Consequences of Failing to Shut the Water Off When Going on Vacation

Before you go on a vacation, shutting off the water is always a must. You might never enjoy going on a vacation again if you come home and see your house has flooded with water.

When you forget to turn off your water while on vacation, the damage it could cause may ruin things at your home. Supply line leaks, water heaters dripping, frozen pipes, and appliance damage are all possible consequences if you fail to turn it off while you're away.

You would lose a great deal amount of money if water leaks cause damage. Things will need to be dried out, cleaned, and replaced as needed, and the electrical system will have to be rewired. 

It is usually a smart decision to turn off the water when you leave for a long time, especially when the weather in your area is unpredictable. The emotional stress of witnessing priceless items, precious memories, and family treasures drowning in water is an awful experience that no family ever wants to encounter. 

When Is The Best Time To Turn Off The Heater?

It isn't always necessary to turn the heater off when shutting off the water. Even if you forgot to turn off the heater when you shut the water off, there's nothing to worry about. This is true as long as you have a smart thermostat and a central heater set to a low setting,

However, it's best to think of the worst-case scenario in case you forget to turn off the heating and shut off the water while you're away. The water heater contains a tank that stores water, so it keeps the water there as long as you don't need it. If the water level in the tank decreases for any reason, it is best to switch the water heater off.

The best time to turn the heater off is only when your water will be off for a long time, and if you have a tank or hybrid water heater. It's okay to leave your water heater running during brief shutoffs until the water flows again.

Why Shutting Off Water Doesn't Affect the Air Conditioner?

Understanding how an air conditioner functions is a great thing. Ever wondered whether an air conditioner could function without water? How does an air conditioning system cool the air?

Water isn't usually necessary to operate AC units, so they aren't affected when water at home is shut off. Instead, the freezing temperature induces water droplets to form. Air filtration, evaporation, compression, condensation, and air release are the processes an AC uses to regulate air circulation.

Advice to Take When Away From Your Home

It's beneficial to have acquaintances in your neighborhood. You can invite a friend or a family you can trust to visit your house while you're away for a few days. This will help you to prevent any problems with your home's water supply.

  • To prevent water freezing and breaking pipes in the winter, drain water from the pipes.
  • Examine the supply lines to the appliances, and fix any broken ones.
  • Inspect your drainage system.
  • Look for a buildup of leaves and debris in the drains.

Steps For Shutting Off Water At Home

You'll need to shut off the supply of water in your home at some point. You might need to do this to prepare for a long trip or a scheduled plumbing repair. There are also unexpected circumstances where there is often not that much time to react.

1. Find the location of the valve

Depending on the condition of your house and the weather where you live, the main water shut-off valve may be in a variety of areas. Either a gate valve, which resembles a circular spigot, or a ball valve, which has a handle in the shape of a lever, will serve as the knob.

The valve might be located inside the home, outside on a wall, or outdoors buried close to the road.

If it's within the house, search the basement, laundry room, and utility areas. It will typically be located lower down on the main floor.

The shut-off valve could be mounted on an outside wall outside the house in some warmer climes. Start looking for it by the outdoor faucet.

Check outdoors where it is buried close to the road. At or near your water meter outside, there is typically a water supply shut-off valve that the city can use to switch on or off your water. It will most likely be close to the street, beneath an access panel that is buried in the ground.

2. Turn the water off

Give a gate valve a few clockwise twists until you can no longer turn it to shut off the water supply. Turn the lever 90 degrees clockwise to adjust the ball valves.

3. Run the taps

Drain the water already flowing in the pipes to release the pressure. Your home's lowest level sink should be turned on to ensure that water in the pipes from the floors above flows all the way down. Open the hot and cold taps and let them run until they are empty.

4. Turn the water back on

Turn the valve clockwise and turn on the water once the repairs are completed. Turn on a faucet and wait a few moments for the water to get to it to make sure all of it is back to normal.

Why Is It Important To Run Water After Shutting It Off?

You should run the water first before turning off the water. This will help ensure a complete shut-down by relieving pressure in the plumbing pipes. If there is any old water in your plumbing or service line that may have greater amounts of metals, like lead, running the water can get rid of it.
