13. Screen
Cut the screen into a circle, making it at least 20" larger than the barrel. This
will allow for a 10" overhang. More overhang is better than less overhang. Be
generous.
**Important Note!!
The screen will "cup" the gravel. It should be carefully held up while pouring
the gravel into the barrel. If this is not done, the gravel will fall to the bottom of
your barrel and will not work properly.
14. Overflow Pipes
Measure from the top coupling to the place where you want the water to fall into the pond.
Cut a piece of 2" pipe and insert it into the coupling and glue.
15. Set up
Fill with gravel, be careful to keep the screen edges up along the sides of the barrel.
The barrel will appear to have more gravel in it then it actually does, remember the milk
crate is holding the gravel about 10" off the bottom of the barrel, creating a water
reservoir on the bottom.
