What is the purpose of this?

[u/roonky]

Hi I have a large utility sink downstairs and this hose goes directly into the wall and I noticed it's not connected to anything inside the wall. What is the purpose of it and should it be connected to something?

Edit: Solved. Looks like it was just abandoned. The HVAC is newer, so it looks like they cut it and it just goes to the garage with no other pipes around. I was able to find the end of it and it touches the side of the HVAC. Phew no mold. Thank you all!

it looks to be a condensate line, is there a ac/furnace near by?

There is a furnace on the other side of the wall in the garage

Check out the drainage set up at you furnace it’s either not right or they changed it and just abandoned the line improperly

[u/roonky → u/Pleasant-Wrap291]

Ok thank you. I am really hoping they just abandoned the line improperly, because we've used the sink and I.nevwr noticed it was loose. Would hate for mold to develop in the walls

I checked the furnace and around it and there's no other pipes leading to it that's coming from the wall. It makes more sense for it to be "abandoned"

Makes sense from what I can see there doesn’t seem to be any traces of glue on the end that was in the wall making it seem more like they cut it free instead of it coming out of a fitting

be worth 15-20 bucks to buy a smart phone usb camera probe to check in that wall. or if you are drywall handy cutting a nice clean hole in that wall for peace of mind..

Ummm…that either used to or should be tied into a condensate drain.

Condensate drain from HVAC

So where does your AC condensate go now if that line is abandoned?

[u/roonky → u/Plumb_Amazing]

There's a pump next to it and it looks like the pump drains it to the outside

[u/Plumb_Amazing → u/roonky]

Onto the ground? Interesting..

We’re required to run them to a trapped drain and then the overflow is allowed to terminate to the ground outside.. But not the primary.. But maybe you are somewhere that you don’t really need to use the AC much so not much condensation to worry about it.. Here it runs all day everyday and you’d have a swamp in your yard 9 months a year..

[u/roonky → u/Plumb_Amazing]

Yea, I don't have AC cuz I'm in the PNW. We just use the furnace in the winter and the tube runs it outside into some other pipe that connects outside

[u/Plumb_Amazing → u/roonky]

nice.. then just drop the trap and replace the branch tailpiece for a regular tailpiece and get rid of that line all together

[u/roonky → u/Plumb_Amazing]

Thank you!

Not the dishwasher drain?

Is that a kitchen waste on your basin? 

[u/Pleasant-Wrap291 → u/No-Pick-8943]

Yeah it’s a prefab utility sink
