How do I make a tap on a pipe wrapped in polyethylene encasement?

Direct service taps may be made right through the polyethylene encasement. The preferred method is to apply two of three wraps of adhesive tape completely around the wrapped pipe to cover the area where the tapping machine and chain will be mounted. The corporation stop is installed directly through the tape and wrap. Although this method is effective in eliminating damage to the polyethylene during the tapping operation, the entire circumferential area should be inspected for damage and repaired if needed.
