Why Is Your Water The Wrong Temperature?

Is your water cold when it's supposed to be hot or hot when it's supposed to be cold? Here are some problems that could be the cause.

Faulty Water Heater Thermostat

One of the main causes of incorrect water temperature is a faulty water heater thermostat. The thermostat in your water heater is responsible for maintaining the set temperature. However, if it malfunctions, it can lead to temperature inconsistencies. 

For example, if the thermostat is not accurately measuring the water temperature, it may fail to signal the heating element to turn on or off at the right time. As a result, you might end up with water that is either too hot or too cold. In such cases, you should have a professional plumber inspect your water heater and replace the thermostat if necessary.

Sediment Buildup in the Water Heater

Over time, mineral sediment can accumulate at the bottom of your water heater tank. This sediment buildup can make it harder to get properly heated water. As the sediment settles, it can insulate the heat source from the water, reducing its overall temperature or making it take longer to heat up. 

If that happens, you may notice that your hot water is not as hot as it used to be. To fix this problem, you'll usually need to have a plumber flush out your water heater to remove the sediment.

Crossed Hot and Cold Water Lines

Sometimes, the issue with water temperature is in the plumbing system itself. Improperly connected hot and cold water lines can lead to incorrect temperatures.

If the hot and cold water lines are switched, it can lead to water that has the opposite temperature of what you expect. This problem is most common after plumbing renovations when pipes can get accidentally swapped. It can also appear in old houses where the last owner just got used to using the faucets backward or didn't realize something like a toilet getting hot water.

Malfunctioning Mixing Valve

Certain plumbing fixtures, such as showers or faucets, utilize mixing valves to control the blend of hot and cold water. If the mixing valve malfunctions or becomes damaged, it can disrupt the proper mixture of hot and cold water, resulting in inconsistent water temperatures. 

You might experience sudden bursts of scalding hot water or icy cold water when you least expect it. Repairing or replacing the faulty mixing valve will ensure that the correct temperature blend is restored and maintained.
