Installing a French drain can prevent water damage, but there are common mistakes to avoid for effective drainage.

**Poor Site Selection:** Choosing a location with high water tables can render your French drain ineffective.
**Incorrect Slope:** A slope of at least 1% is vital for proper water flow.
**Insufficient Gravel:** Not using enough gravel can clog the drain with silt and debris.
**Ignoring Local Drainage Laws:** Failing to adhere to local regulations may result in fines.
**Inadequate Outlet:** An outlet that is too close to the foundation may cause water pooling.
**Neglecting Maintenance:** Regular upkeep is essential to keep the drain functioning.
**Using Non-Perforated Pipe:** Non-perforated pipe limits water absorption from surrounding soil.
