Once the AquaDams® were back in position, the water levels had to be evened out again so that the dam would stay in place. 

Water was then pumped back into the large AquaDam® to help hold it in place and to prevent the new inner tube from hanging up on its way through. 

Every large AquaDam® has a string line running through each inner tube for just such occasions. The string line is not strong enough to pull the new liner through; it is only used to thread a piece of ½" rope through the AquaDam®.
