tie in to existing plumbing


I want to entend my 4" sewer line into my addition and want to tie in at the existing cleanout. A new cleanout will be placed at the end of the line. Will I have to remove the cleanout fitting and place a coupling or is there a fitting I can use to tie in to the cleanout? The line is PVC an this will be done in a crawl space with adequate space.

What is the distance of the new run? Is it a straight shot or is there going to be a bunch of offsets? I would replace the cleanout fitting with a new wye fitting to still maintain an active cleanout at this location if the existing line goes through the foundation wall right where you want to connect to. You want to make sure you have access to the underground pipe in case you need to snake it in the future.

The distance is 9 feet. That is where the location of the toilet will be and the end of the line extension.

Its not accepted practice to remove a CO plug and install a male adpt in order to extend the line. Typically you want to remove and relocate the cleanout or tie the new line in downstream of the existing CO then install another CO on the new branch line if its more then 5ft long. (based on local code)

I will remove the cleanout and use a coupling to extend the line. Thank you for the info.
