Well, after attempting several options including blasting the bladder and lines with a blow dryer, I decided to pull the filter out just for the heck of it. The filter is only a couple of months old so I didn't think that could be the culprit. Lo and behold, a small particle of ice popped out when I removed the filter. Put the filter back in and now it works better than it is ever has! Water is blasting out the door!
