Drain base is installed under the liner, usually in the deepest part
of the pond. Determine placement and excavate. Bottom drain
and plumbing use a PVC 4" male adapter or reducing adapter to
connect to PVC pipe (not included). Teflon tape threads of male
adapter and tighten securely to prevent leaking. Connect
to barbed elbow (installed) and clamp securely prior to glueing
bottom drain to PVC pipe. Failure to clamp securely could result in
leaking. Extend tubing out beyond edge of liner to be connected
to air pump. Be sure air compressor sits higher than water level in
pond after tubing is connected. Recommended air flow is 0.5 - 1.5 cfm.

After installing liner, find drain base. Carefully cut an 8" hole
in the liner directly above center hole in drain base. Be sure not to cut the
hole larger than the center hole in the drain base. Lift the liner up a few inches
and inspect the top flange of the drain base. Remove any sand or debris that
may have gotten on the flange when pulling the liner into place. Place a thick
bead of silicone around the middle of the flange on base and then lower liner.
Be sure underlayment fabric is cut back so it does not lay on the drain base -
liner needs to lay directly on base.
