摘要： A pipe filter and closure assembly comprises a support member in the form of an annular collar or sleeve. In use the collar is positioned wholly within the pipe at some distance from an open (upper) end of the pipe. A filter element in the form of a strainer is releasably mountable to the collar so as to inhibit the passage of solid material through the pipe, whilst allowing the passage of fluids (liquids and gases) therethrough. A closure member in the form of a plug in use is mountable inside the collar to be seated at the strainer. In use when the plug is in place, the flow of material through the pipe is blocked. The location of the assembly or part thereof arrangeable wholly within the pipe reduces the ease of access to and presents significant difficulties for an operator seeking to tamper with the assembly.
