What Is a Stopcock?
A stopcock is the main valve used to control the flow of water into a property. It allows the water supply to be turned on or off when carrying out repairs or dealing with plumbing emergencies.
A properly functioning stopcock is essential for:
Isolating water during emergencies
Preventing excessive water damage
Carrying out plumbing repairs
Managing water supply issues
Maintaining plumbing systems safely
If your stopcock fails when you need it most, it can significantly increase the risk of water damage and disruption.
