Thank you for your responses. AC pipe is an asbestos cement pipe, just like cvg states. The attempted connection is a tee. The existing pipe is the 3" AC pipe; how would you connect an 8" pipe to it? It is a pressurized system by a 120' tall tank.
Thank you,

Is it possible to connect an 8" HDPE or PVC water pipe into a 3" AC water pipe? What pieces or couplings would be needed? What are possible restrictions and/or regulations?
Thank you,
