The five sizes available for LADWP water sub meters are:
5/8″x3/4″, 1″x3/4″ intermediate, 1″x1″ regular, 11/2″, and 2″.
California Utility Services will get you the right size meter for your residence or commercial property. The water sub meter is read in hundred cubic feet. Each one unit represents 748 gallons of water. Your tier water usage and sewer service charge is based on hundred cubic feet units.
The service water meter and the water sub meter can be used for leak detection and conservation. For leak detection when you have all the water shut off at the property. Go to your service meter at the street and see if the diamond or star is moving? If it is then you have water coming onto your property without your knowledge.
Next you need to isolate water usage from house and irrigation. If you can turn off the house water line and the service meter is still moving then your leak is on the irrigation side. Look for wet areas, broken pipes or sprinkler heads. If the irrigation is shut off and the house water on and the service meter still spins then the leak is in the house. Look for toilets still running, dripping water faucets, water line from fridge, etc…
Conservation using water meters is achieved by monitoring and recording your usage around the same time LADWP reads your meters. Incorrect bills happen and it’s up to you to find the errors. Learn how to read your bill.
