Wow! I've never seen someone route a "temporary line" of something through the pool AND shoot gunite around it! Can you give us more specifics about this process? How is this going to affect plaster? What are the two pipes coming up from the floor? Are they just to hold up the big pipe? Looks great otherwise!
Glad you're making progress again.
Will you have to live with those sewer cleanout caps that close to your pool, or will you be able to bury them somehow?
