Unfortunately, many of the ways that sprayers get plumbed do not allow all of the components to work as they were intended.

Figures 1, 2, 3 and 4 provide examples of how different pump types and valve configurations can be plumbed to ensure each component works efficiently.

Figure 1 provides an example of a positive-displacement (diaphragm) pump plumbing set-up with two-way boom valves.

Figure 2 provides an example of plumbing a positive-displacement (diaphragm) pump set-up with three-way boom valves.

Figure 3 provides an example of a centrifugal pump set-up with two-way boom valves.

Figure 4 provides an example of a centrifugal pump set-up with three-way boom valves.
