6 Steps on How to Shut Off Water to Water Heater
How to Remove Pressure Relief Valve on Water Heater

When a water heater is functioning correctly, most people don’t pay it any mind. However, one critical component of a water heater is the pressure relief valve. It is designed to open if the pressure inside the heater becomes too high, usually due to a malfunction within the appliance. A faulty valve can be dangerous, but fortunately, it’s easy to remove and replace. If you are experiencing water heater issues, the relief valve may need to be replaced or cleaned. Removal of the valve is the first step to resolving the issue.

Before you begin, turn off the gas to the water heater or disconnect the water heater from the circuit breaker that supplies it with power. This will prevent any gas or electricity from reaching the water heater while you are working on it. Turn on a hot water tap somewhere in the house to relieve any pressure inside the tank. Next, attach a bucket or hose to the end of the discharge pipe coming from the relief valve and place the other end of the hose in a location that can handle water flow.

Once everything is set, you can start the removal process. First, place a wrench around the top of the pressure relief valve. Be sure to have a firm grip on it. Then, slowly begin turning it counterclockwise. There may be some resistance at first, but with continued turning, the valve will eventually loosen. Once it’s loose, continue turning until it is completely out of the heater. Inspect the valve for any damage or buildup, such as calcium deposits, which may be restricting its movement. If any buildup is present, clean it off with a wire brush or vinegar.

Identifying the Pressure Relief Valve

The pressure relief valve is a critical safety device that prevents your water heater from exploding due to excessive pressure buildup. It is typically located on the top or side of the water heater tank.

1 Quick Way To Test A Thermocouple On A Water Heater

6 Steps on How to Shut Off Water to Water Heater
Thermocouple On A Water Heater

Thermocouple on a water heater is a safety device that shuts off the gas supply to the burner if the pilot light goes out. This prevents gas from leaking into the home and creating a dangerous situation. Thermocouples can fail over time, so it is necessary to know how to test them to ensure that they are working properly. There are two methods that can be used to test a thermocouple on a water heater.

The first method is the “multimeter method”. This method requires a multimeter, which is a device that can measure voltage and resistance. To test a thermocouple with a multimeter, set the multimeter to the millivolt scale. Then, touch the positive lead of the multimeter to the terminal on the thermocouple that is connected to the pilot light. Touch the negative lead of the multimeter to the terminal on the thermocouple that is connected to the gas valve. If the thermocouple is working properly, the multimeter will read a voltage of around 25 millivolts.

The second method for testing a thermocouple on a water heater is the “ice cube method”. This method is simpler than the multimeter method, but it is not as accurate. To test a thermocouple with the ice cube method, simply place an ice cube on the thermocouple. If the thermocouple is working properly, the ice cube will melt within a few minutes. If the ice cube does not melt, the thermocouple may be faulty and should be replaced.

Visual Inspection

To begin your visual inspection, locate the water heater and isolate it from its power source by turning off the gas supply valve or disconnecting the electrical power. Once the water heater is isolated, proceed with the following steps:

1. Inspect the Thermocouple Assembly

Carefully examine the thermocouple assembly, which is typically located near the burner or pilot light. Look for any signs of damage or deterioration, such as:

Signs of Damage
  • Cracks or fractures in the thermocouple body
    		•
  • Corrosion or rust on the thermocouple tip
    		•
  • Bent or deformed thermocouple leads
    		•
  • Loose or disconnected connections
    		•

    If you observe any signs of damage, it is recommended to replace the entire thermocouple assembly.

    2. Inspect the Thermocouple Leads

    Check the thermocouple leads that connect the thermocouple assembly to the gas control valve. Ensure that the leads are securely connected and free of any damage or corrosion. Loose or damaged leads can result in unreliable thermocouple readings.

    3. Inspect the Gas Control Valve

    Locate the gas control valve and inspect its exterior for any signs of damage or corrosion. If you notice any abnormalities, such as cracks, leaks, or rust, it may indicate a problem with the valve and require professional repair.

    Continuity Test

    A continuity test is a simple electrical test that can be used to check if a thermocouple is working properly. To perform a continuity test, you will need a multimeter. Set the multimeter to the ohms setting and then touch the probes to the two terminals of the thermocouple. If the multimeter reads zero ohms, then the thermocouple is working properly. If the multimeter reads infinity ohms, then the thermocouple is not working properly and needs to be replaced.

    Here are the steps on how to perform a continuity test on a thermocouple:

    1. Set the multimeter to the ohms setting.

    2. Touch the probes to the two terminals of the thermocouple.

    3. If the multimeter reads zero ohms, then the thermocouple is working properly.

    4. If the multimeter reads infinity ohms, then the thermocouple is not working properly.

    Other ways to check a thermocouple for continuity:

    If you want to perform a continuity test on a thermocouple without using a multimeter, you can use a simple battery and lightbulb. Connect the positive terminal of the battery to one terminal of the thermocouple and the negative terminal of the battery to the other terminal of the thermocouple. If the lightbulb lights up, then the thermocouple is working properly.

    Hot Water Test

    The hot water test is the most effective and quick method to test a water heater thermocouple. For this test, you’ll need a multimeter set to the millivolt (mV) setting.

    1. Turn on the Hot Water Tap

    Start by turning on a hot water faucet at the furthest point from your water heater. Allow the water to run until it’s hot to the touch.

    2. Measure the Voltage

    Using the multimeter, touch the positive probe to the thermocouple’s terminal and the negative probe to the water heater’s ground wire. Record the voltage reading.

