Frequently Asked Questions About Water Shut Off Valve
Where is the water shut-off valve located in a typical Melbourne home?
The main water shut-off valve is typically located near the property boundary where the water supply enters from the street, commonly in a meter box at the front of the property, under the house, or in a basement. Check your water meter box first, as this is the most common location in Melbourne. If you cannot find it, Emergency Plumber Melbourne can locate it for you during a service call.
How do I turn off my water shut-off valve in an emergency?
Locate the valve handle and turn it clockwise (to the right) until it stops. The valve is fully closed when the handle is perpendicular to the pipe. To restore water flow, turn the handle counterclockwise (to the left). If the valve is stuck or difficult to turn, do not force it—call Emergency Plumber Melbourne immediately for assistance.
How often should my water shut-off valve be inspected?
We recommend having your water shut-off valve inspected annually as part of a seasonal plumbing checkup. Regular inspection helps identify corrosion, leaks, or mechanical issues before they become emergencies. If your valve is over 10 years old or difficult to operate, consider having it replaced by Emergency Plumber Melbourne to ensure reliability during emergencies.
