Why it matters
Prevents costly damageSkipping 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.
- Pull the fridge out far enough to see the line and the shutoff valve behind it.
- Run your fingers along the line and around both fittings, feeling for damp spots or mineral crust that signals a weep.
- Check the saddle valve or shutoff for corrosion and drips.
- 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
DIY to inspect. Replacing a valve is a comfortable-DIYer job; call a plumber if the shutoff is seized or corroded.
