For most homes, you want a slow but steady drip in cold weather: usually about 1–2 drips per second, or just before the water turns into a thin stream.

How Fast Should Faucets Drip?

  • Aim for:
    • About 1 drip every 1–3 seconds for typical freezing weather.
* Up to 1–2 drips per second (a tiny trickle) in more extreme cold (around 0°F or below).
  • Visually, it should look like:
    • Not a solid stream.
    • More than a drip that pauses for several seconds between drops.

This slow movement of water helps prevent pipes from freezing while keeping water waste relatively low.

When To Drip Faucets

  • Start dripping when:
    • Temperatures are expected to be at or below 32°F for several hours, especially overnight.
* Many pros call out extra risk at 20°F or below, particularly for exposed or poorly insulated pipes.
  • Keep them dripping:
    • As long as the temperature stays at or below freezing or below the local “danger” threshold (often 20°F).

Indoor faucets farthest from the main supply or meter and those on exterior walls are usually the priority.

Practical Tips For Dripping

  • Use both hot and cold:
    • For two-handle faucets, slightly open both handles so each line is moving.
* For single-handle faucets, set the handle in the middle so both hot and cold side drip.
  • Other helpful steps:
    • Open cabinet doors under sinks on exterior walls to let warmer room air reach the pipes.
* Keep your home’s thermostat at 55°F or higher during a freeze, even overnight.

Water used for a small drip over a cold spell usually costs far less than repairing a burst pipe and water damage.
