Okla. Admin. Code § 165:26-2-52
Current through Vol. 42, No. 4, November 1, 2024
Where tanks are at an elevation that produces a gravity head on the dispensing device, the tank outlet must be equipped with an anti-siphon device such as a solenoid valve, positioned adjacent to and downstream from the emergency valve, installed and adjusted so that liquid cannot flow by gravity from the tank in case of piping or hose failure when the dispenser is not in use.
