Does this sound right??

I had a 4" 180' submerse pump well done & the well guy hooked it to my lawn sprinkler system...he changed my zones from 4 to 2 cause he said that there was tons of water being pumped & this will alleviate the pump from running so now I have to water my small hedges for 25 minutes instead of only 8 minutes, since they are on the same zone.

Does this sound like standard procedure??
