Should I turn off the pilot light on my water heater?
Turning off your water heater’s pilot light will save money on your energy bill since the water heater won’t keep the water warm while you’re away.
What keeps the pilot light lit on a water heater?
The tip of the thermocouple sits over the pilot flame, generating a voltage that keeps the gas valve open. If it senses that your water heater’s pilot light has gone out, the thermocouple will shift off the gas supply to the heater.
Does pilot light on water heater stay on all the time?
The burner on your water heater should not stay on all the time. The burner should only light when hot water is needed. However, your water heater’s pilot light should remain on at all times.
What happens to water heater when water is shut off?
When your water line is shut off, cold water stops flowing into your home entirely, and if your water heater has a tank, the tank will stop refilling with cold water. If your water is shut off for long periods of time and you use your hot water heavily, this can create the risk of serious damage.
Will gas leak if pilot light is off?
If the pilot light goes out on a storage or instantaneous hot water heater, space heater or a ducted heater, you will not have a gas leak. This is because all modern gas appliances with pilot lights have a fail-safe device that closes off the gas to the appliance in the case when the pilot may go out.
Should I turn off gas to water heater?
Whenever you’re going out away for an extended period of time, it’s always a good idea to turn off your gas water heater. Shutting off your gas water heater when you won’t be using it for a while saves on gas and helps prevent overheating problems that might arise when you aren’t there to take care of them.
Where is the gas shut off on a water heater?
The gas meter shut off is located right next to the gas meter that is found on the exterior of the house as shown below. The gas valve is on when it is parallel to the incoming gas line. When the valve is turned a quarter turn so that it is perpendicular, then the gas line is closed and the flow of gas is off.
Can I shut off water to water heater?
Locate the plumbing line, usually near or at the top of the water heater. Turn the valve off, and you will have successfully turned off the water supply.
How do you know if you have a bad thermocouple?
If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.
How much does it cost to replace a water heater thermocouple?
Thermocouple – $20 to $150 The thermocouple is an apparatus that senses whether the pilot light is lit and triggers the gas control valve. Repairs typically cost about $150 to have it done professionally, though a new thermocouple itself only costs about $20 on average.
Can you clean a thermocouple?
The best way to clean your thermocouple is to use either a piece of steel wool or the coarse side of a sponge to gently clean off any soot or other remnants. You can use a pencil eraser to clean between the threads of the screw that connects the thermocouple to the control valve of your system.
Will a pilot light stay lit with a bad thermocouple?
A thermocouple senses the heat of the pilot and allows gas to flow to the burner. A bad thermocouple will shut off gas to both the pilot and the burner so the pilot light won’t stay lit.
How do you tell if the pilot light is out on a water heater?
No flame where there should be a flame? These are signs the pilot light on your water heater is out. Fortunately, it’s a really easy fix. Signs your pilot light is out
- Your Water is Cold.
- Blinking Light or Error Message.
- You Can’t See the Flame.
What causes the pilot light to go out?
Sometimes a pilot light can go out as a result of some source of wind or air simply blowing it out. If this happens, there could be an issue with how your flue pipe is set up or how your system is venting.
