This is my setup:

 

It looks as if you already have an ejector system. Drain the washer into the slop sink. Totally code compliant.

 

I moved our laundry upstairs into the spot where the tub used to be in the master bath off the master bedroom (plumbing was already there and they fit like a glove 😎)

No more hauling clothes up and down stairs!

Cabinets over the w/d

Very quiet.

Free throws of clothes into the washer. Score! 😁

Find a way. It's worth it.

 

Also wondering if this is a bad idea for any other reason, i.e. pump breaks and floods the basement or something like that?

I'd rather have a washing machine potentially flood a basement than have it potentially flood an upstairs room.

And yeah, you just need to connect one of those laundry pumps. Basically a basin with a sump pump inside. $200 or so. Needing a sink before it may or may not be necessary depending on some things.

I suspect a pump made to directly drain the washer would need to be much larger than one to drain the sink. Having the sink gives the pump several minutes to pump the water out, where if it's direct from the washer, it would have to do it in about 30 seconds or less.

 

I just have the laundry pump, no sink. It's not a big basin, though the pump inside is a Zoeller, so it probably pumps fast. I think Zoellers are overrated, but that's another topic.

An inspector saw the setup in person and passed it. I know there's some codes that require a sink but would have to look it up. Thought it's just something about the drain pipe size.

If there isn't already a sink in the area, a person installing a laundry pump may as well put a sink in anyway since they can be useful.

I did that on my cattle farm. Before new washers, I realized I was dumping gallons and gallons of water into my septic tank that had nothing to do with septic, really. I piped the washing machine out to a hay field into perf pipe acting like a normal drain field. Oh, the boost that field got with the extra water.

The opposite happened here. A law/ordinance was passed that you could no longer send washing machine water out the regular sump pump into a ditch or similar. Had to connect it to the septic. So now instead of it being pumped out into a ditch for it to then drain into the ground, it gets pumped into an underground leach field for it to drain into the ground. ??

I put a large floor drain under the washer 🐻

 

Have you considered grey water management for the washer?

Face it. It is water, phosphate free detergent and a little lint.

A drain daylighted into a ditch, etc. could flow, unfiltered, into a creek or other waterway, while water percolating through a leach field gets filtered before it makes its way into any surface water drainage.
