Donut Into Hub Leak-Back Concern - Rebuild
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!
