Spool valve manifold interconnect for a filter system

A spool valve manifold for use with a filter cartridge having an inlet/outlet portion comprising a cartridge inlet port and a cartridge outlet port, the spool valve manifold comprising:

• a valve housing having a housing inlet port and a housing outlet port;
• and
• a valve body comprising filter cartridge mounting surfaces, the valve body operatively positioned within the valve housing and being configured to rotate around a first axis relative to the valve housing, the valve body being configured to receive the filter cartridge via insertion of the inlet/outlet portion into the filter cartridge mounting surfaces in a direction about perpendicular to the first axis, such that, when the valve body is at a first rotational position relative to the valve housing the housing inlet port and the cartridge inlet port are in fluid communication via a first fluid flow path and the housing outlet port and the cartridge outlet port are in fluid communication via a second fluid flow path, and when the valve body is at a second rotational position relative to the valve housing, the housing inlet port and the cartridge inlet port are not in fluid communication and the housing outlet port and the cartridge outlet port are not in fluid communication.
