Timothy W Goins A & T Services ."Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." Jn 3:3 NASB Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Jn 3:5-6 NASB Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols. Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh.

His notes state that the maximum spacing would be 8'-6" o.c. for 2 1/2" pipe and 2'-0" o.c. for the 6" crossmains. Have we as sprinkler contractors been designing systems inappropriately all these years........LOL Mike
