I don't think the hub size is standardized on clay pipe, I think you need to measure and find the right doughnut. You can also pack it with oakum and pour and pack lead or oakum and pack it with lead wool or probably oakum and mortar. Make sure you dry out the hub with the torch before you pour the led, if it is wet the steam will cause bad things to happen. You can find a transition fernco that fits over the outside of the hub and over the PVC and put it over the packed joint as a secondary seal. Could pour it all in concrete after you do it too so if the joint fails it is still all essentially contained in a formed in place concrete pipe.

Hi, How about putting a big hose clamp around the pipe, snugging it up a bit, and then cramming the Fernco into it? 🤠 That's what I do when making any threaded connection to a plastic female adapter.

I misunderstood your comment.

My mistake.

That is a lot of weight on the pipes. An accident waiting to happen. I never like to see the copper pipes take the weight of an expansion tank, waterlogged or not.

Install something like this with the new tank, or even the current one if it only needs air.

These two items work great when installing an expansion tank and bear all of the weight.

@delcrossv Fernco calls it a "Multi Tite" I call it a soil pipe push gasket. Here's a few examples.

Duh. Fernco donuts
