I have a submersible 3/4 HP pump that supplies my home and garden. I put
in
an automatic lawn sprinkler system and the pump goes on an off during the
watering cycle, turning on and off. To prevent this do I increase or
decrease the flow to the lawn sprinklers?


Is this a demand system or one with a water tank ? If it is one with a tank
you could probably prevent it by going to the trouble of installing a much
larger tank - but why bother ?
