The shutoff of the water supply to your home is generally required for repairs to the pipes or fixtures in your plumbing system at home. There are, at minimum, three places to stop the flow of water, and the choice of where to shut off the water will be based on the location where the leak is or whether maintenance or repair is required to take place. In general, you don’t need any tools to close off the water.

There are various places where the water supply to your home can be shut off, and how to select the appropriate one.

Turning the Water off at the Fixture or Appliance

If you notice that a faucet is drippy or a water heater is operating–or when a leak occurs in the refrigerator’s freezer, dishwasher, washing machine, or other appliance powered by water–the first and most effective option is to turn off the water directly to the device or fixture. If you shut off the water local to the source, the other institutions connected to your plumbing system at home will continue to work while you work to repair the leak.

However, The valves for the fixtures’ shutoff may differ in appearance and position. Generally, they’ll be close to the appliance or fixture.

For sink taps, search for shutoff valves beneath the sink. These valves are close to where the tubes for the water supply run up to the tailpieces of the faucet. A faucet that can supply hot water will come with two valves – one for hot water and another for cold water.

In the case of toilets, there will be one shutoff valve (a toilet only uses cold water), usually situated near the floor beneath the valve for the water supply at the side of the tank. This valve for supply usually is on the left-hand side at the bottom of the tank.

In the case of tubs and showers, check in the tub or shower to find the access panels. It could be located just across the wall from the shower or tub. If it’s not in the access panels, it could be beneath the floor in the basement, or an access panel for the ceiling is beneath the flooring. Shower bodies are made with built-in stopping devices (valves). They can be accessed when you remove the escutcheon plates. It’s dependent on if the contractor has purchased and installed a valve that has stops. This is a requirement in all high-rise buildings.

For dishwashers, the water supply tube that connects to the dishwasher is usually fitted with a valve to shut off the regulating fixture. In many instances, it’s also beneath the base of the kitchen sink cabinet. It could also be located near the suitable shutoff valves.

For water dispensers and ice makers in refrigerators, The small supply tube of copper or mesh connecting to the refrigerator generally comes with the saddle valve or fixture shutoff valve that may be shut off to shut off the water supply. In certain instances, the supply tube connecting to the refrigerator might relate to the water supply line under the sink, close to where the sink faucet’s supply tubes are located.

For washing machines that usually wash clothes, there’s a water supply valve that controls that hot water intake hose and a second one that holds that cold-water supply. They can be found in a utility sink when your laundry has one or inside a recessed water supply valve set on the wall close to that washing machine.

You’ll get the idea. Every appliance or fixture should have local shutoff valves.

However, if you cannot locate the shutoff valves in your area, don’t be concerned. You can turn off the water supply by shutting off the main valve for the water supply close to the water meters.

Turning the Water off at the Main Shutoff Valve

If the leak is inside the main branch line or if there’s no shutoff valve for the fixture near the fixture you wish to fix or replace, locate your primary shutoff valve for your home. It is typically found in a utility room close to where your primary line of water comes into the house or perhaps in an exterior wall close to the water meters. The valve will be situated on the exact side of the house where the water meters are, and it’s usually an oversized valve.

This valve is not often closed, so it could be difficult to use.

After closing the valve that shuts off your water supply when you turn on the lowest faucet inside your home (such as in the basement or a base-level faucet for outdoor use) and the highest faucet inside the house that will permit water within the plumbing system to be drained out, this means that the pipes for the water supply are empty of water. This will keep water from leaking when you start working on the lines.

Turning the Water off at the Water Heater

If your hot water pipe is in danger of leaking, or you must repair or replace a water heater, fix or change your water heater. There are shutoff valves that can be found close to your water heater.

A water heater is equipped with two valves to shut off. An inlet valve to cold water (often identified by the blue handle) will feed chilled water from the supply to the heater. This valve will close if you are required to replace or repair your water heater.

Pipes for hot water outlets come with a valve that can close off all hot water that leaves in the heater. It is possible to shut off this valve in case of an issue with a hot water pipe in the home since it controls all hot water within the house. The valve is usually identified by the red handle, which indicates that it is holding hot water. This easy color coding is essential since the cold water intake pipe and hot water outlet pipes are mostly near one another, and it is difficult to tell them apart. Both valves will cut off hot water from your entire home. Most contractors don’t install an outlet valve for both the hot and cold water outlet and the inlet of the heater since shutting off the cold water supply to the heater shuts the hot water out of the system.
