Construction
| Slip Coupler: | |||
| Description: The slip coupler uses PVC bells and polyisoprene gaskets. The gaskets are placed in the corrugation valley on either side of the section to be repaired and the slip couplings are the slid over the gasket. Slip couplers should be supplied by the same manufacturer as the pipe. | |||
| Installation Instructions: Cut out the damaged area, make cuts in the center of the corrugation valley. Cut the replacement pipe section to the desired length. Trim any polyethylene burrs from saw cut. Excavate bedding from under the existing pipe cut ends. Lubricate the slip coupler bell ends then slide the slip coupler over the pipe cut end. Install a gasket on each cut end (4 per repair) in a valley corrugation. Lubricate the gasket. Do not allow the lubricated section to touch dirt or backfill. Slide the slip coupler over the gasket making sure to center the coupler. Carefully replace and compact bedding and backfill to provide proper support for pipe and coupler. | |||
