There are many circumstances in which the main water supply is turned off. When this happens, many homeowners wonder if it's safe to keep the water heater on of it should be shut down too. In most cases, it may not be necessary to turn off the water heater, but it also won't hurt, either.
If you need to turn your water off for any reason, it's always safer to turn your water heater off, too. While many water heaters will be fine for a while without a water supply, reduced water pressure or a low water level inside the tank could cause the heater's components to overheat and burn.
Some people prefer to turn the main water supply off when they go on vacation to reduce the risk of flooding. It's a pretty smart move, especially if you'll be away for an extended period. Ifyou're considering turning off your water heater while on vacation, you absolutely can—but it isn't necessary.
1 Answer. No it wont hurt the water heater.
While frequently turning on and off the water can cause too much pressure to be put on the water pipes, turning it off doesn't harm the system. Locate the mains water supply valve in your house, which may be in the basement or in a crawl space.
When the main water line is turned off, it cuts off the water supply to your entire house, including both hot and cold water. The reason why hot water stops flowing when the main water line is turned off is because the hot water system in most homes is connected to the cold water system.
As a water heater heats up, the water expands Unless you have an expansion tank, a small amount of water must be allowed to backup into the water mains. If the main water valve is turned off, there is no place for the water to expand into. So, do not turn off the water and leave the water heater on.
Therefore, a dirty thermocouple might be the reason why your water pilot keeps going out. A layer of dirt and grime can hinder the electric current from reaching the thermocouple. As a result, the gas supply will be cut off and the pilot light will go out.
Also, tank-type heaters burn energy (gas or electricity) day and night to maintain the water temperature, regardless of whether or not anyone's using hot water, a phenomenon known as standby heat loss.
In the average home, the water heater will run for about three hours each day. Total run time can range from one to two hours for new tankless water heaters to five or more hours for older tank style water heaters.
You don't always need to turn off the water heater if your house water is off; however, you should turn off the water heater if you'll be gone for extended periods or if you're making repairs to the water heater itself.
Yes it is safe to leave the water heater in pilot mode while flushing. You do not want the burner to fire while the tank is empty as this can damage the tank but the pilot will not cause a problem. Added: most gas valves with a standing pilot have the temp setting and “pilot” then off settings.
Remember to shut off the main water supply to your home any time you're planning to be away for more than 24 hours. Yes, that includes weekend breaks. It's the best way to avoid serious water damage in the event of a plumbing failure.
Typically, a water heater tank takes 30 to 40 minutes to heat up so if your water heater is still working, you can count on having more hot water come back in that amount of time as long as your system is still working adequately.
The pilot light on most water heaters can be found at the base of the unit just under the gas control valve. Open the access door or panel to the burner chamber and take a look inside. You should be able to see the pilot light tube. If there's a steady blue flame, your pilot light is operational.
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.
Although this is an area of concern for many people, the reality is that boilers are built so that the gas supply to the pilot light is shut off if the flame goes out. Whilst the cause of pilot light failure needs to be investigated, extinguished pilot lights aren't going to cause a gas leak.
Your Gas Has Been Shut Off
Your pilot light relies on your natural gas to stay aflame, so if your gas is shut off, your pilot light will go out. Simply turn your gas back on and either relight your pilot light yourself or call a professional.
The pilot light, however, is an actual old-fashioned flame inside your furnace. This flame is supplied by your gas line and should always be lit.
That's important because gas is always being supplied to the pilot to keep the flame lit. But if the pilot flame goes out, then the gas would still be released. After a while, the gas could collect in your home and become a health hazard.
For gas water heaters, the gas valve controls the temperature. The valve assembly features a dial which you can use to adjust the temperature. If the water temperature fluctuates but the pilot light is on, the gas valve assembly is probably at fault. This repair will need to be done by a qualified technician.
If your hot water heater doesn't have a vacation setting, simply manually adjust your temperature to resemble Vacation Mode by lowering the temperature to 50 degrees Fahrenheit, or the lowest setting your thermostat allows. You may also choose to turn your hot water heater off completely.
How Long Can You Turn Off Water to a Toilet? Like turning off your toilet's water for a night, it's safe to do so for a week. While you can keep your toilet water off for as long as you'd like, we wouldn't recommend it unless you have a problem with your toilet's plumbing system.
Unplug Appliances and Electronics
Save money on your energy bill and avoid the risk of an electric fire while you're gone by unplugging any electronics not associated with home security, lighting or your refrigerator. There's no need to leave your printer or bedroom TV plugged in when no one's around to use it.
