if you have a QEV you would want one between the QEV and the fill valve.
no use for one in a combustion.

who shoots water out of a combustion? for some reason that doesnt strike me as the greatest combination... maybe if you usd a sabot....besides, check valves are only up to like 1/2 inch...i think ive seen big pvc ones tho....

Uhh, yes there are uses for check valves in combustions... say you build a permanent venting system for the launcher using a mattress inflater. Connect the inflater to the check valve. When the combustion occurs, no damage occurs to the mattress inflater due to the check valve; however, the mattress inflater can still push air through the check valve to vent.

how exactlydoes a check valve work and why is it beneficial (SP) for a qev?

A check valve is just a valve that lets gas or liquid one way, but not the other, so the QEV won't fire when you disconnect your pump.
