Hello everyone,
I need to move the shower drain to be aligned with the new shower base. Reading from the internet, I think this is also good time to replace the cast iron P trap by PVC. Already break the concrete floor to reach the P trap. My question is where should I cut the pipe? In the photos below, what is the best position to cut? 1 or 2?
Few other questions if you don't mind:
1. I guess 2 and 4 is one piece?
2. How is the P trap connected to 4? By threading? Some say they could be soldered together but I can't figure out.
3. I seems the vertical drain pipe is connected to the P trap at position 5 using thread?
4. There is a big pipe (about 7 inches I guess) numbered 3 next to the drain pipe. I have no idea what is is. There is a gap and I can look inside it. There is a lot of soil inside so I guess it's unused or abandoned. It's not made from iron when I use a magnet to test. Do you know what it is?
5. The cast iron P trap still looks not so bad to me. Should I replace it by PVC anyway? My house was built in 1963.
Thank you so much for your help.
