Abstract
The valve spindle for a reverse osmosis (RO) filter system is housed in a filter head and attached to a mounting ring that also carries the replaceable RO cartridge. The RO spindle is locked in the head during normal operation, but can be easily removed, after removal of the cartridge, to permit spindle replacement or repair without disassembly of the head from the mounting bracket.
