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 that a problem, going on and off like that? because most water pumps
do that. I'd say increase. if it cuts off it is because the pressure
is to high.
