Step-by-Step Installation Guide for Under-Sink Faucet Nuts

Installation begins by turning off water supply and draining residual water. Remove old mounting hardware, clean the under-sink surface, and position the faucet above the sink. Thread the under-sink nut onto the supply lines, tighten securely using a wrench, then connect hot and cold lines. Double-check all connections for tightness before restoring water flow to prevent future leaks.

Using plumber’s tape on threaded connections can improve sealing, while ensuring the nut is snug but not over-tightened prevents damage.
