    Connecting PVC Line to Cast Iron pipe
    I am adding a second bathroom to an older 1-1/2 story house. I had planned to tie into the existing waste line. The existing toilet is on the first floor and discharges directly into a vertical cast iron pipe which appears to be 6 inches in diameter. This vertical pipe connects in the crawl space to the hub of a cast iron fitting which has two 1-1/2 inch diameter connections just below the hub for the tub and the sink. The line then goes into the crawl space ground and out to the septic tank. There are no cleanouts on the line in the crawl space which has about 30 inches of space between the floor and the ground. The vent pipe extends vertically on the OUTSIDE of the end wall of the house to a point just below the roof.

    Is there a practical way to tie a new PVC lines into the cast iron pipe in the crawl space, or would it be better to add a completely new PVC line to the septic tank for the new bathroom?

    Fernco makes just the coupling you are looking for my friend
    http://www.fernco.com/coupling.asp
    That should help you avoid replacing most of that old hub and spigot cast iron

    Just to add, you can pick these up at any plumbing supply store or home depot... so there's no need to order off the site

    Hi Joe,
    Big Kill gave you one option. Let me give you another. I prefer the metal bands called Fernco Shielded Couplings for the simple reason that the bands give the connection a rigidity that Fernco Neoprene Couplings never could. I have run the entire drainage systems on high raise condos using shielded couplings I couldn't have done it with Fernco Neoprene Couplings. Tom

    To be honest most of what I've used are no-hub bands (or mj bands as everyone calls them up here), they are a better solution absolutely... just spaced out and didn't know how to describe them
