Can a Fernco fitting be left….

NietzschesMustache | Posted in General Discussion on July 7, 2009 06:18am

…behind the drywall, in the ceiling? I have to transition from 1 1/2″ PVC to 1 1/2″ galvanized drain pipe.

If not, how do I get the piece of galvanized unstuck from the 4″ cast iron so I can attach the PVC directly? The galvanized is in bad enough shape that it might break.

      Thanks, but can't do it. I have about 8" of horizontal pipe left, and I can't get to the vertical stack.

            lube the donut on insde, chamfer the end of the squarely cut PVC a tad... push the PVC stub into the donut using a scissors jack from yur car... use a repair coupling off of the stub to go where ya need to...

            So we are looking up at the cieling in this picture? Just to be clear.

            That is a cieling joist with 1x4? subflooring on top of it.

    Yes, you can do that where I live. You have to use what the plumbers call a "mission" coupling (which I think is a brand). The metal band is crinkled so it doesn't buckle when the hose clamps are tightened. http://www.missionrubber.com/Products/NoHubCouplings.php

    That is a screw joint, you should be able to unscrew it with a pipe wrench, put in a male pvc adapter, short piece of pvc and a glued cap, should be easy, luck.

    No doubt the galv won't back out, right?

    Cut it close to the CI, then score the inside with a sawsall...slowly, and not on the bottom where it's 'wet'

    Knock it out with a cold chisel. Insert PVC transition, with dope and tape.

      Thanks, everyone. Done got it did. I used the edge of a half-round file to get the remaining pipe loose, much as betterbuiltnyc recommended (couldn't get the RS up there between the joists).

      If warming the cast and applying a pipe wrench to the galv. didn't bring it out.

      That would be the next step.

      I reccomend a fine tooth blade and sawsall with slow variable speed.

      And lots of patience.

      Good luck
