- Insert the first pipe section, securing it to the bracket with screws.
- Add elbows or connectors as the run requires, using a small bead of water resistant sealant on each joint.
- Continue adding pipe areas, examining the level after every two or 3 pieces to keep the correct slope.
- Protect each joint with the appropriate brackets-- normally one bracket every 1.2 m (4 feet) of straight run.
6. Connect to Drainage
If the downpipe feeds into a storm drain or a soakaway, attach the appropriate outlet fitting and seal the connection. Ensure the outlet is clear of particles.
7. Last Inspection
- Run water from the rain gutter (or utilize a garden hose pipe) to check the system.
