we replaced our fridge and after connecting the line the water pressure to my faucet which was beyond the saddle valve was cut in half. we changed the saddle valve and after that the pressure changed. the shower and the toilet are still at good levels. what happened?
If it is a small pipe the saddle may be partially obstructing the water flow. If you have copper, pex, or PVC plumbing it would not be hard to cut the pipe install a T and fit a 1/4" adapter or 3/8" depending on the size to your frige then you will not have a pressure reduction and in a few years (when the saddle would fail) you prevented the failure from happening.
