Ever seen this material?

I’m unfamiliar with this drain line material (looks like electrical conduit but with rubber interior lining). It did have a trap inside (the sink was in a garage).

Looks like hose I use for my fish pond pumps to my filters .

Looks like a swimming pool vacuum hose.


Ahh, that’s it. Thanks!

There’s a good reason that you have not seen it used in this application before.

That’s funny! Yep!:smiley:
