Frigidaire Refrigerator model FRS6LR5EM8 water dispenser water flow too strong! most online items refer to low or no water pleasure. I am not sure if replacing the water inlet valve will correct this issue.
You can reduce flow to the fridge by tightening the valve that supplies it. Trace the water line from the back of your fridge to your plumbing. If you find a valve that looks like this:
you can simply turn it clockwise a bit to restrict the flow. If you find a saddle valve like this:
then you will not have much ability to adjust flow at the valve. Your best bet then would be to replace the saddle valve with a proper tee and new valve with a compression outlet. While normally I'd recommend ball valves (sometimes called quarter-turn valves) for durability, they are not great for limiting flow, so here a multi-turn valve would be better.
