Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Yes you can remove/replace th head without draining the system. Make sure the head is de-energized (you feel resistance when you pull the lever down) then just twist it and it will release and come off.
