Figure 1 illustrates the most common method used for water level control in small ponds.  A Premiers' Econo-Drain sleeve simply slides over the standard pipe.

In figure 2, the pond has been designed with outlet pipe set in dirt fill of the dam.  To install the Econo-Drain, select the drain size that corresponds with the outlet pipe size and bolt in place.  The intake pipe length, in all systems, is determined by the distance from the Econo-Drain inlet to the base of the dam.
