Your home's master water valve is called the "stop and drain valve." This is the valve used to turn off water to your house and drain your indoor water pipes. Every property is required to have a working stop and drain valve and is the ONLY valve you may use to shut off your water.
Customers are not authorized to turn off their water at the meter. Not only is that a punishable offense but it can cause extensive damage and serious injury. Meter valves may ONLY be turned by DWP personnel.
In addition, water can not be turned off to avoid paying the service charge. Water must be on at all times for customer access, the safety of our system, and in case of emergency (such as fires). If you think you need your water shut off at the meter for a leak or other emergency, please call Customer Service at (909) 866-5050.

The stop and drain valve is the customer's water shut-off valve, or water master valve, located between the water meter box and your house. Every property is required to be equipped with a working stop and drain valve.
This valve should be used to turn off your water and drain indoor water pipes. During the winter, using this valve is the best way to help prevent your water pipes from freezing and breaking. Go to the Winterization page for more information.
NEVER TURN OFF YOUR WATER BY USING THE VALVE INSIDE THE METER BOX. Not only is that a punishable offense, but turning this valve can cause extensive (and expensive) damage to the water system and/or cause serious injury due to water system pressure. Plus, it does not drain your indoor plumbing and therefore does not protect your water pipes from freezing and breaking.
