The 4 in. PVC Sanitary Tee adds a 90° sweep to a 4 in. sewer and drain SD pipe run. The San Tee, or Sweep Tee, is installed for less turbulent flow and easier clean out of the pipeline. The San Tee connects three lengths of pipe, and also connects to select drainage products such as channel drain outlets, Flo-Well Dry Well System, drainage grates, and pop-up emitters. This tee is used to add an intersection to the pipeline, connecting three pipes of the same type and diameter size. The drain fitting is made of polyvinyl chloride PVC for Hub X Hub X Hub solvent-weld connections. Meets applicable ASTM standards. For use in non-pressurized underground sewer and drainage applications; maximum working pressure of 5 psi.
