How do I turn off my water? Where do I find my home's master water valve?

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.
