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 holiday again if you come home and see your house has flooded with water.

When Is The Best Time To Turn Off The Heater?

Turning the heater off when shutting off the water isn't always necessary.

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 if 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, keeping 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.

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.

Steps For Shutting Off Water At Home

You'll need to shut off the water supply 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 little 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.

A gate valve resembling a circular spigot or a ball valve with a handle shaped like a lever will serve as the knob.

The valve might be located inside the home, 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 climates. 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 the city can use to switch on or off your water. It will most likely be near the street, beneath an access panel 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 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.
