REGFEIVED JA I� 17 2017 ENVIRONMENTAL HEALTH CEPARTMENT Flange Section or Joint Leak Repairs Using 8088 Repair Kit (Overwrapping Entire Fitting) 1. Take pressure off the system and dry the area around the leak. 2. Grind or cut flange sections off the clamshell secondary containment fitting and sand flush with the fitting body. 3. If needed, mix adhesive with filler to grout in any gaps or voids in the bond line or to create a smooth wrapping surface. 4. Per instructions in the 8088 repair kit, apply adhesive to the sanded area. Wet out glass and wrap around the fit- ting as though it were a section of pipe, centering the first layer over the joint and extending 2" (50 mm) past the end of the fitting onto the pipe. Apply tension to squeeze adhesive through the glass layer. For elbows and tee, slits may have to be cut in the center section for glass to lie flat. 5. Repeat previous step on the center of the joint and then the other side of the fitting extending 2" (50 mm) over the end of the fitting. When starting the glass, overlap the first wrap a minimum of 2" (50 mm). 6. Repeat two previous steps until three layers of glass have been placed over the fitting. 7. Cure per the time listed in the adhesive kit instructions. Repairing Extensive Pipe Damage to Red Thread IIA and Dualoy Fittings When damage is less than 2" (50 mm) long but more than 2" (50 mm) around the circumference of the pipe, the follow- ing repair procedures should be followed. If the pipe is buried, excavate a working area large enough to allow for repairs to be made. Use a secondary containment sleeve coupling to make this type repair. Containment sleeve couplings are 14" (350 mm) long. Caution: When cutting out extensive damage in the contain- ment pipe (only), be extremely careful not to damage the inter- nal product piping. 59
