Home - Waste Dump
I’m having my sewer clean out moved out from underneath our home. I want to be able to dump the RV in it. What size line should we use, 3” or 4”?

Code will dictate the proper size.
OP is using an existing clean out under the house and will be extending it outside. If the clean out pipe size is 3" you sure don't want to increase it to 4" and if it's 4" you sure don't want to decrease it to 3".
So as I said before whatever size it is that is the size pipe that needs to be used.
So let's say the existing clean out is 3" and current code says 4". What do you suggest the OP does then???
OP, extend what is there and be happy!
