How to Install a Perforated Sewer Drain Pipe

How to Install a Perforated Sewer Drain Pipe

Your septic system is comprised of pipes leading from your home to your septic tank, solid piping leading from your tank to a field bed and a perforated sewer drain pipe for drainage. Since improper placement of this pipe can cause sewer backup or clogs, knowing how to install one properly before undertaking this project is very important.

First, if you're working on a new installation, this job is best left to a professional. New septic systems must be approved by a permit in Broken Arrow and the surrounding areas before beginning. Grading and drainage requirements are quite stringent and a plan must be submitted for approval. If you're simply replacing an existing pipe, you should be fine as long as the problem you're having is due to the pipe itself.

You should use a four-inch pipe made of rigid PVC that has appropriate drainage holes. Never use corrugated flexible piping as these can't be cleaned without damaging the pipe. Once you've dug down to the original pipe, remove it carefully. Ensure there's a layer of gravel still in place for proper drainage. If necessary, add enough gravel to level the pipe with the system piping (usually six to 12 inches deep. Then, clean the main pipe thoroughly and allow it to dry.

With the majority of holes facing down, place your sections of perforated sewer drain pipe where they'll be installed. Using PVC primer and glue, glue the individual sections together. Use a level to make sure the pipe is in line, and then attach it to the non-perforated drain pipe on the tank. Next, cover the pipe with another six inches of gravel and a barrier to prevent the finishing soil from going into your gravel.
