How often should you inspect your ice maker water supply line?

Quick answer: Once a year. A pinhole leak behind the fridge silently rots flooring for months.

Why it matters

Prevents costly damage

Skipping it eventually leads to water damage or an expensive repair.

Staying on schedule matters beyond the repair bill: a consistent maintenance record is one of the factors in a home's Roots Home Health Score, and well-kept homes typically sell faster and closer to asking price.

How to do it

A thin plastic or copper line feeds water to the ice maker. A slow leak behind the fridge can go unseen for months while it rots the flooring and subfloor underneath.

  1. Pull the fridge out far enough to see the line and the shutoff valve behind it.
  2. Run your fingers along the line and around both fittings, feeling for damp spots or mineral crust that signals a weep.
  3. Check the saddle valve or shutoff for corrosion and drips.
  4. If anything is damp, shut the water off and replace the line before pushing the fridge back.

Alternatives & optional extras

  • Old-style saddle valves are leak-prone; upgrading to a proper quarter-turn valve during a kitchen project is worth it.
  • A braided stainless line resists kinks and bursts better than the thin poly tubing most ice makers ship with.

Time: 15 minutes · Typical cost: Free to inspect; $10–$25 for a replacement line
