An irrigation filter system and method is provided. The system may have a body and a filtration subsystem and may separate fluid from detritus carried by the fluid. The fluid may be released onto a crop, while the detritus is collected by the filtration subsystem. A drain fixture may be operated to release the detritus from the irrigation filter system in response to at least one of the pressure of the fluid flowing in the system and gravity. In this manner, the detritus may be released without requiring the system to be shut down and/or disassembled.
