Keep pulling until the new inner tube comes well out of the ruptured tube.

A close-up view of the end of the new inner tube. It has been tied tightly and duct-taped into place. If the rope slips off the end of this tube while it is being pulled through the AquaDam®, there is no way to finish the re-lining process, and there is also no longer a string line inside. The AquaDam® would then have to be completely removed from the water to repair it. Make sure the rope is secure!  

Once the new liner is through, remove the rope and begin filling as normal.

It is also very important that the roll of new plastic comes off of the roll smoothly and evenly. If it falls, it may get holes in it, causing further delays. Pulling the rope slowly and easily is the best way to ensure success.
