Installation Instructions
After excavating the bottom floor of your pond to the desired shape, locate
where your Bottom Drain is to be installed and dig out an area approximately
15” by 15” wide and 7” to 8” deep. Next, excavate a trench away from the drain
location wide enough to accommodate the 4” drain pipe and the 1” aeration
pipe. The trench should be deep enough so the top of the Base flange is level
with the final grade of the pond bottom. Make sure the soil in the bottom of
the pond has been compacted properly to prevent any settling that could occur
in the future. Install the Base of the Bottom Drain making sure the top of the
Base is level with the grade of the soil in the bottom of thepond and level
the base. The hole for the base is dug deeper than you may need. Add soil as
needed to level the base. Install/glue the 4” pipe to the 4” Drain Fitting and
install/glue the 1” pipe for the aerator to the fitting on the side of the
Bottom Drain. Make sure the base is level and at the desired depth of either
level or slightly deeper than the bottom floor of the pond (slightly deeper is
preferred). Back fill the hole for the pipes and carefully backfill around the
Bottom Drain making sure the soil is compacted. Tip: you can temporarily set
or tape the aeration plate in place on top of the Base to prevent soil from
getting into it while working up to this point.
Install the pond liner in place over top of the Bottom Drain base to get it in
the proper place. Carefully pull back the liner, add a bead of silicone
sealant or lap sealant (Not Included) around the top of the Base then
carefully put the liner back in place. Line up the Liner Ring with the top of
the Base on top of the pond liner. Install the self tapping screws through the
holes provided in the Liner Ring to seal the liner in place. Next, cut the
liner section out of the center of the Liner Ring exposing the inside of the
Bottom Drain base. Assemble the aeration Disc, Plate, and Stand Pipe as shown
in the image at the top right of this page. The Stand Pipe comes cut to length
for a space of approximately 2” between the bottom of the plate and the liner
for the water to enter the Bottom Drain. If you desire a smaller space, you
may cut this pipe to the proper length to achieve the desired space for water
toenter the Bottom Drain. Once the pipe is at the proper length, glue the
bottom of the Stand Pipe into the fitting in the center of the Bottom Drain
Base. The installation is now complete. If the Bottom Drain Base needs to be
accessed for any reason, the Aeration Disc may thread off of the top of the
Stand Pipe for access. Evolution Aqua USA, Inc. 205 Route 22 East Unit D Green
