Septic system vent screen

Abstract

A mosquito screen attachment denies access to mosquitoes from entering a vent pipe connected to a subterranean septic or other fluid filled tank. It includes a pipe joint section with mosquito screen pre-attached to the one or more vertical open faces of the horizontal portion. The lower opening on the vertical downpipe is simply attached atop the open vent pipe. Preferably the pipe joint is made of PVC which is also the typical material of the vent pipe. A rigid PVC mosquito screening is used, which is bonded or sealed to the edges of the one or more exposed holes of the pipe joint section. A robust material as opposed to a softer fabric screen is preferable to keep out bats or the beaks of birds attracted to hovering mosquitoes near the openings. The vertical orientation of the two vent holes helps keep debris from accumulating to clog the screened openings.

1 . A mosquito screen attachment which denies access to mosquitoes from entering a vent pipe connected to a subterranean septic or other fluid filled tank comprising:
 at least one pipe joint section having at least one sideways oriented, vertically extending open face of a horizontally extending pipe portion, said sideways oriented, vertically extending open face having at least one mosquito screen attached thereto,   said at least one mosquito screen covering said sideways oriented, vertically extending open face to prevent mosquitoes from entering said at least one pipe joint section, wherein said at least one sideways oriented, vertically extending open face is screened in, and,   said at least one pipe joint section having a covered top roof portion to keep falling particulate debris, rain or snow from entering from above;   said at least one pipe joint section having a lower opening on a vertical downpipe section attached atop the open vent pipe connected to the subterranean septic or other fluid filled tank.   
     
     
         2 . The mosquito screen attachment as in  claim 1  wherein said at least one pipe joint section is a pipe T joint with a horizontal section and a vertical downpipe attached to said open end of said vent pipe connected to the subterranean septic or other fluid filled tank. 
     
     
         3 . The mosquito screen attachment as in  claim 1  wherein said at least one pipe joint section includes a horizontally oriented L-shaped joint with two horizontally extending sections and a vertical downpipe attached to the open end of the vent pipe connected to the subterranean septic or other fluid filled tank. 
     
     
         4 . The mosquito screen attachment as in  claim 1  wherein said at least one pipe joint section comprises a vertically oriented J-shaped pipe joint with one horizontal section and a vertical downpipe attached to the open end of said vent pipe connected to the subterranean septic or other fluid filled tank. 
     
     
         5 . The mosquito screen attachment as in  claim 1  wherein said at least one pipe joint section is a multi-joint X-shaped pipe joint with four horizontal section and a vertical downpipe attached to the open end of the vent pipe connected to the subterranean septic or other fluid filled tank. 
     
     
         6 . The mosquito screen attachment as in  claim 1  wherein said pipe joint is made of polyvinyl chloride PVC piping material. 
     
     
         7 . The mosquito screen attachment as in  claim 6  wherein said PVC piping section is injection molded. 
     
     
         8 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is attached to said pipe joint section by PVC cement. 
     
     
         9 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is attached to said pipe joint section by an adhesive sealant. 
     
     
         10 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is bonded to respective edges of said at least one hole of said pipe joint section. 
     
     
         11 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is attached to said at least one pipe section by glue. 
     
     
         12 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is a robust metal screen. 
     
     
         13 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is a robust plastic screen. 
     
     
         14 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is molded together with said at least one pipe joint section. 
     
     
         15 . The mosquito screen attachment as in  claim 6  wherein said mosquito screen is attached to said at least one pipe joint section by mechanical attachments. 
     
     
         16 . The mosquito screen attachment as in  claim 1  wherein said at least one pipe joint section is a plurality of pipe joint sections, each with a respective sideways oriented, vertically extending open face covered by said at least one respective mosquito screen.
