Dripline in your lawn

We generally state that sub soil irrigation for lawns is a job best left to the experts as many factors such as soil type, slope compensation, application rates etc, need to be considered.

Many councils require the backflow prevention device above be replaced with a RPZ backflow prevention device if using a "root intrusion guard" and using mains water supply. We encourage you to contact your local council for their specific requirements.

Item	Type
Root Intrusion Guard (replace Disc Filter)	Disc Filter - Trifluralin Impregnated MM 20mm (other Filters)
RPZ backflow prevention (replace Backflow Prevention)	AMES RPZ Device 20mm c/w valves & strainer FF (other Backflow Prevention)
