Turning The Water Off At The Main Shutoff Valve

How to turn off your water heater – step by steps instructions

If your leak is somewhere in the main branch line, or if there is no fixture shut-off valve near the fixture you need to repair or replace, find the main shut-off valve for the home. This is usually found in a utility space near where the main water line enters the house, or on an outside wall near the water meter. This valve will always be located on the same side of the house as the water meter and it is usually a rather large valve.

This valve rarely gets closed, so it may be a little stiff to operate.

After shutting off the main shut-off valve, if you open the lowest faucet in your home and also the highest faucet in the home, it will allow water standing in the plumbing system to drain away. This means the water supply pipes will be empty of water, which can prevent water from spilling out when you begin your work on them.
