Spears P110 Series PVC DWV Pipe Fitting, Flush Plug, 6 NPT Male

Perfect fit for the septic pipe. Now my lawn boy can mow over the cap.

Hard to find and it fits perfectly to 6 drain clean out.

Perfect Fit. thanks

After hitting the cleanout plug with the raised square on the top I ordered this one. Goes in to flush to the ground so that cant happen again.

Worked exactly write and fit perfectly.
