Manifold construction

The final step in completing your system is to assemble the manifold. The 4" and 6" systems differ here as the injection manifold for the larger system is located at the same end as the drains whereby the smaller manifold is located at the opposite end. Shown at right is the 4" system's manifold which is assembled from the parts on page 19. It is a good idea to dry fit these parts together before you cement them with PVC glue. Many people opt to modify these parts slightly to accommodate differing layouts and pump selections.

The diagram below depicts the entire 4" system to illustrate how the manifold and plumbing is assembled.
