WPLLD Installation with Stage II Vapor Recovery Systems
Systems that have a Stage II Vapor Recovery Device installed in the pressurized piping require special installation
procedures. Because the WPLLD must be installed downstream from these devices, a monitored containment sump or
mechanical leak detector is required. The WPLLD will not detect leaks upstream from the valve (i.e. between the valve
and the Submersible Pump).
Also, there must not be a check valve installed between the WPLLD valve and the Submersible Pump for WPLLD to
function properly.
Refer to Figure 4-17 for WPLLD installation in Red Jacket Standard or Red Jacket Quantum without Spikecheck pumps
with a Healy Mini-Jet system. Follow the applicable guidelines in “SwiftCheck Valve Installation” on page 4-1.
IMPORTANT! Ensure that the Healy pump is wired according to the manufacturer’s instructions and utilizes isolation
relays.
