How We Chose the Best Undercounter Ice Maker With Drain Pump
To choose the best undercounter ice maker with drain pump, we compared undercounter and commercial ice makers sold on Amazon in the U.S. on listed daily output, bin size, width and height, drain type (gravity or pump), venting, ice type and cleaning features, using each listing and the maker’s information. We read owner feedback for recurring problems such as leaks, slow output, noise and drain issues. We did not run our own lab tests, so output figures are maker claims.
We checked efficiency claims against ENERGY STAR refrigerator guidance and food-safety temperatures against the FDA’s food storage advice (40°F or colder in the fridge, 0°F in the freezer). Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
How to Choose the Best Undercounter Ice Maker With Drain Pump
How a drain pump works
A small pump collects melt water and pushes it through a tube up to a sink drain or standpipe, so the machine does not need a floor drain.
Confirm the drain on each listing
Not every undercounter machine includes a pump. Check the listing, and add the maker’s pump kit if needed.
Measure the opening
Standard undercounter openings are about 15 inches wide and 34 to 34.5 inches tall. Many commercial machines are wider or taller, so measure before you order.
Gravity drain or drain pump
A gravity drain needs a floor drain or standpipe below the machine. Without one, choose a model with a drain pump that pushes melt water up to a sink drain.
Front venting for built-ins
Built-in machines must breathe through the front grille. Freestanding-only models can overheat when boxed into cabinets.
Water line
Undercounter ice makers connect to a cold water line, usually 1/4 inch. A shutoff valve behind or beside the machine makes service easier.
Daily output is a maximum
Listed pounds per day assume ideal room and water temperatures. Hot rooms and warm water cut production, so treat the number as a best case.
Bin size versus output
Output tells you how fast ice is made; the bin tells you how much is ready at once. Busy bars want both, homes care more about a steady bin.
Tips for Installing an Undercounter Ice Maker
- Measure width and height Most openings are 15 x 34 in.
- Plan the drain Gravity drain or pump.
- Add a water filter Less scale.
- Clean every six months Keeps ice fresh.
