Secondary Containment System Installation When cutting out and replacing a secondary containment fitting, do not cut the internal primary product pipe. 1. Dissect the secondary containment fitting andthe secondary containment pipe around Its circumference as shown by the arrows. Remove the containment elbow. 2. Create a pipe nipple at least 7 inches (180mm) long on either side of the joint by making another cut arround ca thecirournference ofthe containment pipe. tll� cut 3. Using a sender. coarse file. or 3040 grit Emery cloth, remove surface 7---73 gloss from both ends of the nipples Cm and the containment pipe. Sanded area must be a minimum of 3 Inches (75 mm) in length. 4. Position the nipples between the new oontairnwrit elbow and containment sleeve couplings. -- ---- NOTE: It may be necessary to remove additional sections of the containment pipe to provide wp&' clearance for the coupling. r 5. Bond the elbow and containment sleeve couplings into place according to instructions. • Repairing Minor Pipe Damage to Pipe Follow the pipe patching instructions on page 14 of this manual when the damaged area is two inches (50 mm) or Patch --- 111111-41= t. ,t- •Kepainn -s Small repairs (pinhole leaks and leaks up to 1" in diameter using 8088 Repair Kit: 1. Take pressure off the system and dry the am around the leak. 2. Sand an area 3" minimum on each side of the leak. 3. Cut three 3Ox3! patches from the glass supplied with the 8088 repair kit. 4. Mix adhesive per instructions supplied in the kit. 5. Paint adhesive on the sanded area of the fitting. 6. Apply the fill* layer of glass and wet out with adhesive. The glass may be wet out and before it is applied to the leak area. T. Repeat the previous step and apply another layer of glass. 8. Cure per the time listed in the adhesive kit. Flange section orjoint leak repairs (overwrapping entire fitting) using 8088 Repair Kit: 1 . Take preemire off the system and dry the area around the leak. 2. Grind or cut flange sections off the clam shall secondary containment fitting and sand flush with the fitting body. C. If needled, mbt adhesive with filer to grout in any gaps or voids in the bond line or to create a smooth wrapping surface. 4. Per instructions in Me 8088 repair Idt, apply adhesive to to sanded area. Wet olut glass and wrap around the fitting as thiough it were a section of pipe, centering the first layer over the joint and extending 2" past the end of ttm fitting onto the pipe. Apply tension to squeeze adhesive through the glass layer. For elbows and too, silts may have to be cut In the center section for glow to lie flat. S. Repeat previous stop an the center of the joint and then the other side of thie fitting extending 2' over the end of the fitting. When starting the glass, overlap the first wrap a minimum of S. Repeat two previous steps until three layers of glass have been placed over the fittin g. 7. Cure per the time listed in the adhesive kit. • Repairing Extensive Pipe Damage When damage is less than 2" (50 mm) long but more than 2" around the circumference of the pipe, the following 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. Do not remove more than 7" (175 mm) of containment pipe. remove surlsce, gloss from both ends of the pipe. Sanded am must be a mirdmium of 3' (75 mm) in lengths. If contaminated, dew the sanded surfaces with solvent. 3. Mix the adhesive with filer. Assemble and bond the containments coupling into place and heat cure the bond. 4. After the repaired section has aired, pressure tog the system following the procedures on page 23. If damage is beyond these repair procedures, immediately contact your local FGS distributor for assistance. 24
