Atlantic Water Gardens 4' Flexible Hardscape Basin - Manual (Page 4)

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 in the bulkhead in
order to fill the basin to within a couple inches of the top of the basin (Figure 4).
4. Securing the Flexible Basin
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.
