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.
"There is no downside to turning off the water. It takes a little bit of time, and it can save thousands of dollars in potential water damage."
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.
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. Continuing to run your water heater when the tank isn't full could cause heat damage to the internal components.
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.
Your Home's Main Water Shut Off
Sometimes it can be found along a wall in your garage, or even under your kitchen sink. When turned off, it shuts down all water flowing into your home. As you can imagine, when a pipe bursts, knowing how to turn off that water flow becomes invaluable knowledge.
After all faucets are open, let the COLD WATER run for at least 30 minutes. During this time, also flush each toilet in your home 2 or 3 times.
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.
If you're away during warmer months, placing the water heater in vacation mode is unnecessary, and the heater can just be powered off. This goes for both gas and electric water heaters. For gas, twist the thermostat dial to the OFF position. For electric models, turn off the water heater at the circuit breaker.
If you have an electric water heater, it is recommended that you shut off the power and the cold water supply to the water heater if you are going away for any length of time. You will save electricity and limit any damage in case the tank leaks. Upon your return, do a visual inspection of the water heater.
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.
Even if you're only leaving for a few days, it's a great idea to shut off the water supply to your house. It's quick and easy to do and it lets you have one less worry while you're away. You don't need to turn off the water at every valve under sinks, behind the toilet, or near the water heater.
The gate shutoff valve is round and shaped like a wheel. To close, turn the shut-off valve clockwise until it's firmly closed. The ball valve has a lever handle, and to close it, you turn the handle one-quarter clockwise until it's tightly closed.
If your hot water tank is empty and is not going to be refilled right away, you should turn off your water heater. This will prevent the tank from taking any damage from excessive heat buildup while it's empty. There are a couple of common reasons your hot water tank would be empty.
As an estimate, the water in your tank should stay hot for a day or two. The larger the tank, the greater the heat loss will be, and it depends on the quality of your tank as well as the form of insulation you have.
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.
The main valve is always placed along the perimeter of the foundation, so it'll be near the wall, not the center of the household. It's also usually installed at or near ground level, so you can skip checking the upstairs and attic. In most cases, the valve is connected to a copper pipe beside the water heater.
If you are leaving the house empty for more than a few days, it should be safe to leave your heating on, however, even if you do turn off the water. It can be useful to have your central heating ticking over on a low temperature while you're not there with the help of a smart thermostat.
Discolored water and trapped air are common occurrences after a water main break or other water system maintenance work. Discolored water is caused by sediment and mineral deposits in the pipes that can be stirred up when the water is turned off and then back on following work on WSSC Water's water system.
Fixing a Stuck Water Shut Off Valve

One should normally open all faucets then turn on the main. This will allow any trapped air to be purged from the system and eliminate any 'banging'.
