OK, it's time to rebuild. I've purchased the 3" donut, but it does not appear that it will create a water-tight seal between itself and the hub, even after I slide the 1.5" PVC pipe into the donut. My concern is without a water tight seal, this upstairs bathroom sink drain will leak past the donut. There is a tight fit between the 1.5" PVC pipe and the inside diameter of the donut and I don't believe that water will leak from there. After measuring this hub, unfortunately it's not an issue of extra heavy duty vs service weight hub construction. I have a non-standard, 3.25" diameter hub and I've not been successful in finding, a company, including Fernco, to make a one-off donut gasket. I'm now looking for ideas and working on Plans-B-C-D etc. since I don't want to tear-up this floor ever again to access this connection. I live in Cleveland, OH. And these are my thoughts:
1) Sawing off the hub and using a "saddle" is not allowed by code and I don't have the room.
2) The surface of the hub is not smooth enough to secure a water-tight connection if I were to try and use a "boot" to fit over the hub opening and clamp down on the exterior surface of the hub.
3) Although I can't determine if the Code allows re-leading this joint, I'm considering using the old style method of oakum, but substituting "Harvey's Soil Seal" compound, instead of using lead to re-connect this joint. Has anyone out there had any experience using this "Soil Seal" product? It comes better recommended than using "plumbers epoxy".
Thanks!

Hi Rob...

Yup! You have the wrong DONUT there.. for sure. Have you checked with your local PLUMBING SUPPLY HOUSE?

The Harvey's soil seal will also work here but you will need to use a MANHOFF fitting (see picture) to meet code requirements. This manhoff fitting is available only at a PLUMBING SUPPLY HOUSE.. ok? Bring this picture with you IN CASE they try to call it something else and tell you they don't have a manhoff.. ;)

Purchase the correct donut OR get some oakum and a 3" PVC manhoff fitting and then install the manhoff fitting into the cast iron hub and pack oakum in until you have about 1" to 1.5" depth left to fill with the lead substitute. Then follow directions on the can to pack the lead substitute into place. Let dry per instructions. Then reduce out of the 3" manhoff as needed with a 3"x1.5" PVC bushing to pick up the sink upstairs. All this should be very legal.. in your area and mine.

Finally, leading a joint in is also acceptable by code, but lead substitute should do this for you.

Let me know if you have questions...

Again a very good answer, and the pictures makes it even better.
