Abstract
Abstract A pipe baffle and installation assembly for a sewage tank is disclosed. The baffle comprises a corrugated polyethylene sheet having two circular ports which overlap when the sheet is folded prior to installation. The baffle is mounted on the interior of the sewage tank by positioning the overlapping ports over a sleeve housing the pipe, and is secured to the tank interior with an annular locknut that engages the sleeve. A method for installing the sleeve, the baffle and the locknut is described.
