Drain fittings for irrigation systems
A drain fitting for use in an irrigation system for draining water from the irrigation system, regardless of pipe size in the irrigation system, generally includes a grip portion and a neck coupled to the grip portion. The neck defines a first engagement portion having a first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the first diameter of the first engagement portion, and a second engagement portion having a second diameter, different from the first diameter, for coupling the drain fitting to a pipe of the irrigation system having a diameter corresponding to the second diameter of the second engagement portion.
1. A drain fitting for use in an irrigation system for draining water from the irrigation system, the drain fitting comprising:
first and second threaded engagement portions each configured to couple the drain fitting to the irrigation system, the first engagement portion having a first diameter and the second engagement portion having a second diameter different from the first diameter; and
a screen disposed at least partly within the first engagement portion;
a channel extending longitudinally through the first and second engagement portions for draining water from the irrigation system when the drain fitting is coupled to the irrigation system, the channel defining an interior portion of each of the first and second engagement portions, an exterior portion of each of the first and second engagement portions comprising thread configured to couple the drain fitting to the irrigation system;
a first screen coupled to the first engagement portion, the first screen configured to inhibit debris from entering the channel at the first engagement portion; and
a second screen coupled to the second engagement portion, the second screen configured to inhibit debris from entering the channel at the second engagement portion.
2. The drain fitting of claim 1 , wherein the second screen is coupled to an end portion of the second engagement portion, and/or wherein the second screen is coupled to an end portion of the second engagement portion.
3. The drain fitting of claim 2 , wherein the first screen is raised generally above the end portion of the first engagement portion, and/or wherein the second screen is raised generally above the end portion of the second engagement portion.
4. The drain fitting of claim 1 , wherein the first engagement portion is removable from the drain fitting.
5. The drain fitting of claim 1 , further comprising a valve assembly for selectively allowing and inhibiting drainage of water through the drain fitting.
6. A drain fitting for use in an irrigation system for draining water from the irrigation system, regardless of pipe size in the irrigation system, the drain fitting comprising:
a grip portion;
a neck coupled to the grip portion;
a first screen; and
a second screen;
the neck defining a first engagement portion having a first diameter capable of coupling the drain fitting to a first pipe of the irrigation system having a diameter corresponding to the first diameter of the first engagement portion, the first screen coupled to the first engagement portion;
the neck defining a second engagement portion having a second diameter, different from the first diameter, capable of coupling the drain fitting to a second pipe of the irrigation system having a diameter corresponding to the second diameter of the second engagement portion, the second screen coupled to the second engagement member at a location adjacent the first engagement member; and
the first engagement portion coupled to the second engagement portion, and the second engagement portion coupled to the grip portion such that the second engagement portion is disposed longitudinally between the grip portion and the first engagement portion.
7. The drain fitting of claim 6 , wherein the first screen is coupled to an end portion of the first engagement portion of the neck and disposed at least partly within the first engagement portion.
8. The drain fitting of claim 7 , wherein the first screen is raised generally above the end portion of the first engagement portion.
9. The drain fitting of claim 7 , wherein the second screen is coupled to an end portion of the second engagement portion of the neck.
10. The drain fitting of claim 9 , wherein the second screen is raised generally above the end portion of the second engagement portion.
11. The drain fitting of claim 7 , wherein the first engagement portion is removable from the drain fitting.
12. The drain fitting of claim 11 , further comprising a valve assembly for selectively allowing and inhibiting drainage of water through the drain fitting.
13. The drain fitting of claim 7 , wherein the grip portion of the drain fitting includes an outlet for discharging water from the drain fitting, the drain fitting further comprising a filter disposed generally over the outlet for inhibiting unwanted debris from entering the drain fitting through the outlet.
14. A drain fitting for use in an irrigation system for draining water from the irrigation system, the drain fitting comprising:
at least two threaded engagement portions, each having a different diameter and each capable of coupling the drain fitting to a different pipe of the irrigation system, wherein each of the different pipes of the irrigation system has a different diameter;
a channel extending longitudinally through the at least two threaded engagement portions for draining water from the irrigation system when the drain fitting is coupled to one of the pipes of the irrigation system, the channel defining an interior portion of each of the at least two threaded engagement portions; and
two or more screens disposed in communication with the channel, a first one of the two screens coupled to an end portion of one of the at least two threaded engagement portions and a second one of the two or more screens coupled to an end portion of another one of the at least two threaded engagement portions.
15. The drain fitting of claim 14 , wherein at least one of the at least two threaded engagement portions is removable from the drain fitting.
16. The drain fitting of claim 15 , wherein at least one of the two or more screens is disposed at least partly within at least one of the at least two threaded engagement portions.
17. The drain fitting of claim 16 , wherein at least one of the two screens is disposed generally within the at least one of the at least two or more threaded engagement portions that is removable from the drain fitting.
