Buying Guide

Match valve size to your supply

Confirm pipe and valve thread sizes (3/4 in, 1/2 in, FPT) so manifolds and anti-siphon valves fit your existing plumbing

Choose expandable manifolds

Four-valve preassembled manifolds simplify installation and let you add zones without reworking the main line

Prioritize anti-siphon protection

Anti-siphon valves prevent backflow into potable water and are required or recommended in many municipalities

Consider rotor vs. spray heads

Pro rotors cover larger turf areas with adjustable throw, while fixed sprays and shrub adapters suit flower beds and tight spaces

Keep replacement parts handy

Common parts such as jar-top diaphragms and adapter packs extend system life and reduce downtime during repairs
