09 Oct Installing Rainwater Systems the Right Way: Key Tips for Professionals

When it comes to rainwater management, the correct installation of gutter systems is everything. A well-installed rainwater system not only enhances the performance of your roof drainage but also ensures long-term reliability and compliance with local standards. Whether you’re working on a new build or replacing an existing system, these essential installation guidelines will help you complete the job correctly the first time.

1. Get Your Tools Ready

Before starting, make sure you have all the necessary tools on hand to save time and ensure accuracy.

Typical tools required include:

• Hacksaw or cutting tool
• Measuring tape and level
• Drill and screwdriver
• File or pinchers (for notching)
• Brackets, clips, and fittings

Having your setup organised beforehand means fewer interruptions and a smoother workflow on site.

2. Follow Correct Fascia Bracket Spacing

Fascia bracket spacing should not exceed 1 metre. Proper bracket placement ensures the gutter remains stable under load, especially during heavy rainfall.

• Always check alignment with a level to maintain even fall towards the outlet.
• Secure brackets firmly to prevent sagging or joint strain over time.

3. Support Gutter Joints Correctly

When joining sections of gutter, make sure a fascia bracket is installed within 10 cm of each fitting. This provides essential support at connection points, reducing stress and preventing leaks or warping caused by water weight and expansion.

4. Allow for Expansion and Contraction

PVC rainwater systems expand and contract in response to temperature changes. Always allow sufficient movement at joints and fittings.

• Don’t glue gutter joints — instead, use jointing clips provided.
• Follow manufacturer guidelines for expansion gaps to maintain system integrity.

5. Fit Pipe Clips at the Right Points

Pipe clips should be fitted:

• On the downpipe shoe,
• Halfway up the downpipe, and
• At the top of the downpipe.

This secures the system against wind load and water flow, ensuring long-term stability and performance.

6. Cutting Gutters

When cutting gutter lengths:

• Secure the gutter on a flat surface.
• Use a fine-tooth saw or cutting tool.
• Always make a square cut for accurate joining.

Clean the edges of burrs or dust before assembly to achieve a watertight fit.

7. Notching Gutters (Vynadeep Systems Only)

For Vynadeep gutters, create a notch to overlap sections neatly:

• Make two small cuts approximately 35 mm apart.
• Remove the centre using a file or pinchers for a precise, clean finish.

This ensures a seamless joint that maintains proper water flow and prevents leakage.

Final Checks

Once installed, run a quick water test to confirm correct flow direction, alignment, and sealing. Address any drips or uneven areas immediately to avoid long-term issues.
