canyonkid, If you can use something a bit harder to shove in the hose, like a long broom handle, metal rebar, pipe, etc., Give it a squirt of vegetable oil to aid rock in slipping out and bang it against something solid or bang where the blockage is with a board. The end may be able to be spun off/unthreaded like a bolt(takes a bit of muscle) some do not come off because hose and pipe are molded into each other. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
