Advantage Bottom Drain Covers
Features:
- Easiest drain available to install.
- Easiest drain to service if drain begins to plug.
- Drain weighs 22 pounds so the fish cant move it.
- Leg height can easily be adjusted for more clearance if needed.
We recommend
using a Hakko 40
Air Pump to drive a single bottom drain cover with air diffuser. A
Hakko 60 Air
Pump will be needed in order to get enough air when driving two bottom
drains with air covers.
Installation
Instructions
Installation instruction for
Standard Drain Cover on concrete ponds: For
concrete ponds simply extend bottom drain pipe vertically through concrete
and cap for pressure testing. Make sure concrete around drain pipe is
level for at least a 9 radius. This will allow proper clearance when
cover is installed. After concrete is plastered, simply cut drain pipe off
flush with pond bottom and place drain cover over drain hole.
Installation instruction for
Standard Drain Cover on liner ponds: For
liner ponds remove dirt around bottom drain pipe 6 deep with at least a
9 radius. Install the bottom drain bulkhead fitting 1 below the pond
bottom surface. Pour concrete in area around bottom drain and contour as
per the following drawing. Let the concrete dry, install liner and then
place drain cover on liner over pipe opening.
Note: Placing 6 of concrete around the
bottom drain will help to keep the bottom drain from floating upward if in
the future the pond water was lowered and the liner began to bubble up due
to ground water behind the liner. This could save you having to tear up
your whole liner if the drain got dislodged.
Installation instruction
for Drain Cover with Air Diffuser: Follow
instructions for standard drain cover except add a ½ inch PVC air line
extending into the pond 12 inches from the center of the drain pipe.
Connect ½ inch line to drain cover with the plastic hose included with
drain cover.
