Question 1

What is a micro-spray head used for in irrigation?

Accepted Answer

Low-volume fine-spray distribution for groundcovers and shrubs

Answer

Micro-spray heads deliver water in a fine low-volume spray pattern, applying more water than drip emitters but less than standard sprinklers, suited for shrubs and groundcovers.

Question 2

What is a bubbler emitter best suited for?

Accepted Answer

Delivering high flow directly to the base of trees or large shrubs

Answer

Bubblers deliver high flow rates (0.5–2+ GPH) directly at the base of trees or shrubs to fill a watering basin around the root zone.

Question 3

What is subsurface drip irrigation (SDI)?

Accepted Answer

Drip tubing buried below the soil surface to deliver water directly to the root zone

Answer

SDI places drip tubing below the soil surface to deliver water directly to plant roots, minimizing surface evaporation and eliminating above-ground hardware.

Question 4

What is the typical flow rate range for a standard drip emitter?

Accepted Answer

0.5–2 gallons per hour (GPH)

Answer

Standard drip emitters flow at 0.5–2 gallons per hour (GPH), delivering water very slowly to minimize runoff and maximize absorption.

Question 5

What is the purpose of a flush end cap at the end of a drip lateral line?

Accepted Answer

To allow periodic flushing of sediment and debris from the line

Answer

Flush end caps can be removed to allow water to flush sediment and debris from the ends of drip laterals, preventing emitter clogging.
