Locating the Main Water Shutoff Valve

Knowing the location of your main shut off valve is crucial in case of plumbing emergencies like leaks or burst pipes. This valve allows you to cut off the mains water supply to your entire house.

There are a few common locations to check when trying to locate your mains water shut off valve:

  • Near the water metre - Many homes have the shutoff valve close to the water metre outside or in the garage. Look for a large stop tap coming off the meter.
  • Under the kitchen sink - Determine where your shut off valve is installed, possibly under the kitchen sink or another sink. Check under sinks and look for an inside stop valve behind access panels.
  • In an underground utility box - For underground shutoff valves, you can look for a meter box at ground level somewhere in your yard. The valve linked to your property will be inside.

When locating your valve, look for a large shutoff valve for your water heater to understand how turn off water, coming directly off your home’s main water line. It is helpful to attach a reminder tag to your main water valve so it is easily identifiable in an emergency.

Always learn how turn off water using your water shutoff valves slowly to prevent damage to your water supply pipes. It is also wise to know how to routinely check that your home’s main shutoff can turn water off in case it needs to be used during a plumbing emergency.

Identifying Different Types of Shutoff Valves

There are several common types of stop valves located in residential plumbing systems that allow you to shut off water supply:

Ball Valves

Ball valves, also known for their ability to regulate your plumbing system, are named for the ball-shaped mechanism inside that valves can stop or allow water flow when turned. They can be identified by the ball valve handle and are typically found under sinks, behind toilets, or alongside water heaters.

Gate Valves

Gate valves raise and lower a round “gate” to start and stop water flow. They are easy to identify by their wheel-shaped handle. Gate valves are most commonly found on the main lines entering a home as valve your property can depend on.

Globe Valves

Globe valves, a type of isolation valve, have a round opening and use a disc to stop water flow. They can be easily identified by their round disc-shaped handle. Globe valves are typical for managing plumbing gas, hot and cold water pipes, showers, tubs, and sinks.

Regular Maintenance for Prevention

Being proactive and knowing how to turn off your water system is key to preventing water emergencies and damage in your Jannali home. We recommend taking the following preventative measures:

Check Flexi Hoses

Inspect the condition of flexi hoses connecting sinks, toilets, washing machines and other appliances every 6 months. Ensure they are not cracked or bulging, as this indicates internal wear and imminent failure.

Test Valves

Every 3 months, test that your main shutoff valve located in your home fully stops the water supply your home requires. Also check your inside stop valve and appliance valves to confirm they operate properly and completely halt water supply.

Insulate Pipes

Water pipes exposed to the cold are more vulnerable, especially those that transport water into your household relies on. Insulate exterior and unheated interior pipework to minimise bursting risk during cold snaps.

Monitor Usage

Track water usage on bills to notice irregular spikes that may indicate silent leaks. Annual usage over 500,000L likely signals problems requiring further inspection.

Staying informed on your plumbing system’s status allows quicker response if issues arise. Contact Jannali Plumbing on 1300 349 338 for professional assistance maintaining and repairing your home’s water supply network.
