The first thing you will want to do is to determine the lowest point in the pond. Try to dig the bottom of your pond at a 30 degree downward slope. The reason for this is to try to funnel debris and have it collect in the same area of the bottom drain.

The depth of the hole should be the same height as the bottom portion of the bottom drain. NOTE: you may need to leave spacing for a 90 degree elbow depending on how you wish to install your PVC from the bottom drain into the pump.

Apply a light coating of silicone to the white gasket, which is attached to the lower half of the drain.

Install your underliner. With a razor blade, carefully cut around the outside of the drain.

Install your 45 Mil pond liner.

After the liner has been installed locate the spot where the bottom drain has been installed underneath the liner. Using your fingers, find the screw holes located in the gasket and rim of the lower half of the bottom drain. Mark the location of the holes with a white pencil. Using an awl or another puncturing tool carefully punch through the liner at the markings. Make sure you do NOT punch holes wider than the diameter of the screw holes in the lower half of the bottom drain.

Apply a light coating of silicone to the liner in a circular area directly covering the lower half of the bottom drain. Align the screw holes in the upper half of the bottom drain to the punctured holes within the liner. Using the provided screws attach the upper half of the bottom drain to the lower half. NOTE: The studs on the rim of the upper half of the drain should point upward; the flat surface of the rim should be flush with the liner. Do not over tighten at this point. The liner and underlayment should be perfectly sandwiched between both halves of the bottom drain, and the rim of the upper half should be level with the pond bottom.

After you have successfully secured both halves of the bottom drain, you must carefully cut the away the circular portion of the liner inside the drain making sure to trim the liner flush with the inside edge of the drain. Afterwards apply a light coating of silicone to the inside surface of the drain.

Fill the drain dome cover with sand or dirt until nearly full. Using PVC cement glue the plug into the bottom drain cover.

Align the drain cover to the bottom portion of the drain and press down firmly until the two halves are securely sealed. Do not glue or cement into place! The cover dome is meant to be removable for cleaning purposes.

Fill the pond with enough water to cover the bottom drain and check drain outlet for flow of water.

The shape of the cover dome is designed to force debris and water to flow into the drain inlet. Do not place potted plants, stones, or decorations on or adjacent to the bottom drain in a manner that could impede proper water flow.

Periodically remove the cover dome and inspect drain for blockage or tears in the liner around the edges of the drain. Also, make sure that the attachment screws remain firmly tightened.
