No. This is a common mistake that leads to flooded basements. Downspouts handle a massive volume of water from your roof; if you dump that into a French drain, you will overwhelm the pipe and “back-fill” your foundation with water. At Basement Expert, we install a dual-system: a perforated pipe for groundwater and a separate, solid PVC pipe for your downspouts. This ensures that roof water is carried far away from the house without interfering with your foundation drainage.
