I have installed a sprinkler system on a dedicated well 70 ft. deep, 1 hp pump-3wire, 52 gal air tank. The pump specs are 12.5 gal per minute for 80 ft. The system will run for 30 minutes before losing pressure, when pressure builds back it will run for 15 minutes, and shorter periods each time after, unless it is shut off for over an hour.

Thanks
Danny
