Installation and setup,
guide by guide.

Most of what decides how an ice maker behaves for the next decade is settled on the day it is connected: the tubing behind it, where the shutoff valve taps into the pipe, the water pressure, how much slack is coiled behind the cabinet and whether the room it lives in ever gets cold. These guides are about that hidden setup, and about the times it matters again.

The Water Line Behind an Ice Maker: Tubing, Valve and Pressure

Copper, braided stainless and the plastic tubing makers warn about, saddle valves and local code, the pressure range, slack behind the unit and a five-minute check of a line you inherited.

First Ice After Installation: How Long, What to Throw Away, What to Check

Why a door or freezer ice maker needs most of a day, the batches and glassfuls that go down the sink, the sounds of a new unit and the setup details that keep the bin empty.

An Ice Maker in a Vacation Home: Closing Up and Opening Again

Switching off and closing the valve for a short absence, draining before a winter without heat, the undercounter and countertop shutdowns, reopening in order and leak sensors between visits.

Water lines, first ice and a unit left alone.

One explains the water line itself, from copper and braided stainless to the plastic tubing that manufacturers warn about. One walks through the first day after installation, when an empty bin is normal for hours on a door or freezer ice maker and the first batches go in the sink. The last covers a vacation home, where a line under pressure with nobody in the house and a winter without heat call for a proper shutdown.

None of them asks you to tap a pipe, cut copper or open an appliance's water system. They show what should be there, what to look at with a flashlight, and when the job belongs to a plumber or our technician. Figures come from GE, U-Line and other makers' installation instructions, printed beside the section they support.

Not sure where to start?

The short answerThe Water Line Behind an Ice Maker: Tubing, Valve and Pressure

A water line for an ice maker is a quarter-inch cold drinking-water supply with its own shutoff valve, run in copper, braided stainless or the maker's approved tubing, with a coil of slack so the unit can be pulled out.

The short answerFirst Ice After Installation: How Long, What to Throw Away, What to Check

First ice after installation takes 12 to 24 hours on a door or freezer ice maker, according to GE, because the mold must reach about 15°F before it fills.

The short answerAn Ice Maker in a Vacation Home: Closing Up and Opening Again

An ice maker in a vacation home should be turned off, with its water valve shut, whenever the house is left for more than a few days.

Questions about
installation and setup.

How long after installation should the first ice appear?
On a door or freezer ice maker, GE gives 12 to 24 hours. A countertop nugget unit starts within minutes. Either way, the first batches are thrown away to clear the new line.
What kind of tubing should feed an ice maker?
A quarter-inch cold drinking-water line in copper, braided stainless or the maker's own approved tubing, with its own shutoff valve and a coil of slack behind the unit. Makers warn against generic plastic tubing, which can crack with age.
What should I do with the ice maker when I close a second home for winter?
Empty the bin, switch the ice maker off and close its valve. If the house may freeze, the water inside has to be drained: undercounter units have a shutdown procedure in their manual, and a door or freezer ice maker should be drained by a technician.
