I have a drain in my garage floor. I've never worried about it too much, but with some heavy rains recently I discovered it doesn't work.
It appears to be clogged with lots of dirt, pebbles, and leaves. I tried pouring a bunch of water down it to see if I could find the exit, but could not.
Would this drain go to the sewer? If not, what can I do to unclog it? How can I figure out where it goes?
I've taken a look at this question, but the drain is in the concrete, so digging it up is out of the question. Also, it appears -from jamming flexible tubbing into it- that it gets clogged almost right away, so I don't think snaking it will tell me anything.
Any help is appreciated.
