new to the forum. I am looking at putting in a well and an irrigation system also. Can a submersible pump connect directly to the sprinklers without a pressure tank. I realize that if the pump ends up pumping at say 13 gpm that the sprinkler zones would each have to be designed around this 13gpm fig. How much leeway is there also if the pump puts out 13gpm and the sprkler system is designed for 12gpm will that hurt the pump? Thanks for your help.
