I have two drains on both sides of my driveway that are clogged with mud. they have been clogged for years. one, which is a catch basin, is clogged but still drains. It drains very slow. The other is not a catch basin and is clogged and does not drain at all. I rented a drain sewer yesterday from HD and ran it through both drains. I ran 75 feet through the catch basin drain and its still draining slow. the clog is under the concrete. I found this out because I replaced the 4 inch perforated pipe in the ground that was previously clogged and rerouted it. it's still draining slow. This lets me know that the clog is under the concrete. After running the automatic sewer snake through it yesterday, it goes all the way in but does not unclog anything. Why?????? Any reason???? For the second drain, I ran the sewer snake through it and cleared about 8-10 feet of the clog but there's about 25-50 feet of drain pipe under ground. How can I get these unclogged and draining correctly??? Is the only solution is to have them rerouted by a professional?
