Attached is a diagram showing what I believe may be the arrangement of pipes & drain tiles in our house storm drain. I am pretty certain of the locations & connections of the storm drain, the cleanout & the drain to the municipal sewer. Maybe some one can tell me how the drain tiles are usually connected to the storm drain. It was built in 1965 so the drain pipes are iron & the drain tiles would be vitreous. The basement here is only under about 1/3 of the house - so there are two sides (attached garage & a great room adjacent to the other basement walls) which probably don't have drain tiles.
As indicated on the diagram, I have tree roots & some deposited sand which accumalate in the house cleanout. If left unattended, they ball up in the cleanout & eventually block the discharge of ground water to the municipal storm sewer. This, of course, results in water backing up at the floor drain & floods the basement.
Although I can clear the roots at the cleanout, this is just a short term fix. Longer term, I'm concerned that the roots may eventually block the drain tiles as well as the floor drain. This could lead to breaking up the basement floor, digging, etc., to replace the clogged pipes.
Is there any way that this condition can be serviced now to prevent; or delay this? Help from the experts will be very much appreciated.
