The TetraPond Bottom Drain is an important accessory for achieving optimal water quality.

Installed at the deepest point of pond, this superbly engineered device encourages debris and waste to flow into a circular collection chamber where it is then carried away underground via standard 3" PVC pipe (not included) to a disposal area away from the pond.

Its dome-like shape is designed to force debris and waste to flow into a collection area while preventing debris from settling on top of the drain or away from the collecting vents. In seconds, accumulated debris is permanently removed.
