ABS to Cast Iron Coupling Under Slab

spafrica2003March 25, 2014

I am looking to install a basement bathroom. I believe I have 4" Cast Iron waste pipe under the slab. I will need to tie the toilet and shower into the horizontal waste line under the slab. I have been told that the Fernco-type couplings with the metal bands are not acceptable if they are in the ground as they will eventually corrode. Can anyone tell me what product is out there to tie new ABS onto existing cast iron when under ground? If possible, can you post a link to where they can be purchased?

" I have been told that the Fernco-type couplings with the metal bands are not acceptable if they are in the ground as they will eventually corrode."
Who told you that? And if someone here tells you the opposite, then you will be in the difficult position of choosing which to believe.

"help maintain proper alignment even the most unstable ground conditions"

Here is a link that might be useful: Look here
