Method of supplying potable water to a recreation vehicle

A method of supplying potable water to a recreation vehicle, comprising the steps of:

• providing:
• a water filter module (100) including:
• a casing (110) defining an input (120) at a lower end thereof and an outlet (130) at an upper end thereof;
• a filtration medium (140) capable of purifying water, disposed within the casing (110);
• and
• a water filter adapter (10) including:
• a manifold (12) defining:
• an inlet port (14);
• an outlet port (16);
• at least one upstream conduit (18) in fluid communication with inlet port (14);
• at least one downstream conduit (20) in fluid communication with outlet port (16);
• wherein said at least one upstream conduit (18) and said at least one downstream conduit (20) facilitate fluid communication between the inlet port (14) and the outlet port (16);
• an integrated shutoff valve assembly (52) moveable between a first position in which the inlet port (14) and outlet port (16) are in fluid communication and a second position in which the inlet port (14) and outlet port (16) are not in fluid communication;
• coupling the outlet (130) of the casing (110) to the inlet port (14) of the manifold (12);
• coupling the input (120) of the casing (110) to a source of water;
• and
• directly coupling the outlet port (16) to an input connection (180) of a water storage system (190) of the recreation vehicle, without any hosing between the outlet port (16) and the input connection (180).
