Because the 6' AquaDam® was placed on top of a smaller coupling collar, a 4' AquaDam® will now abut up against it perfectly, with no loss of support. 

The 4' AquaDam® is now unrolled and inflated as normal, and because its collar was mounted at a 90 degree angle prior to its attachment, it will not have to be turned.

Throughout the project, the inflation pumps were placed in plastic children's pools to prevent any gasoline or oil from accidentally contaminating the water.
