The water customer shall install and maintain, at his own expense, a gate valve and valve box on the customers side of the meter box. This can be a gate or other similar type valve. This is to facilitate shut-off for repairs of customer’s service lines or leaks, etc. Customers or repairmen cannot use the service valve inside the meter service box. Any damage to the system valve, including water loss, will be billed to the customer. Approved backflow devices are installed at each meter by the water system. These must not be tampered with. Report any leaks at the meter service box or anywhere on the water system to the Water District.
