I am a professional water collector and install many filters. the o-ring was missing (should have been two anyway) and some of the black plastic part of the receiver at the top was also broken and it wasn't a remanufactured unit, it should have been new from the factory. It was in my shop for a couple of weeks before I installed it and now it's 10 days late to return it. Do yourself a favor and get a Geek Parts branded block instead, which is better in almost every way, including the receiver's brass threads.
