Drain first skimmer 2nd.

I would run the drain back into the filter. If you are building on uneven
ground I would
include an outlet about a foot below ground level. Instead of an expensive
valve I cap mine with a coupler and enough pipe to extend it above the level
of the
pond. When I pull off the extender pipe the water starts slowly and picks
up speed
untill it is gushing out. The bottom of the pond is bowl shaped around the
drain.
I open the pipe about once every week or two. The crud that comes out looks
like it belongs in a septic tank. Esp good when a plant tips over.

If you are using a EPDM do not fear cutting a hole in the liner for a drain.
A lot of people have problems with waterfalls and streams but one seldom
hears about problems regarding drains. Check out the site(s) where people
have used toilet flanges to attach to the pipe.

Since people seldom read past the first screen I will stop here.

OK, I am definitely going to include a skimmer and a bottom drain in the
pond. Does it make sense to have the output of each of these run back
through the veggie filter or right back to the pond?
