I just installed a copper gate valve and remembered I'd read here that
copper is a no-no in ponds because it can kill the fish.

What's the opinion he will one short length of copper (actually,
it's brass, that has copper in it) cause problems in my 400 gallon
pond? I wanted a PVC valve, but it wasn't available at the time of my
purchase...


Copper is poisonous to fish, although it depends on how much gets into
the water. A 400 gallon pond is small, so it would be better to
replace the valve with a plastic valve.
