Veeder-Root Line Leak A#ation Guide 40 <br />Selecting a Line Leak Detector <br />This guide helps you to properly configure Veeder-Root's line leak equipment for underground pressurized piping systems. <br />Note: Since PLLD and WPLLD do not perform leak tests on the pump in all applications, appropriate containment/leak <br />detection must be provided when selecting either of these systems. VLLD systems must always be installed in a mon- <br />itored containment sump. <br />Veeder-Root offers four types of line leak systems, each uniquely suited to a particular type of application. <br />• PLLD Pressurized Line Leak Detection <br />• VVPLLD Wireless Pressurized Line Leak Detection <br />• VLLD Volumetric Line Leak Detection <br />• HVLLD High -Capacity Volumetric Line Leak Detection <br />PLLD and WPLLD eliminate the need to break the product line for installation or service. In addition, WPLLD installs without <br />running new wires. PLLD and WPLLD are the cost-effective choice for most retrofit and new piping installations. <br />Veeder-Root's line leak detection systems have been evaluated by a third party in accordance with EPA evaluation procedures. <br />Please refer to the test reports in Veeder-Root manual numbers 576013-308 and 576013-866 for the results of these evalua- <br />tions. <br />Major Features of Each Veeder-Root Line Leak Detector <br />Feature <br />LINE LEAK DETECTION <br />PLLD <br />WPILLD <br />VLLD <br />r <br />3 GPH TESTING <br />PRECISION TESTING <br />POSITIVE SHUTDOWN <br />YES <br />OPTIONAL <br />YES <br />YES <br />OPTIONAL <br />YES <br />YES <br />YES <br />YES <br />YES <br />YES <br />YES <br />3RD PARTY CERTIFIED <br />YES <br />YES <br />YES <br />YES <br />INSTALLATION REQUIREMENTS <br />3 -INCH DISCHARGE PUMPS WHEN PRECISION TESTING IS REQUIRED <br />REQUIRES TLS CONSOLE <br />YES <br />YES <br />YES <br />YES <br />INSTALLS WITHOUT BREAKING PIPING <br />YES <br />YES <br />NO <br />NO <br />INSTALLS WITHOUT NEW SUMP <br />YES <br />YES <br />YES <br />YESI <br />INSTALLS WITHOUT NEW WIRES <br />NO <br />YES <br />NO <br />NO <br />(Requires 42 -inch diameter sump minimum <br />Ideal Veeder-Root Line Leak Detector for Various Piping Systems <br />• EXISTING FIBERGLASS OR STEEL PIPING <br />WPLLD <br />• NO AVAILABLE INTRINSICALLY --SAFE CONDUIT <br />• NEW FIBERGLASS, STEEL, OR FLEXIBLE PIPING <br />PLLD <br />CONDUIT TO PUMP AREA EXISTS, IS EASILY INSTALLED, OR DIRECT BURIAL CABLE CAN BE USED <br />• 2 -INCH DISCHARGE PUMPS <br />VLLD <br />SUMP AND CONDUIT EXISTS <br />3 -INCH DISCHARGE PUMPS WHEN PRECISION TESTING IS REQUIRED <br />• HIGH THROUGH -PUT <br />HVLLD <br />• SUMP AND CONDUIT EXISTS <br />
