Do I need to somehow cut down the water supply going into the freezer

That would be my first option. My plumbing is copper and I used one of those self-tapping connections to tap into the water line and there is a twist on/off valve to let the water run to the fridge. I'd choke that down a bit to see if that helps-------IF you have that same type supply line assembly.
