A variable range sprinkler apparatus includes a sprinkler portion, a bypass unit housing a plurality of valves, and a water inlet portion. The sprinkler portion of the apparatus, which may be a rotary sprinkler unit, is attached to the bypass unit, and the bypass unit is coupled to the water inlet portion. Inside the bypass unit is a plurality of valves, at least one of which is adjustable, that are designed to open a water passage in the bypass unit.

A sprinkler apparatus comprising: a sprinkler portion;a bypass unit housing a plurality of ball valves; anda water inlet portion, whereinsaid sprinkler portion is rotatably attached to said bypass unit,said bypass unit is coupled to said water inlet portion,said plurality of ball valves is designed to open a water passage in said bypass unit,at least one of said plurality of ball valves is independently adjustable, andsaid water passage is a through-hole in said at least one of said plurality of ball valves that is disposed in an axial direction of said apparatus. 2. The sprinkler apparatus according to claim 1, further comprising: a water outlet unit having an aperture formed in an approximate center portion thereof, anda main axle extending downward from said sprinkler portion toward said water inlet portion of said apparatus, whereinsaid aperture of said water outlet unit is adapted to receive said main axle, andsaid water outlet unit is rotatable. 3. The sprinkler apparatus according to claim 1, said bypass unit comprising: an upper bypass housing;a lower bypass housing coupled to said upper bypass housing; anda bypass base plate coupled to said lower bypass housing and said water inlet portion,wherein said sprinkler portion is rotatably attached to said upper bypass housing. 4. The sprinkler apparatus according to claim 1, further comprising: a plurality of valve chambers arranged in a ring-like fashion inside said bypass unit, wherein each of said chambers accommodates one of said plurality of ball valves. 5. The sprinkler apparatus according to claim 1, further comprising: a fastener;a valve adjustment unit coupled to at least one of said plurality of ball valves via said fastener; andan aperture formed in an outside circumferential surface said bypass unit, whereinsaid valve adjustment unit is located outside of said bypass unit, andsaid aperture is designed to receive said fastener. 6. The sprinkler apparatus according to claim 1, wherein at least one of said plurality of ball valves is connected to a ball valve adjustment unit located outside of said bypass unit. 7. The sprinkler apparatus according to claim 2, said main axle comprising: a hollow water inlet portion having a water inlet aperture communicating said hollow portion to an inside portion of said bypass unit,a solid intermediate portion located above said inlet portion of said main axle, anda hollow water outlet portion having a water outlet aperture communicating said hollow water outlet portion to said inside portion of said bypass unit, whereinsaid intermediate portion is designed to redirect an incoming supply of water out of said water inlet aperture and into said bypass unit,said water inlet aperture is located below said plurality of ball valves, andsaid water outlet aperture is located above said plurality of ball valves. 8. The sprinkler apparatus according to claim 2, said rotatable water outlet unit comprising: a top outlet unit having a first portion extending from a second portion thereof; anda water outlet plate positioned inside said second portion of said top outlet unit , whereinsaid first portion has a smaller outside diameter than said second portion,said aperture extends through first portion, second portion, and said water outlet plate, andan outside diameter of said water outlet plate is substantially equal to an inside diameter of said second portion of said top outlet unit. 9. The sprinkler apparatus according to claim 8, said water outlet plate comprising: a plate portion;a protrusion extending upward from a top surface of said plate portion; anda cutout portion formed through said plate portion, whereina height of said protrusion is substantially equal to a depth of said second portion of said top outlet unit, andsaid cutout portion aligns with at least one water passageway outlet of said ball valve as said water outlet unit rotates. 10. The sprinkler apparatus according to claim 8, wherein a width of said cutout portion is greater than or equal to a sum of A and B, wherein A is a diameter of said water passageway outlet, andB is a minimum distance between adjacent said water passageway outlets. 11. The sprinkler apparatus according to claim 9, said outlet plate further comprising: a support ridge extending upward from said top surface of said plate portion. 12. The sprinkler apparatus according to claim 9, comprising: a plurality of said protrusions spaced apart in a ring-like manner, whereina passageway is defined by adjacent said protrusions, andsaid passageway is designed to communicate water from said bypass unit to said water outlet aperture of said main axle. 13. The sprinkler apparatus according to claim 2, further comprising: a generally cylindrical sleeve located between an inside surface of said bypass unit and an outside surface of a large diameter portion of said water outlet unit, whereinsaid sleeve is a water seal for said water outlet unit and reduces friction generated between said rotating water unit and said bypass unit. 14. The sprinkler apparatus according to claim 13, wherein said sleeve is attached to an inside circumferential surface of said bypass unit. 15. The sprinkler apparatus according to claim 1, wherein said sprinkler portion is a rotary sprinkler unit. 16. The sprinkler apparatus according to claim 1, wherein said bypass unit comprises six valve chambers and each of said valve chambers accommodates one of said plurality of ball valves. 17. A unit for selectively bypassing water, comprising: a housinga plurality of valve chambers positioned inside said housing; anda plurality of valve assembly units, whereinsaid plurality of valve chambers is arranged in a ring-like fashion,said valve assembly units are individually positioned inside said plurality of valve chambers,at least one of said valve assembly units is adjustable,at least one of said adjustable valve assembly units comprises a valve coupled to an adjustment unit, andsaid adjustment unit adjusts the position of said valve it is coupled to. 18. The unit for selectively bypassing water according to claim 17, wherein said valve is a ball valve and said adjustment unit is located outside of said housing and coupled to said ball valve via a fastener. 19. A method for adjusting water to flow through a sprinkler apparatus, comprising: adjusting a first ball valve of said sprinkler apparatus to a first position;adjusting a second ball valve of said sprinkler apparatus to a second position, whereinsaid first position influences a flow of said water exiting said sprinkler apparatus at a first time (T=1),said second position influences said flow of said water exiting said sprinkler apparatus at a second time (T=1+n),said first ball valve is adjusted independently from said second ball valve, andsaid first ball valve and said second ball valve are each disposed in an axial direction of said apparatus.
