I had the same "hammering" problem. For me, replacing the new filter with the old still produced the same results. It turned out that the water pressure was too high for the filter. I have a spigot attached to my water supply. I replaced the o-rings, turned off the water source and while the water dispenser was running, I slowly turned it up until the "hammering" started. Then I backed off on the spigot a bit until the 'hammering" stopped. No more issues.
