I've got a neighbor with a set up like that----It gets mighty cold here,too.

Look for a path to the drains---or consider a sump box with a pump and go overhead if your situation makes a gravity drain impractical.

Could be that was the original intention and the project ran out of money and/or it was forgotten about.

So it may have been designed this way? I thought washer drains always drained to the home sewer system. The overflow drain for the washer pan should go outside maybe? Could a backup be causing it to go out the wrong drain? Thanks.

It wasn't designed----it was a mistake--over site or or change of location.

That is a funky,make do set up---find a way to drain that properly and you will be much happier.

My neighbor closed in a porch and heated it (30 or 40 years ago--he's 90 something)

Then thought it would be nice to get the machines out of the house---he ran a temporary hose through the siding----decades ago.
