Nedra,

It's a Tetra 3 inch, plumbed through the liner with a control valve at the
skimmer. I put my pump (K6 Sequence) and filter (Fluid Art Bead) in my
basement for ease of maintenance. I purchased it through Creative
Waterscapes (along with my skimmer and bead filter). Although my set-up
seems to work great, I built the whole pond without the information I've
gleaned from this forum. I could have saved a lot of money, and a few
headaches had I known about it!

Hi Mark,

What is the size of your drain? 2, 3, or 4 inch? and where did
you buy it?

If you use a skimmer box, you can plumb the drain right into the front
of
the box (underneath the skimmer opening) without needing to go "up and
over."

I have one bottem drain in a 15'x30'x4' and it works great. A lot will
depend on the contour of the bottom of the pond.

You can have the pipe go up and over, but you need to install a Tee
and
valve at the top to let air out. Put a backflow preventer between the
top
and the bottom drain location to prevent water running back to the
pond.
Force water in backwards from the pump or settling basin until all air
is
out of the top location, and then it will siphon. Periodically, you
will
need to do the forcing of the water, to evacuate the air, since some
air
is
in the water and that is the location of the highest vacuum, and some
air
will separate from the water and accumulate in that location.

I would like to know if anyone can help me out with a couple
questions.
I
would like to add a bottom drain to my pond with having the
plumbming
on
top
of the liner, is this possible? It's to late to redo the pond and
less
cost
effective. Is there any ideas or suggestions, any help would be
appreciated.
My pond is currently 12,000 gallons. And i would like an easier time
of
cleaning the bottom.
