Anyone know of a place to get in-line check valves in Cedar Rapids area? I am needing some for my co2 line. I ordered a few online but got 3/16' on accident instead of 5/16" hoping to not have to wait another week to get my fridge complete. I really don't want to go without as I have heard horror stories of beer backing up into the line and getting to the regulator.

Nevermind, I think I resolved my problem. Overcomplicated things and should have just checked the valves I bought. they appear to be check valves after some testing. should have thought of that first!

Don't be too worried. I had check valves seize up on me in my old CO2 splitter. I took it apart and removed the check valves. I have not had any issues. I do have one check valve in front of the regulator just in case though.
