Reconnect Water Supply and Test

What happens here

Once the toilet bowl and tank are securely installed and all bolts are hand-tight, reconnect the flexible water supply line to the fill valve on the underside of the toilet tank. Ensure the connection is hand-tight to prevent leaks. Finally, slowly turn the water supply valve back on, checking for any leaks around the water supply line, tank-to-bowl connection, and the base of the toilet.

Goal: Restore water supply and confirm no leaks
