In Which Seasons Should You Ensure That Your Water Supply Is Turned Off? Regardless of the season, you should ensure that your main water supply is turned off before leaving for vacation. However, in winter, you should be more vigilant. During this season, the water inside water pipes may freeze.
With the start of summer and the end of school, many of you are thinking about summer vacation. Before you leave for some relaxation, you should turn off the water to your home to avoid common plumbing disasters.
Does shutting off the water affect the water heater? When you go on vacation, it's best to also turn off your water heater, as well as the main water supply. Turning off the source of the heat (gas, electric) while you're away will not damage your water heater.
No. Anytime you turn off water to house, always de-energize tank heaters. If water drained down for some reason, you don't want air in tank with energy source on. Can cause dangerous conditions or damage heater. Also, make sure to bleed any air from heater before turning energy back on.
Turning off the main water supply is generally safe and is often necessary for various situations, such as repairs or maintenance. Here are a few considerations: Purpose: If you're fixing a leak, replacing fixtures, or winterizing your home, it's advisable to turn off the main supply to prevent water damage.
Pipes can still burst in freezing temperatures even after you turn off your home's water. The pipes will still have water inside them, which means the water may freeze and potentially burst your pipes.
Immediately after you turn off the main water valve, turn on a tub or sink faucet to its highest level, for both hot and cold connections. This relieves the pressure in the plumbing lines, and also ensures a full shut-down. Continue to open faucets around the house to drain down the home.
If your main water supply is turned off for any reason, it's best to shut down the water heater as a precaution until the supply resumes.
After shutting off the main valve, ensure you drain the water from all the fixtures. In summer, the temperature of the water raises the pressure inside the pipes. If there is a crack, parts of your plumbing could burst. It is even more critical to drain hoses and faucets in the winter.
Relieve the pressure in the pipes by draining the water that's already in them. Turn on a sink located in the lowest level of your home, so water in the pipes from the floors above drain all the way down. Make sure to open both the hot and cold taps and run them until they empty completely.
Else, if you have a full water tank, and you need to turn off the water for an issue unrelated to your water heater, then it really doesn't matter if you turn the water heater on or off.
Shut Off the Water
This step isn't necessary for a short getaway, but if you will be gone a week or more it is a good practice to get into. It's best to turn off the water main but if you have appliances like an ice maker that need water regularly you can still turn off the water to your bathroom toilets and sinks.
If boilers didn't come with a host of sensors and controls, it might indeed damage your boiler if you turned it on with no water to heat up. Your combi boiler would be the worst affected, as the heat exchanger could suffer, but your cylinder and radiators would probably be fine.
If it is located inside your house, it will most likely be a gate or “wheel” valve that you'll simply turn clockwise to stop the flow of water. Another way to shut off the water is to go to the water meter box. Just be careful not to mess with the city shutoff side of the meter.
Unplug appliances and devices
Electronics like TVs, computers, and gaming consoles drain energy when plugged in, even if they're turned off or in sleep mode. Before you leave, unplug these electronics and appliances.
If the icemaker on your Refrigerator will not be used for some time, such as during a vacation or when the appliance is placed in storage, we recommend that you shut off the water supply to the Refrigerator and turn off the icemaker.
WSSC suggests running all COLD water taps for about five minutes or until the water runs clear. Begin with the lowest faucet in your home or business and then open the other faucets one at a time, moving from your lowest floor to your highest.
To prevent damage to your home, it is advisable to turn off the main shut-off valve before going on a vacation. You can find the main valve in the basement, crawlspaces, concrete slab, or the attic. You might also find the main shut-off valve in a utility box near your front sidewalk.
Overall, it's best that you take heed and drip your faucets when temperatures dip below freezing. A simple trickle of hot and/or cold water—both from faucets inside and outside the home—can prevent you from having to deal with a much larger issue (and bill!) in the long run.
Shutting Off Your Water Heater Can Cause Problems
If you have an older unit, you may have some difficulty turning it back on after being shut off for several days. The stress of rebooting the system of an older unit could lead to water heater repairs or a full replacement.
It's better to leave the hot water heater on all the time, rather than turning it on and off. This is a very common energy saving myth. But in fact, you really don't need to be heating your water all the time. Your immersion heater or boiler will heat up hot water which is stored in a tank.
It's important to shut off the power to your water heater before draining it, or you could potentially burn out the heating elements. If you have an electric water heater, shut the power off from your home's electrical panel.
Simply turn off the main water supply valve, which is typically located inside your home, right where the main pipe enters the house. With some homes, the valve is located on the exterior where the pipe connects to the water meter and enters the house.
You should open the faucets (turn them on) shortly after you turn off the main water to your house to drain the pipes, and if you're leaving the water off for an extended period, you should keep the faucets open while it's off. Opening the faucets drains the pipes once you turn the water off.
When you shut off a faucet, the water still has some force, which has to be absorbed, causing the pipe will flex. If the pipe is near wood, it will bang against the wood. You can stop this plumbing noise problem by installing water hammer arrestors on the offending water lines.
