom of the water heater tank, causing a layer of insulation between the heat source and the water. This can result in inconsistent heating and ultimately lead to hot or cold spots within your household’s water supply.

To address this issue, it’s important to flush out the tank regularly to remove any built-up sediment. This can be done by attaching a hose to the drain valve on the tank and flushing out any debris until the water runs clear. It’s recommended to do this at least once a year to prevent further buildup and maintain efficient heating. If you’re not comfortable doing this yourself, you can entrust the task to a reliable provider of water heater services—like Roberts Plumbing Hydro Jet & Rooter.

Failing Heating Elements

Most electric water heaters use one or two heating elements to warm the water. If one of these elements becomes damaged or stops working, the system will struggle to provide consistent hot water. In some cases, you might get hot water only at certain times of the day. In others, the water might go from hot to cold within minutes.

A technician can test each element and replace any that are no longer functioning. This type of repair is generally quick and can restore your hot water supply to normal levels. If left unchecked, a failed heating element can place extra strain on the remaining component. That could eventually lead to a complete breakdown.

Thermostat Malfunctions

The thermostat in your storage type or tankless water heater regulates the water temperature. If it becomes faulty, the unit may overheat the water or fail to heat it at all. A malfunctioning thermostat can cause changes in temperature without warning. 

Inconsistent readings from a bad thermostat can make it hard to know what to expect when you turn on the tap. Replacing or recalibrating the thermostat is usually the best solution. A licensed plumber can identify if this is the issue and make the proper adjustments or replacements.

Worn-Out Dip Tube

The dip tube is a part inside the tank that directs incoming cold water to the bottom where it gets heated. If this tube becomes cracked or broken, cold water can mix directly with the hot water at the top of the tank. This causes a noticeable drop in temperature, especially when demand is high.

The dip tube is not easily visible, so a plumber would need to inspect the unit to confirm the issue. Replacing it is a straightforward repair and can immediately resolve temperature inconsistencies. Although it’s a small part, the dip tube is essential in keeping your hot water supply steady.

Aging Water Heater

If your water heater is over 10 years old, frequent temperature changes may be a sign that the entire system is nearing the end of its life. As internal parts wear out, the heater may no longer work as efficiently as it once did. Repairs might help in the short term, but ongoing issues could mean it’s time to consider a hot water heater replacement.

Older models also often lack the efficiency of newer systems, which can affect both water temperature and energy costs. A plumber can help you weigh the cost of repairs against the benefits of upgrading. In some cases, a new water heater installation may be the most cost-effective option.
