Thanks for reaching out! Sorry for the trouble w/ the pipes.
1. If you can find the room with the pool and the bed, exit to the North-West.
2. When you come to the first intersection, turn to the South-West.
3. Proceed to the end of that section and walk into the darkness to exit the sewers.
Let me know if this doesn't look familiar or you still can't find the way out and we can figure something else out.
Thanks for playing, hope you enjoy it!
