2) Don't forget to tape plastic bag over disconnected gas connections to keep from getting dirty.
Dirt in the gas line, or on the threads can cause gas control valve to malfunction.

12 year old water heater is getting near the end.
Some tanks last 20 years, but that's the exception.
To find exact age of your brand water heater:

Leaking TP valve:
1) Lift TP lever and gently lower back into position to see if that stops leak.
Occasionally something gets stuck in the valve.
2) Sometimes water heater temperature gets turned up because heater is not producing as much hot water as before, and higher temps cause TP to release pressure because of overheating.
Dial temperature down to 120 degrees.

3) If steps above don't fix problem, replace TP valve >> TP valves have 125 or 150 degrees rating >>> older tank shouldn't be running above 125 because higher temps cause more pressure on tank, so thermostat should be lower than 125 degrees TP rating.
Buy replacement TP at any hardware store + a roll of teflon tape to seal pipe threads.
Turn gas control to pilot ... this will keep pilot lit but burner will not fire.
Let water cool, and then drain some water out of tank.
If TP valve is on side of tank, then open drain on side of tank and drain water until it is lower than valve level. Open bathtub spigot to let air into line.

Be careful around water that is higher than 120 degrees F >> you can get burned quickly >> apply cold water to any burn.
Use pipe wrench and unscrew TP valve counterclock-wise.
Install new TP and put teflon tape on threads.
Re-fill tank completely and open tub valve on hot side until water is running >> then turn gas control back to original position.
Do not fire up any water heater before tank is completely full of water or this could damage tank.

Hi,

Here is a tip that I wrote to help people understand how to adjust the temperature on their electric hot water heater.

Electric Hot Water Heater Temperature Adjustment
heatman101

The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If flame goes out it shuts gas off to the pilot jet. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced

you don't adjust hot water temp from the taps...

you can only adjust from the water heater.

what water heater do you have?

Does the gas flame fully heat up the coupler
if not then clean out the gas jet nozzle
if yes then replace the thermo couple

Look and see if your pilots flame is touching the themocoupling ,if it isnt then cleane your pilot orfice.If that dosnt work replace thethermocoupler.I would also check the draw. Hold alit match or a cigerett up to the draft diverter (the air space between your heater and the vent. If it dosent draw the smoke up the vent it meanes your vent is stoped up or you need to raise it.

Try this, turn the black gas ****, on top of the control box, to the Pilot position. Set the temp. control on the front of the box to the desired temp. Then, hold a match or whatever else you use to light it, next to the end of the pilot, then, while holding the match to the pilot, press the reset button on top. When the pilot lights, continue to hold the reset button down for about 1 minute. Then, after a minute, turn the gas **** to the ON position, then it should remain on.
