Hello, me again....so I have replaced my old cast iron soil stack w/ PVC. The cast iron OD was 4 - 1/8" so I took Terry's advice and bought a Copper to Cast Mission Band. The problem that I am having is in order to get the PVC pipe that is inserted in the San-Tee below to fit under the 4" cast I had to cut the PVC pipe 1" short of the cast. My concern is that the mission band is only 2" wide. Therefore it is only grabbing the PVC pipe by a 1/2" and the cast iron by a 1/2".
This concerns me because I have pulled a permit and the city will put it under a 10' water test. I'm worried that this connection will leak because the mission band is not making enough surface contact.
The only solution that I see is cutting the PVC pipe approx. 2' below the cast iron connection and installing a coupler and a second mission band by cutting the PVC to length and then sliding the mission band down and then back up to make the connection. This idea really does not appeal to me. But I don't think that there is any other way to decrease the 1" space between the cast and PVC.
Any thoughts or other ideas are greatly appreciated. Thanks
