The Wavin Osma DeepLine 90-degree gutter angle is an essential component for homeowners and contractors installing or repairing high-capacity 113mm domestic rainwater systems. Its primary benefit is the inclusion of the advanced Flexiclip seal jointing mechanism, which guarantees a watertight connection at corner joints; however, users should note that this specific component is precision-engineered for the DeepLine profile and may not be compatible with standard-profile guttering systems.

No, this fitting is specifically designed for the 113mm DeepLine semi-elliptical profile and will not provide a secure fit on standard half-round systems.
Yes, it features a retained seal system that is factory-fitted for easier installation.
It conforms to BS EN 607:2004 standards for rainwater systems.
No, this specific product is fixed at a 90-degree angle and cannot be adjusted for other corner degrees.
Yes, the Osma DeepLine system is manufactured from durable PVC-u, designed to withstand standard outdoor weather conditions and UV exposure.
Check that the gutter is pushed fully home against the internal stop and that the seal is not pinched or displaced.
Verify the gutter end is deburred and square; apply a small amount of silicone lubricant to the seal if friction is too high.
Installation should begin by cleaning the gutter ends of any debris or lubricants. Because this fitting uses a retained seal, do not apply excessive force when clicking the gutter into the Flexiclip mechanism. Ensure the gutter is cut squarely to provide an even surface against the internal stop. Regarding care, the system is low-maintenance; however, it is recommended to inspect the joints annually after autumn to clear any accumulated leaf litter or silt that might inhibit water flow or put unnecessary weight on the corner joint.
