What would cause a water hammer-type of forceful turning ON at one sink but not others?
Is it a faucet problem?

Only quick closing (solenoid) valves require chambers. This would only affect washing machines, dishwashers, and ice makers.Assuming it was piped correctly your air chambers are likely full or have a leak. Turn off the water and drain the system (turn the water on everywhere so it sucks air), that should fill all your air chambers. If the piping doesn't have air chambers on that one there's your problem, you'll need to add them then.