    3. Check the Voltage Output

    Compare the voltage output to the specifications provided by the water heater manufacturer. Typically, a working thermocouple will produce a voltage between 15-30 mV when the water is hot. If the voltage output falls below this range, the thermocouple may need to be replaced.

    Output Voltage Thermocouple Status
    15-30 mV Working properly
    Below 15 mV Needs replacement

    If you observe any voltage reading, it indicates that the thermocouple is working. However, a low voltage output may require further troubleshooting.

    Ice Bath Test

    The ice bath test is a simple and effective way to test the accuracy of a thermocouple. To perform the test, you will need the following items:

    • A thermocouple
    • A bucket of ice water
    • A thermometer

    First, fill the bucket with ice water and stir it until the ice is evenly distributed. Then, insert the thermocouple into the ice water and wait for the temperature reading to stabilize. Once the temperature reading has stabilized, compare it to the reading on the thermometer. The two readings should be within 1 degree Fahrenheit of each other.

    If the thermocouple reading is not within 1 degree Fahrenheit of the thermometer reading, then the thermocouple may be inaccurate. In this case, you should replace the thermocouple with a new one.

    Here are some additional tips for performing the ice bath test:

    • Make sure that the thermocouple is fully immersed in the ice water.
    • Stir the ice water occasionally to keep the ice evenly distributed.
    • Wait for the temperature reading to stabilize before comparing it to the thermometer reading.
    • If the thermocouple reading is not within 1 degree Fahrenheit of the thermometer reading, then the thermocouple may be inaccurate.

      Accuracy Table

      Error Action
      Less than 1 degree Acceptable
      Between 1 and 2 degrees Acceptable but monitor
      Greater than 2 degrees Unacceptable, replace

      Millivolt Output Test

      This test measures the electrical output of the thermocouple, which should be in the millivolt range. Connect a millivoltmeter to the terminals on the thermocouple. Turn on the water heater and set the temperature to the highest setting. Wait a few minutes for the thermocouple to reach a stable temperature. Read the millivoltmeter and compare it to the manufacturer’s specifications. If the output is below the specified range, the thermocouple may be faulty and needs to be replaced.

      Here are some additional tips for performing the millivolt output test:

      • Make sure the thermocouple is clean and free of any debris.
      • Connect the millivoltmeter to the thermocouple terminals securely.
      • Set the millivoltmeter to the correct range before taking a reading.
      • Wait a few minutes for the thermocouple to reach a stable temperature before reading the millivoltmeter.
      • Compare the millivoltmeter reading to the manufacturer’s specifications to determine if the thermocouple is functioning properly.
      Symptom Possible Cause
      No millivolt output – Faulty thermocouple
      – Loose or damaged wiring
      Low millivolt output – Thermocouple is dirty or corroded
      – Flame is not strong enough
      – Airflow is restricted
      High millivolt output – Thermocouple is too close to the flame
      – Pilot light is burning too high

      Comparison with a Known-Good Thermocouple

      This method is the most accurate way to test a thermocouple on a water heater. However, it requires you to have access to a known-good thermocouple.

      To test a thermocouple using this method, follow these steps:

      1. Disconnect the wires from the thermocouple that you want to test.
      2. Connect the wires from the known-good thermocouple to the water heater.
      3. Turn on the water heater and let it run for a few minutes.
      4. Use a multimeter to measure the voltage between the terminals of the known-good thermocouple.
      5. Compare the voltage reading to the voltage specification for the water heater.
      6. If the voltage reading is within the specification, the thermocouple is good.
      7. If the voltage reading is not within the specification, the thermocouple is bad and needs to be replaced.

      Here is a table summarizing the steps involved in this method:

      Step Description
      1 Disconnect the wires from the thermocouple that you want to test.
      2 Connect the wires from the known-good thermocouple to the water heater.
      3 Turn on the water heater and let it run for a few minutes.
      4 Use a multimeter to measure the voltage between the terminals of the known-good thermocouple.
      5 Compare the voltage reading to the voltage specification for the water heater.
      6 If the voltage reading is within the specification, the thermocouple is good.
      7 If the voltage reading is not within the specification, the thermocouple is bad and needs to be replaced.

      Resistance Measurement

      To test the resistance of a thermocouple, you will need a multimeter. Set the multimeter to the ohms setting and touch the probes to the terminals of the thermocouple. The resistance should be within the manufacturer’s specifications. If the resistance is too high or too low, the thermocouple may be damaged and should be replaced.

      Typically, a multimeter is turned to the setting that displays resistance in ohms (Ω). When touching the probes to the thermocouple terminals, the reading should register between 5 and 50 Ω. If the reading registers 0 Ω or an endless reading of “OL”, then the thermocouple is likely shorted or broken, respectively.

      Below is a table that provides general resistance values with corresponding temperature ranges for type K and type T thermocouples:

      Temperature (F) Type K (Ω) Type T (Ω)
      32 0.0 0.0
      212 6.152 5.314
      482 16.93 14.66
      752 29.73 25.92
      1022 44.34 38.84
      1292 60.50 53.20
      1562 78.02 68.85
      1832 96.69 85.63
      2102 116.5 103.4

      Temperature Probe Simulation

      To simulate a high-temperature signal, disconnect the thermocouple from the water heater. Then, connect a variable resistor to the thermocouple wires, as shown in the table.

      Increase the resistance until the multimeter reads the expected voltage for the simulated temperature. The table provides the resistance values for different temperatures.

      Temperature (F) Resistance (kΩ)
      100 100
      150 150
      200 200

      If the water heater still does not heat up, the problem may be with the flame sensor, gas valve, or igniter. You may need to call a qualified technician to diagnose and repair the issue.
