Weight, particularly suited for use in irrigation systems, includes a body having a chamber with inner and outer walls. The chamber is sized and configured for receiving a fluid such as water, storing the water in use, and adding to the weight of the overall device. The unfilled weight is lightweight when empty for shipment, and relatively heavy, in use. A portion of water coming into the weight is diverted, such as when irrigating a field and the weight is connected to an irrigation line. Such diverted water fills the chamber and increases the service weight. The weight may include an outlet configured for attaching to an irrigation sprayer head. When the flow of irrigation water is stopped, the weight retains some water, maintains the desired service weight, and prevents undesired movement of the weight and associated sprinkler head.

1. A weight, comprising;a) a body including an inner wall and an outer wall;b) the inner wall being provided at a distance from the outer wall, the inner and outer walls defining a chamber;c) an inlet fluidly connected to the chamber, the inlet being configured for being connected to a fluid supply;
1. A weight, comprising;a) a body including an inner wall and an outer wall;b) the inner wall being provided at a distance from the outer wall, the inner and outer walls defining a chamber;c) an inlet fluidly connected to the chamber, the inlet being configured for being connected to a fluid supply;d) an outlet fluidly connected to the chamber, the outlet being configured for being connected to a liquid distribution device;e) the inlet being configured and disposed so that when a liquid enters the inlet, in use, a portion of the liquid enters and at least partially fills the chamber, and a further portion of the liquid which enters the inlet exits to the outlet;f) the chamber being sized and configured so that the chamber serves as a weight when at least partially filled with the portion of the liquid which enters the chamber, in use;g) the chamber being configured and disposed so that, in use, when the body is at least partially upright and a liquid flow is stopped, the chamber remains at least partially filled with a liquid, and the at least partially filled chamber functions as a weight and causes the outlet and a liquid distribution device connected to the outlet to remain in a desired orientation; andh) the chamber being configured and disposed so that, in use, when the body is at least partially upright and a liquid flow is maintained, the chamber remains at least partially filled with a liquid, and the at least partially filled chamber functions as a weight and causes the outlet and a liquid distribution device connected to the outlet to remain in a desired orientation. 2. A weight as in claim 1, wherein:a) the inlet is located in an upper portion of the chamber and the outlet is located in a lower portion of the chamber. 3. A weight as in claim 1, wherein:a) the inlet is located above the middle of the chamber and the outlet is located below the middle of the chamber. 4. A weight as in claim 1, wherein:a) the chamber is substantially symmetrical. 5. A weight as in claim 1, wherein:a) the chamber is substantially cylindrical. 6. A weight as in claim 1, wherein:a) the body includes a plastic. 7. A weight as in claim 1, wherein:a) the inlet is configured for being attached to a flexible tube. 8. A weight as in claim 1, wherein:a) the inlet is configured for being attached to an irrigation hose;b) the outlet is configured for being attached to an irrigation sprayer; andc) the desired orientation is a substantially downwardly extending orientation so that a liquid sprayed by an irrigation sprayer attached to the outlet is sprayed substantially downwardly. 9. A weight as in claim 1, wherein:a) the chamber extends substantially around the perimeter of the body. 10. A weight, comprising;a) an inner wall and an outer wall;b) the inner wall being spaced apart from the outer wall, and defining a chamber;c) an inlet fluidly connected to the chamber, the inlet being connectable to a fluid supply;d) an outlet fluidly connected to the chamber, the outlet being connectable to a liquid distribution device;e) the inlet being configured so that when a liquid enters the inlet, a portion of the liquid is directed to, enters, and at least, partially fills the chamber, and the rest of the liquid exits to the outlet;f) the chamber including an upper portion and a lower portion, and being configured so that the chamber serves as a weight when at least partially filled with the portion of the liquid which enters the chamber;g) the chamber being configured to at least partially fill with a liquid, in use, so that when the upper portion of the chamber is at least as high as the lower portion of the chamber and liquid flow is maintained, in use, the at least partially filled chamber functions as a weight and causes the outlet and a liquid distribution device connected to the outlet to obtain a desired orientation; andh) the chamber being configured to remain at least partially filled with a liquid, in use, so that when the upper portion of the ch amber is above the lower portion of the chamber and liquid flow is stopped, in use, the at least partially filled chamber functions as a weight and causes the outlet and a liquid distribution device connected to the outlet to remain in a desired orientation. 11. A weight as in claim 10, wherein:a) the inlet is located in an upper portion of the chamber and the outlet is located in a lower portion of the chamber. 12. A weight as in claim 10, wherein:a) the inlet is located above the middle of the chamber and the outlet is located below the middle of the chamber. 13. A weight as in claim 10, wherein:a) the chamber is substantially symmetrical. 14. A weight as in claim 10, wherein:a) the chamber is substantially cylindrical. 15. A weight as in claim 10, wherein:a) the body includes a plastic. 16. A weight as in claim 10, wherein:a) the inlet is configured for being attached to a flexible tube. 17. A weight as in claim 10, wherein:a) the inlet is configured for being attached to an irrigation hose;b) the outlet is configured for being attached to an irrigation sprayer; andc) the desired orientation is a substantially downwardly extending orientation so that a liquid sprayed by an irrigation sprayer attached to the outlet is sprayed substantially downwardly. 18. A weight as in claim 10, wherein:a) the chamber extends substantially around the perimeter of the body. 19. A weight as in claim 10, wherein:a) a barb is provided on the inlet, the barb being configured for engaging a hose. 20. A weight as in claim 10, wherein:a) threads are provided on the outlet.
