I have been asked to maintain an island for a subdivision. The only thing that I'm not sure about is a small irrigation problem they are having. They have some pots that they would like drip line ran to. The island has RB 1800s. It was always my understanding that drip lines needed to be ran on a seperate zone, correct or not? These 1800s have a plug on the side of the housing that I haven't seen before on other systems. I only need to water 2 pots! Does it have to be as difficult as installing another zone? I know you can convert the entire zone to drip using the 1800s and the drip kit, but come on...2 pots!
