tapping into cleanout stack?

[jdmert]

I have a 4 " cleanout stack just outside the foundation. Can I, or is it not advisable to tap in another sewage pipe into that stack. I am trying to plan an area for my RV and I can get to 20 feet from the stack. I would just pump into it, but there are spousal regulations here that prevent that.

If I use 1/4 inch slope from the proposed site, the tap, using a 4x4x3 sanitary T, would connect to the stack at just about 4 inches above the main lateral line from the house. I would then continue the stack up and have the cleanout at the surface. (Which it wasn't but I got real lucky and dug in the correct spot 1st thing. )

If this is unadvisable, then I will have to start over completly in pplanning, but I would rather find out now before I create the pad for the RV and have to move it.



Thanks

I think your fine if I'm understanding you correctly. Draw a picture with az much detail as you can with what is attached where.

my artistic talents suck, but I hope it gives an idea. In the first picture you can see the coller for the y used to add the cleanout. the dirt covers the main lateral by about and inch in that picture. My predicted tap would glue so that it was almost touching that y which would make I estimate a 4-6 inch drop for waste from the rv site once it hits this stack.

You should be good. I do know there are sometimes local ordinances against this specifically.

Not if it is a double clean out in the ground.

She plumber is right. You need to make sure this fitting is directional pointing in the direction of flow.

It does flow correctly, and will not be disturbed. I am just a really poor artist.
