SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Todd,

You install the EZ-Green unit after the pump outlet and after the backflow prevention device (if you have one) but before the mainline splits up top feed the zone valves. You install a tee in the mainline to allow a 1/2" line to feed the top of the EZ-Green unit. Another 1/2" line comes out of the bottom of the EZ-Green unit and feed back into the mainline just past where you put the first tee. Therefore you install two tees in the mainline altogether which provides a slip stream of the water to pass through the EZ-Green unit (not the entire mainline water flow.). The fertilizer tablets are designed to slowly dissolve over time releasing fertilizer evenly over the property.
