After having my septic tank pumped out last week I was told that my septic tank output baffle had fallen off. After doing a little research I figured I could handle this task of replacing it. I didn't video the process of gluing the PVC as I really just wanted to get'er done. Simply clean off the existing PVC pipe and glue on the PVC T that is the output baffle. The output baffle should extend down about half way to the bottom of the tank and is an essential for keeping your leach field and drainage system in good working order.
