Simplified sink plumbing. Trap style, valve location, connections and venting vary; venting is not shown.
1. Aerator
The small outlet fitting shapes the faucet stream. Some aerators unscrew externally; others need a matching recessed key.
Size and thread pattern matter. A faucet brand alone does not identify the correct replacement.

Nuts or brackets hold the faucet to the sink or counter. Access underneath can be tight.
A basin wrench or mounting tool must fit the actual hardware and available space.

Local shutoff valves feed hot and cold water through supply connectors.

Match the pipe connection and faucet supply outlet.
View on Amazon ↗4. Slip-joint seal
Many tubular drain connections use a nut to compress a correctly sized washer around the tube.
The washer makes the seal. Adding thread tape is not a substitute for the correct parts and alignment.

For matching tubular slip joints; confirm washer profile.
View on Amazon ↗5. P-trap
The curved drain holds a water seal that helps keep sewer gases out of the room.
Clogs, loose connections and a lost water seal cause different symptoms. A persistent problem needs diagnosis.
