Do Fridges With Ice Makers Need To Be Plumbed In?

If you’ve ever dreamed of grabbing a handful of fresh ice cubes without refilling trays or dealing with freezer burn, a fridge with an ice maker sounds perfect. But before you buy, you might be wondering: do fridges with ice makers need to be plumbed in? The short answer? It depends. Some do, some don’t—and knowing the difference can save you time, money, and a plumbing headache. Let’s break it all down so you can choose the right option for your kitchen.

What Does “Plumbed In” Mean for a Fridge?

“Plumbed in” means your refrigerator is connected directly to your home’s water supply line—usually via a small copper or flexible plastic tube running from a nearby cold water pipe to the back of the fridge. This setup allows the ice maker (and often a water dispenser) to draw water automatically, eliminating the need for manual refills.

According to the U.S. Department of Energy, over 70% of American households with refrigerators made in the last decade include built-in ice makers—many of which are plumbed models. But not all require this setup.

Do All Fridges With Ice Makers Need Plumbing?

No—not all fridges with ice makers need to be plumbed in. There are two main types:

1. Plumbed (Built-In) Ice Makers

• Connected directly to your home’s water line.
• Automatically refill water for continuous ice production.
• Common in French door and side-by-side refrigerators.
• Ideal for high-usage households or entertainers.

2. Non-Plumbed (Manual Fill) Ice Makers

• Have a built-in water reservoir you fill by hand.
• Produce ice in batches (typically 6–12 lbs per day).
• Found in some counter-depth, compact, or freestanding models.
• Great for apartments, rentals, or homes without easy plumbing access.

💡 Pro Tip: Brands like LG, Samsung, and GE offer both plumbed and non-plumbed options. Always check the product specs before purchasing.

Pros and Cons: Plumbed vs. Non-Plumbed Ice Makers

For most homeowners with permanent kitchens, a plumbed model offers long-term convenience. But if you rent, live in a condo, or lack nearby plumbing, a non-plumbed unit is a smart, flexible alternative.

How to Tell If Your Fridge Needs Plumbing

Check these signs:

✅ Water dispenser on the door? → Almost always requires plumbing.
✅ “Ice & Water” label on the front? → Likely plumbed.
✅ No visible water tank inside? → Probably connected to a line.
✅ Owner’s manual mentions “water line connection”? → Confirmed.

Still unsure? Look behind the fridge. If you see a thin tube (¼-inch diameter) leading to a shut-off valve on a nearby pipe—it’s plumbed.

Installing a Plumbed Ice Maker: Step-by-Step Guide

If you’re adding a plumbed fridge to a kitchen without existing lines, here’s what to expect:

1. Locate Cold Water Supply
   Find the nearest cold water pipe under the sink or behind the wall (typically ½-inch copper or PEX).
2. Install a Saddle Valve or T-Fitting
   Use a ¼-inch compression T-fitting (not a piercing saddle valve—it’s outdated and prone to leaks).
   Recommended tool: SharkBite push-to-connect fittings (no soldering needed).
3. Run Tubing to Fridge
   Use ¼-inch flexible braided stainless steel or plastic tubing (max 25 ft length for optimal pressure).
   Route it through cabinets or baseboards—avoid sharp bends.
4. Connect to Fridge Inlet
   Attach the tube to the fridge’s water inlet (usually labeled “Water” on the back).
5. Flush the Line & Install Filter
   Run 2–3 gallons of water through the dispenser to clear debris.
   Install the manufacturer’s water filter (e.g., GE RPWFE, Samsung HAF-CIN) for clean ice.

⚠️ Warning: DIY plumbing mistakes cause 22% of fridge water leaks (per HomeAdvisor). If unsure, hire a licensed plumber.

Maintenance Tips for Ice Makers (Plumbed or Not)

• Replace water filters every 6 months—dirty filters cause slow ice production and odd tastes.
• Clean the ice bin monthly with warm, soapy water to prevent mold or odors.
• Check for leaks behind the fridge quarterly—look for puddles or dampness.
• Descale reservoirs (non-plumbed models) every 3 months using a 1:1 vinegar-water solution.

FAQ Section

Q1: Can I add an ice maker to a fridge that doesn’t have one?

A: Yes—but only if the fridge is designed for it. Some models have “ice maker ready” kits (e.g., Whirlpool W10884897). Retrofitting a non-compatible fridge is not recommended.

Q2: How much water does a plumbed fridge use per day?

A: On average, 3–5 gallons per day—mostly for ice making and dispensing. ENERGY STAR-certified models are more efficient.

Q3: What if I don’t have a water line near my fridge?

A: You have three options:

1. Run a new line (best for permanent homes),
2. Choose a non-plumbed model, or
3. Use a water line extension kit (up to 25 ft).

Q4: Do non-plumbed ice makers make ice as fast?

A: Slightly slower. They produce ice in cycles (e.g., 8–12 cubes every 2–3 hours), while plumbed models can make ice continuously.

Q5: Can I disconnect a plumbed fridge and move it?

A: Yes—but you must turn off the water valve, disconnect the line, and drain residual water to avoid leaks. Cap the valve afterward.

Q6: Is a water filter necessary for plumbed fridges?

A: Yes. Most manufacturers require it to maintain warranty coverage. Filters remove chlorine, sediment, and contaminants that affect taste and damage internal valves.

Conclusion

So, do fridges with ice makers need to be plumbed in? Not always—but if you want endless ice with zero effort, plumbing is worth the setup. Non-plumbed models offer flexibility and simplicity, especially for renters or small spaces. Either way, understanding your needs and kitchen layout is key to choosing the right system.
