Surprisingly, there’s another shut-off valve located within your street, and it’s responsible for controlling the water supply to your home. This street valve can be a useful backup in case you can’t locate the one within your home or if it’s not functioning correctly. Typically, you’ll find your street’s water valve near the boundary line of your property, often close to the pavement. It’s marked by a ground-level metal or plastic trap door. However, before attempting to operate this valve, it’s essential to contact your water company for guidance. They can either shut it off for you or provide instructions on how to do it yourself.
