🛠️ Materials & Tools Needed
- PVC pipe (3" or 4")
- Downspout adapter (flush-fit or flexible)
- PVC elbows and connectors
- PVC primer and cement
- Shovel or trenching tool
- Gravel (optional)
- Tape measure and level
- Hacksaw or PVC cutter
📐 Step-by-Step Installation
- Plan the Drainage Route: Choose a safe discharge point like a dry well or daylight outlet.
- Dig the Trench: 6–12" deep with a slope of
¼ inch per foot. Add gravel if desired. - Connect the Downspout: Use a flush-fit or flexible adapter for a watertight seal.
- Lay the PVC Pipe: Dry-fit, then glue joints with primer and cement. Use elbows as needed.
- Install Cleanouts (Optional): Add a vertical cleanout pipe near the downspout for maintenance.
- Secure the Outlet: Discharge to a safe area with a DrainBox or splash block.
- Backfill the Trench: Cover with soil or mulch and compact gently.
⚠️ Common Mistakes to Avoid
- Too little slope—causes pooling
- Improper adapter fit—leads to leaks
- No cleanout access—makes maintenance hard
- Using corrugated pipe—prone to clogs
