homeowner installing 4 shallow wells here,,,me – in florida.
Plan is to grow/water the yard grass with one 3/4 or 1-hp centrifugal sprinkler pump.
Slowly will be adding sprinklers and pipe thru bunches of roots for a partial inground sprinkler system.(lots of trees and darn roots, dont know about them roots and my shovel yet). Initially (& right now with city water) sprinkling with ,, hoses and chicker-sprinklers. Will use rotor heads in sprinkler system mostly eventually.
my ‘Question is about the pump…. I look around and see that most neighbors have little 2-gal (or so) Air Tanks sitting on top of their lawn pumps…
What’s purpose of this Tank… do I really need one ?
It is a combination storage/air tank. Its purpose is to keep your pump from burning out the motor. Without it your pump will turn on and off several times a minute unless your system is large enough to use all the water the pump is producing. Buy a packaged pump system and it will have the pump, tank, and controls already assembled.
