As you are filling the basin with water, continue smoothing out the wrinkles from basin as
you go, making sure to tuck the basin corners tightly into place. During this process, the
basin can be filled to the bottom of the bulkhead opening. For best results, temporarily
install a 1 ½" plug (not included) in the bulkhead in order to fill the basin to within a couple
inches of the top of the basin (Figure 4).
If the pump is being used inside the basin, the power cord will need to pass through the wall.
Pick a spot in the course directly above the top edge of the basin and ensure that there is a
1 ¼" sleeve or notched hole for the plug to pass through easily. This will be needed for pump
maintenance and winterization.

Securing the Flexible Basin
To secure the basin, place a solid bead of masonry adhesive along the top course of the
basin surround, with a generous dab also placed in the pre-punched glue points in the
basin flaps (Figure 5). Then carefully place the next course of stone, ensuring that the flaps
are pulled tight and there is no slack in the basin.
