Testing Water Temperature in Your Home

By
Home Inspector with National Property Inspections

Protecting young children and others from burning themselves in hot water is important, and you may have more control than you think. Many water heaters have a manual temperature setting. Water temperatures over 120 degrees F can cause scalding. That's why a water temperature assessment is an important part of a general home inspection.

A water temperature assessment has two parts. The inspector uses a thermometer, usually held under the water in the shower, while operating at least one other water fixture, to determine any significant changes in water temperature. First, the temperature in the shower is adjusted to about 105 degrees F. Then the toilet and sink are operated. If temperatures in the shower shift more than five degrees, it's noted in the inspection report. This same test is also used help assess and report on water volume in the home. Visible changes to the volume of water available when all three fixtures are operating are noted.

To test the general temperature of hot water in the home, the inspector will turn the hot water all the way on and use the thermometer again. Both of these water tests provide you information about the current condition and safety of your home. If temperatures are at dangerous levels, the hot water setting can be changed to protect people in your home.
