G Appurtenances and Accessories Flanged and Gusseted Fiberglass Nozzles (optional) Flanged and conically gusseted FRP nozzles are available in 2" 4; 6" and 0" diameters. The flange face matches the ANSI 150# face pattern. Mating flanges must be flat 4.-1 ® Fiberglass Fill Tube (optional) Fill tubes are screwed into the bottom of a 6"x4!'NPT double tapped reducer bushing which is located in a service fitting. The bottom of the fill tube is located four inches above the bottom of the tank with the open end slanted 45° The top of the 4" NPT service fitting is closed with a 4"' cast iron plug to facilitate shipment and toctinn FLI Fiberglass Bottom Sumps (optional) Bottom sumps provide a basin to trap contaminant liquids or solids from the primary tank that are heavier than the product stored in the tank. The sump must be located beneath a service fitting to facilitate pumpout. W TRU_-CHEW" Hydrostatic Monitoring System (optional) The brine filled interstice provides a positive pressure hydrostatic monitoring system to detect a leak. The pressure allows for accurate leak detection in the primary and secondary walls of the tank. Besides its continuous monitoring capability, TRU-CHEK" provides the opportunity to perform an EPA approved tank tightness test. See Xerxes Lit. Mo. 192. The FRP reservoir, which incorporates a 4" NPT monitor fitting, is factory installed and remains a permanent part of the tank. The FRP reservoir is provided at no charge with the purchase of TRU-CHEK'". If a standpipe is attached to the reservoir, the standpipe is not part of and is not employed in continuous monitoring of the tank, does not constitute part of the monitoring system and is not provided by Xerxes. 25,000 and 30,000 gallon tanks cannot be shipped with brine filled interstice. FNIAttached Manway Risers (optional) System I and System it The FRP attached manway riser (attached in the field) can provide a sealed catch basin to exclude groundwater from the service fittings and to catch product leaking into the primary piping system. Specify attachment to either 22" or 30" I.D. tank manway. All risers allow removal of the tank manway cover. System I has a 22" I.D. friction fit cover at the top of the riser (32" I.D. friction fit cover supplied upon request). System It has a 22" I.D. water tight bolt -on cover at the top of riser. Both systems include the necessary hardware, including the stud ring assembly and 2 extra gaskets. NOTE: Carefully select the size of the grade level street box—not supplied by Xerxes—to ensure an adequate interface.
