Proper Installation of Valves and Leak Detectors for Pressurized Underground Piping

According to Florida administrative code rule 62-762.501(3)(a)6., all pressurized small diameter integral piping in contact with soil must have line leak detectors installed within one year of January 11, 2017. These detectors should be downstream from the anti-siphon or solenoid valve and tested annually. PEI/RP200-13 outlines that line leak detectors should also be installed on the discharge side of each remote pump where piping is below grade. Proper installation is crucial for compliance and safety. Images demonstrate correct and incorrect setups.

1. Valves and LLDs Proper Location of Manual & Anti-siphon Devices in Conjunction with Leak Detectors For ASTs with Underground Pressurized Piping Rule 62-762.501(3)(a)6. states: All pressurized small diameter integral piping installed prior to January 11, 2017, that is in contact with the soil must be installed with line leak detectors (LLDs) meeting the requirements of paragraph 62-762.601(4)(b), F.A.C., within one year of January 11, 2017. The line leak detectors must be tested annually at intervals not exceeding 12 months in accordance with paragraph 62-762.601(1)(b), F.A.C., and be installed in accordance with Section 7 of PEI/RP200-13, 2013 Edition. Line leak detectors must be located downstream from the anti-siphon or solenoid valve. Line leak detectors are not required for piping that is not in contact with the soil. PEI/RP200-13 Section 7.2.2 states: 7.2.2 Remote Pumping Systems. Install a line leak detector on the discharge side of each remote pump (see Figure 7-4) where any portion of the piping is below grade. The line leak detector must be installed downstream of any solenoid valve installed in the piping.
