Water Gardening: Do you have or recommend a BOTTOM DRAIN in your pond?, 1 by SongsofJoy

This is the plumbing in the back of the filters to the external pump. Each line has a ball valve (2 inch) so that I can shut off flow to the pump individually.

The reason these barrels determine water level is because water seeks it's own level. If the barrels are lower than the pond, gravity would force the water to keep overflowing the barrels until the pond level matches the height of the barrels. Likewise, if the barrels are higher than the pond, the water level in the barrels will never go higher than the level of the pond.
