What type of piping is located between the control valve and sprinkler heads?

The type of piping located between the control valve and the sprinkler heads is lateral piping. Lateral piping serves as the distribution system that carries water from the control valve directly to the individual sprinkler heads. This section is crucial for the effective delivery of water to the specific areas being irrigated.

Lateral piping is designed to handle lower pressure than the main line, which brings water from the source to the irrigation system. It is also more flexible in terms of layout, allowing the installation of multiple sprinkler heads at varying distances and configurations to optimize coverage and ensure that the water reaches all intended areas of the landscape.

In contrast, main line piping refers to the primary supply of water from the source, while supply line often indicates any conduit supplying water to the system. The return line typically refers to piping used in systems that recycle water, which is not applicable in the context of standard irrigation system layout between valves and heads.
