My current pond design (It hasn't changed in about 8 weeks. Those of you
that follow the BV pond escapade, know what kind of feat that is) is going
to be about 2200 gallons, with about a 300 gallon VF. Upstream from the VF,
I plan to have a pump house that will draw from the VF and empty into the
main pond. The main pond will feed the VF via a skimmer and a bottom drain.

Should I have a check valve in the output pipe to prevent water from
returning via the send? Everything in this system will be roughly on the
same level, so I do not think I will have problems with drainage if the pump
dies.

I love to read your pond plans. I still have the first
sketch of mine. It reminds me of all the changes I did
after the first plans were finished. If you look at my
web page you'll see what I mean.
