I'm setting up a drip zone to water approximately 15 shrubs on the east side of my house. My irrigation system is fed directly from a well pump (no holding tank or anything like that).

I'm not sure if it's OK to run that zone by itself since it will be low flow and high backpressure to the well pump. Will it be hard on the well pump if I do this?

If I wire it up at the controller to run at the same time as one of the zones that waters the fescue, what about the timing? I would figure that a drip zone would need probably 30-45min? (My longest zone on the fescue is 20min, otherwise it runs off this damn clay soil.)
