The drain line from our cast iron tub is lead and is brazed (?) to the large 90 that connects the toilet to the main stack. The tub drain has a dip in it and does not have a trap. I would like to replace the lead pipe with PVC but don't want to touch the tub drain- toilet 90 connection (the brazed part). Question #1: Can I cut the lead pipe at the braze and connect a new PVC line (to go to the tub) with a fernco?
Question #2: Do I make a P-trap with individual PVC fittings or can I buy a P-trap. My local home store has P-traps for sinks but nothing labelled specifically for tubs.
Sorry for the length-hope I explained the problems. Thanks
