I am starting to add a new zone to an existing system. Can you put spray heads and a drip system on the same zone?
If I used a retrofit pressure regulator what is the difference between using a xeri-bird 8 multi-outlet emission device and the 6 outlet manifold to start the drip part of the zone?
Either one will do, but the more expensive one requires you install emitters in it, which also allows you to select higher-flow emitters, which are a better match with regular sprinklers.
I have to second Tom on not putting a drip system on a zone.
This is coming from my personal experience. I'll try to give you an idea as to the problems I ran into early on when I mixed a drip system and rotor/impact sprinklers.
Lawn required waterings at different times depending on season and the amount of rainfall. The drip system required different waterings based on the plants.
The problems I had...
I drowned my wifes flowers and my lawn looked great or my lawn looked bad and the flowers looked bad.
Time was another problem with this because I had to keep adjusting my sprinklers to match what her flowers needed. It was a royal pain and was irritating me... Dont get me wrong I like the flower beds and everything. But my pride and joy is my bright green lawn.
So in the end I trenched some new lines to the flower beds and moved them to their own zone. The end result bright beautiful flowers and a nice green lawn.
