The hanging assembly for quonset-style tunnels is 12″. For gothic-style tunnels 18″ hanging assemblies are included. This extra length is to put the sprinklers below the cross bracing to prevent water from collecting on the cross braces and dripping on the soil and crops below.
Are you trying to decide between a manual or automatic valve assembly? Well, it’s really a matter of dollars and minutes. Which one do you have more of? Time, or money? Both valves come with a 35 psi pressure regulator for optimum sprinkle performance.
Filters are a key component to hassle-less irrigation, as they keep sprinklers debris free. Disc filters are for those watering from ponds, creeks, or springs. Farms using city or well water will find the screen filter adequate.
