1. An assembly, comprising:
a magnetic rod guide including
a base for attachment to a part of a filter,
a through aperture through which a magnetic rod can move, and
resilient engagement means including at least one resilient latch on the guide for releasably holding the magnetic rod in one or more fixed positions relative to the guide,
each of the at least one resilient latch further being adapted to allow movement of a magnetic rod through the through aperture in either direction, for insertion into the filter or withdrawal from the filter into one of the fixed positions, in which a first seal is provided inside the through aperture for providing a water-tight seal between the magnetic rod guide and magnetic rod; and
a magnetic rod being cylindrical and sized to slide through the aperture in the guide and into a magnet sleeve of the filter and having one or more co-operating engagement means for engaging with the resilient engagement means of the guide, one end of the magnetic rod including a magnetic rod handle portion, for use in moving the magnetic rod through the guide, the magnetic rod handle portion being disposed on one side of the guide, the magnetic rod being movable relative to the magnetic rod guide and movable into a position where the magnetic rod is held by the resilient engagement means, and where at least one magnet in the magnetic rod is disposed to the same side of the magnetic rod guide as the handle portion
wherein at least a portion of an upper end of the magnetic rod comprises a material breathable but waterproof for allowing air to flow from a vent to an exterior of the filter.
