Save Water and Save Money- California Energy Commission State Law Change
On August 14, 2019, the California Energy Commission formulated a regulation with Resolution 19-0814-7 mandating that all spray sprinklers must include a pressure-regulating device, effective October 2020 (Irrigation Association). According to this restriction, the sprinklers that do not comply with the California Energy Commission’s new regulation, cannot be sold. This does not mean that the installed sprinklers need to be changed, but that sprinklers sold after October 2020 must be equipped with new pressure regulators. The pressure regulator is designed to save water and thus save money. According to Gachina Landscape Management, “Pressure regulated sprinklers are estimated to save more than 400 million gallons of water per day; enough savings to meet the water needs of the city of San Diego for 10 years.”
The average sprinkler head runs off of 55 psi and is equivalent to a 20 gallons per minute flow rate in a 15 head zone. With the pressure regulator installed, it reduces the psi to 30 which allows for a total reduction in water usage by 7.2 GPM.
The pressure regulator is located in the base of the sprinkler. This will not compromise the pop-up itself. It will, however, give you the ability to change the sprinkler head to fit your customer-desired needs. Even with reduced pressure, it will not affect the sprinklers’ overall distance or performance.
Does this give you a limited selection of sprinkler sizes? No, according to Imperial Sprinkler Supply’s Procurement Director, “There will be absolutely no change to the variety of products you can choose from.” We are dedicated to providing our customers with a wide range of products and solutions to meet every project need.
