What is a micro-spray head used for in irrigation?
Answer: Low-volume fine-spray distribution for groundcovers and shrubs
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.
What is a bubbler emitter best suited for?
Answer: Delivering high flow directly to the base of trees or large shrubs
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.
What is subsurface drip irrigation (SDI)?
Answer: Drip tubing buried below the soil surface to deliver water directly to the root zone
SDI places drip tubing below the soil surface to deliver water directly to plant roots, minimizing surface evaporation and eliminating above-ground hardware.
What is the typical flow rate range for a standard drip emitter?
Answer: 0.5–2 gallons per hour (GPH)
Standard drip emitters flow at 0.5–2 gallons per hour (GPH), delivering water very slowly to minimize runoff and maximize absorption.
What is the purpose of a flush end cap at the end of a drip lateral line?
Answer: To allow periodic flushing of sediment and debris from the line
Flush end caps can be removed to allow water to flush sediment and debris from the ends of drip laterals, preventing emitter clogging.
What is 'in-line drip tubing'?
Answer: Tubing with emitters pre-installed at regular intervals inside the pipe
In-line drip tubing has emitters pre-installed at fixed spacing inside the tubing itself, eliminating the need to punch and insert individual emitters.
