I would like an answer to several questions.
1. I have a rough-in for a shower in my basement. The concrete floor has a 7" diameter hole with a cast iron pipe about 9" down from the concrete surface. There is a round plug in the end of the cast iron with no square in the center for a wrench. There appears to be lead
Around the outside of the plug. How do I remove the plug?
2. Once the plug is out, can I assume that there is a trap in place as part of the rough-in? The house is 40 yrs old.
3. What is the best way to tie in a PVC pipe to the cast iron? And do I need to back fill in around the drain pipe to support it. Like I said, 7" x 9" deep. I'm putting in a Swanstone base.
Thanks,
Dave
