We drained a couple of inches of water in advance of the storms this week. I ran a hose to the cleanout in the front yard near the sidewalk (City says to drain to sanitary sewer).
I noticed there is another cleanout just a few feet away from the foundation also in the front yard.
I'm assuming they're both connected (you can hear water running as I was running the pump) and that one is the "city" cleanout and the other is my "residential" cleanout. Not sure of the proper terms....
Is there a difference as to which one I drain to? We picked the city one because it was further away and less apt to get water backing up into the house.
