Hey Folks,
I was just watching a Youtube video from a respected plumber and he mentioned in passing that you are only allowed one ABS to PVC connection in a residential plumbing system. When I read the OBC it does not specifically say this based on my interpretation. Not sure why only one would be allowed other than maybe the thinking is the entire house portion would be lets say ABS and the sewer connection might be PVC. I'm in the process of building a house on piers. The main drain is currently 4" PVC and runs the length of the house (35') just below the floor joists adjacent the central support beam. All the branch runs are 2" and 3"ABS connected to the PVC with primer and transition cement. There are 7 branches.
Does any body know if this is OK? Is there a limit?
I'm using ABS inside because water flow is more muted due to it's thicker walls and I find ABS easier to work with. I'm running 4"PVC outside because it's much less expensive than 4" ABS, it's thinner and therefore can be enclosed in a smaller chase and heat transfer is easier (the chase will be insulated and heated)
