Full details

The Wavin Osma SquareLine 90° Gutter Angle (4T803W) provides a clean, square-line aesthetic while ensuring efficient water management around corners.

Extended Product Information

FAQs

What is the maximum roof area this angle fitting can support?

The Wavin Osma SquareLine system, including this 90° angle, is suitable for a maximum roof area of 178m² when using one downpipe.

Can this angle be used for angles other than 90 degrees?

No, this fitting is specifically designed for 90° turns. For other angles, you would need to use different fittings like offset bends or flexible connectors from the Osma SquareLine range.

What color options are available for the SquareLine system?

The Osma SquareLine range is available in black, white, and brown.

How do I ensure a watertight seal?

The fitting features a retained seal. Ensure the gutter ends are pushed firmly into the seals within the angle fitting until the Flexiclip mechanism engages, creating a secure, watertight joint.

What size downpipe does this system use?

This 100mm SquareLine gutter system is designed to connect with a 61mm square downpipe.

How should I clean the gutter angle?

Clean the gutter angle using a damp cloth and mild soap if necessary. Avoid harsh chemicals or abrasive materials that could damage the finish or the seal.

Are replacement seals available?

Yes, replacement rubber seals for the 100mm SquareLine system are available, often in packs of 5 or 10 (e.g., Osma MPN 4T864).

Troubleshooting

Leaking joints

Ensure the retained seals are properly seated and that the gutter sections are fully inserted into the angle fitting. Check for debris within the seal. If seals are damaged, replace them with Osma Squareline Replacement Rubber Seals (4T864).

Gutter does not fit securely

Verify that you are using the correct 100mm SquareLine gutter and 61mm SquareLine pipe components. Ensure the Flexiclip mechanism is engaged correctly. Check for obstructions within the fitting.

Angle does not align correctly

Confirm that the correct 90° angle fitting is being used. Ensure the gutter runs leading into the fitting are straight and correctly positioned.

Reduced water flow

Clear any blockages in the gutter, angle fitting, or downpipe. Ensure the system has a continuous, slight fall towards the downpipe.

Pros and Cons

Pros

Provides a clean, modern square-line finish.
Ensures a watertight connection at corners with its retained seal.
Easy installation thanks to the Flexiclip mechanism.
Designed for efficient water flow around 90° bends.
Durable construction for longevity.

Cons

Limited to 90° turns; requires additional fittings for other angles.
Only suitable for roof areas up to 178m² per downpipe.
Requires 61mm square downpipes, limiting compatibility with round systems.
May require specific tools or techniques for optimal seal compression.
White color may be prone to discoloration over time if exposed to harsh UV.

Setup, Compatibility & Care

Setup:

Ensure the existing gutter runs are clean and free of debris.
Apply a small amount of silicone lubricant to the seals of the gutter sections and the angle fitting for easier insertion.
Slide the gutter ends firmly into the retained seals of the 90° angle fitting until they click into place with the Flexiclip mechanism.
Ensure the angle is correctly oriented to direct water towards the downpipe.

Compatibility:

This fitting is part of the Wavin Osma 100mm SquareLine gutter system.
It is designed to connect with 100mm SquareLine gutter lengths.
It connects to 61mm SquareLine downpipes.
Ensure all components are from the Osma SquareLine range for a proper fit and performance.

Care:

Regularly inspect the gutter system for blockages, such as leaves or debris, and clear them promptly.
Periodically check the seals and joints for any signs of wear or leakage.
Clean the gutter and fittings with mild soap and water. Avoid abrasive cleaners or solvents, which can damage the material.
