Not using the Integral Flow Check

What happens if you run a pump (Taco 0015e3) without the Integral Flow Check?
I finished my install a few weeks ago and had a leftover plastic doohickey with a spring. I meant to investigate what it was, but I completely forgot all about it. While cleaning up, I found it again. It took me awhile, but I’ve deduced that it’s the IFC for my circulator.
What’s it do? All I could find is, "a flow check prevents reverse flow and gravity flow.” Near as I can tell, my system is running fine. But reverse and gravity flow sound like bad things.
It wouldn’t be too difficult to install it. But I’d prefer not to if not using it isn’t harming anything.

    If you don't have any issues don't worry about it. Put it in a safe place where you will forget where it is LOL

    Probably not needed with the hydro sep, but doesn't hurt to have it installed.

    What kind of issues would I have? Heated water will flow back to the boiler? And that's bad because…

    I see no need for the check valve with those two positive stop Taco zone valves, unless I'm missing something?
