Drain for ice maker

Posted by rocks911 (My Page) on

I have a concrete foundation home in the Dallas area and want desperately to have an ice maker installed. As the wife and I have a lot of friends over during the summer the pitiful ice maker that our Samsung refrigerator just cant keep up.

We do not have an existing floor drain and an undercounter machine could be installed within 10' of our sink and refrigerator water line

Whats the best way to go about this?

Does anybody know of a dependable plumber in the Dallas area that could solve this for us?

Thanks in advance

They make built-ins with their own sump-pumps for these situations.

They also make manual-fill/manual-empty counter-top machines without drain.

Topic has been covered before. Suggest using search function here. Also suggest "plumbing" forum.


Ooops....this IS the plumbing forum....duh-me.

Should have said also search "appliance" forum.

Its all good, just weighing options, looking at alternatives.

RE: Drain for ice maker

An ice maker drain is required to discharge into an "Indirect waste receptor", which normally would be a floor drain however in this case there is no floor drain so we have to consider alternatives.

The first step is to determine approximately how much water the drain needs to handle.

Typically residential undercounter ice makers produce between 12 & 50lbs of ice per 24hrs.

Water weighs 8.34lbs/gal so 50lbs of ice would yeild 5.99gal of water.

Now assuming a worst case scenario where the ice maker would fail to operate and all the ice in the bin was to melt, it would no doubt take a minimum of 6 to 8hrs or more to melt so the anticipated load would be in the order of 1 or perhaps 2gph.

Zoeller, Grundfos, Little Giant and a number of other manufactures make small self contained pumps with receiver tanks that are marketed as HVAC condensate pumps, but if you check the specs they are also rated for commercial refrigerator drains & ice maker drains.

They are generally a very low profile so the pump and receiving tank can fit right under the icemaker bin drain line. You then run a small diameter plastic tube and discharge that into a sink, or into a dishwasher Wye tailpiece under a sink. The pumps operate on 115vac and they have a built in float swith to control the pump.

Run a search online for "Residential HVAC Condensate pumps" and you will see many listed.
