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?

If you are watering for any length of time, the pump HAS to go on and off.
Once the pressure gets to a certain low-pressure setting, the pump has to
kick back in and start pumping again. I don't see how you could water a
yard larger than 200 sq feet without this happening.

Or perhaps I have misunderstood your question.........................

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.

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 ?
