Abstract: A fill tube for a water filled plant protector is formed by folding the top edge of the outer wall of the protector between the inner and outer walls and capturing the edge with the welds that create the vertical columns. The protector is filled through a port in the tube. Air is vented as the columns fill with water through the open top of each column.

Abstract: A waste water filter comprises a shield comprising a vertical peripheral wall defining a shield interior. The shield further includes an inlet for the entry of unfiltered wastewater into the shield interior. A shield filter element is disposed within the shield interior. An outlet in fluid communication with the second interior location for discharging filtered waste water is also included into the waste water filter. The shield filter element includes at least one filter surface having filter surface openings for the passage of relatively clear water while restricting the passage of solids larger than the openings. The shield filter element, when disposed within the shield, separates the shield interior into first and second interior locations. Unfiltered or partially filtered waste water in the first interior location is separated from filtered waste water in the second location by the shield filter element. The shield filter element is removable from the shield.

Abstract: The present invention is a waste water filter for use in a septic tank. The waste water filter includes a shield comprising a vertical peripheral wall substantially impervious to the passage of unfiltered waste water. The shield includes an opening for the entry of unfiltered waste water into the interior of the shield. A filter element is disposed substantially within the shield interior. The filter element includes a filter surface having filtering openings for restricting the passage of waste water solids of a size larger than the filtering openings, while allowing the passage relatively clear water. A reservoir within which filtered waste water may be temporarily maintained is disposed at least partially within the interior of the shield. The reservoir includes at least a first vertical peripheral wall defining a chamber. The filter element may be removed from the shield without the separation of the reservoir from the shield.

The waste water filter includes a shield including at least one inlet location for allowing the entry of unfiltered waste water into the shield. The shield further includes at least a first and second interior location. The waste water filter further comprises a filter element disposed within the shield, the filter element including at least first and second filter surfaces including filtering means that allow the passage of water while restricting the passage of solids. The first interior location of the shield is in direct fluid communication with the first filter surface of the filter element and the second interior location is in direct fluid communication with the second filter surface of the filter element.
