The present invention relates to novel devices and methods of filling tanks designed for holding non-hazardous fluids, especially tanks on recreational vehicles. In a preferred embodiment, the tank to be filled is a water tank. The device of the present invention incorporates several novel and non-obvious features to create a device that permits the filling of tanks in a hands-free manner while keeping water waste to a minimum and preventing the damaging of tank, fill neck or other tank or fill components due to the over filling of the tank.

1. A device for filling tanks, said device consisting of: an essentially cylindrical housing having a first opened end having a screw fitting and a second opened end having a barbed fitting, said cylindrical housing also having and positioned between said first opened end and said second opened end
1. A device for filling tanks, said device consisting of: an essentially cylindrical housing having a first opened end having a screw fitting and a second opened end having a barbed fitting, said cylindrical housing also having and positioned between said first opened end and said second opened end i) a filter assembly, ii) a shut-off valve and iii) a self-regulating flow control device, said cylindrical housing further comprising a vented cap, said vented cap positioned between said first opened end and said second opened end and designed to couple said device to a tank or to a fill neck of said tank. 2. The device of claim 1, wherein said filter assembly and shut-off valve are proximal to the screw fitting end. 3. The device of claim 1, wherein said self-regulating flow control device is proximal to the barbed fitting end. 4. The device of claim 1, wherein said self-regulating flow control device is downstream of said filter assembly and said shut-off valve. 5. The device of claim 1, wherein said screw fitting is sized to attach to a garden hose. 6. The device of claim 5, wherein said screw fitting is sized to attach to a garden hose having a diameter of ½ inch, ⅝ inch, ¾ inch and 1 inch in diameter. 7. The device of claim 1, wherein said barbed fitting is fitted to a slip hose. 8. The device of claim 1, wherein said shut-off valve is a ball valve. 9. The device of claim 1, wherein said device is capable of being disassembled into component parts. 10. The device of claim 1, wherein said tank to be filled is located on a recreational vehicle. 11. The device of claim 10, wherein said tank is a fresh water tank. 12. The device of claim 1, wherein said cylindrical housing is made at least in part from a metal selected from the group consisting of brass, copper, steel, stainless steel, nickel, bronze, aluminum or an alloy or mixture thereof. 13. The device of claim 1, wherein said cylindrical housing is made at least in part from plastic. 14. A device for the filling of fresh water tanks on recreational vehicles, said device consisting of: a. a cylindrical device, said device having i) a barbed hose fitting, ii) a hose swivel, said hose swivel having an on-off valve and a filter, iii) an attachment means for attachment of the device to a tank opening wherein said attachment means also having a means for venting said tank to be filled, iv) a self-regulating flow control washer and, v) a flexible hose;b. wherein i) said female barbed hose fitting is connected to said hose swivel via a screw fitting, ii) said self-regulating flow control washer is positioned between said female barbed hose fitting and said hose swivel, iii) said flexible hose is connected to the barbed end of said female barbed hose fitting and, iv) said attachment means for attachment to said tank opening is positioned between said barbed hose fitting and said hose swivel. 15. A method for filling a tank with fluid, said method comprising: a. attaching to a tank fill opening a fill device consisting of: i) a cylindrical housing having two ends wherein one end having a barbed fitting and the other end having a screw fitting, said cylindrical housing ii) proximal to the end comprising the screw fitting a filter assembly and a shut-off valve and iii) proximal to the end having the barbed fitting a self-regulating flow control washer, said cylindrical housing further having a vented cap, said vented cap positioned between said bathed fitting and said screw fitting and designed to couple said device to said tank or to a tank fill neck;b. attaching to the screw fitting of said cylindrical housing a hose sized to fit said screw fitting;c. turning on at the source the fluid to be placed into the tank;d. opening said shut off valve located proximal to said screw fitting;e. filling the tank to a desired level;f. turning off said shut off valve located proximal to said screw fitting;g. turning off fluid at source;h. disconnecting said hose from said screw fitting of said cylindrical housing; andi. removing said fill device from said tank. 16. The method of claim 15, wherein said tank to be filled is located on a recreational vehicle. 17. The method of claim 16, wherein said tank is a fresh water tank.
