There are many ways to test a hot water heater thermometer. Some people use a digital thermometer while others prefer using a mercury thermometer.

Here are two methods to test a hot water thermostatic valve:

Method 1 – Digital Thermometer

Digital thermometers are very accurate and easy to read. They also can be used to check other parts of the home as well.

To test a hot water thermo-stat, first disconnect the gas line and remove the cap from the top of the valve. Then, place the probe into the tank. Once the reading has stabilized, record the number.

Next, reconnect the gas line and reinsert the cap. You can now turn on the gas and see how the temperature rises. If it takes longer than 15 minutes to reach the desired temperature, then there’s probably a problem with the thermostat.

If the temperature stays constant or drops after 15 minutes, then there’s probably nothing wrong with the thermostat itself.

Method 2 – Mercury Thermometer

Mercury thermometers are inexpensive but not as accurate as digital thermometers. They’re also difficult to read because the liquid inside them is opaque.

To test a thermostat, simply insert the thermometer into the tank until it reaches the desired temperature. Record the reading.

Once the reading has been recorded, remove the thermometer and wait 30 seconds. Turn off the gas and remove the cap. Now, insert the thermometer again and record the temperature. Compare the readings.

If the temperatures are different, then there’s probably something wrong with the thermostatic valve.
