Do holes go up or down in a French drain?

Why do French drains fail?
This is the process by which small particles of clay and silt are stopped by the fabric and, over time, the fabric becomes stopped up and will no longer allow passage of water. When enough sand, clay or silt gets past the fabric, the gravel spaces fill and the effectiveness of the french drain ends.

Do French drains need an outlet?
A properly designed French drain system does not require an outlet. The water will simply soak into the soil as it flows along the perforated pipe. In fact, a French drain doesn’t require an inlet on just one end either. You can construct the drain to accept water along its length, and disperse it underground.
What size gravel is best for French drain?
For the best drainage, look for coarse washed rock (gravel) that is screened, with a stone size of 1/2 to 3/4 inch. Smaller rock with fine particles could clog the holes of the drain pipe. Pea stone works, but the smooth stones settle together and don’t move as much water as coarse rock.
Do French drains cause mold?
Moisture and mold: The soil surrounding the pipes and gravel installed under the concrete is always wet. Wet soil will grow mold. The mold spores, odor and evaporating moisture will travel into the house through the opening in the french drain system.
How do I know if my French drain is working?
