Basement drain keeps leaking water into our basement
We have lived in our house for over a year and have no problems with plumbing until this week. One of our basement drains keeps over flowing. Nothing is running. Like a dishwasher,washer, etc.) I noticed it during a heavy rain day but it has not rained in two days but more water keeps pouring out of the drain. We tried plunging it, using draino and it doesn't seem to help. It is coming up (slower now) and every day we are sucking up the water with a wet/dry shop vac. Any one know what to do? Any ideas what this is and how to fix it? Thanks!!
I thought I should also give a little more info. The house is from the 50s, the water coming up has no smell, is clear but looks like dirt or black stuff is also coming up.
