Product Information

Full details

The Wavin Osma SquareLine 100mm Gutter System is designed for homeowners and contractors seeking a durable, modern, and efficient rainwater drainage solution for domestic buildings. Its primary benefit lies in the intuitive Flexiclip seal jointing mechanism, which guarantees a watertight connection without requiring complex tools; however, users should note that the system requires specific adaptors if transitioning from the standard square profile to 68mm circular downpipes.

FAQs

Can I use this gutter with circular downpipes?

Yes, but you must use the specific Osma adaptor designed to transition from the 100mm square profile to the 68mm circular pipe.

How much roof area can one downpipe manage?

The system is capable of draining a maximum roof area of 178 square metres when using a single downpipe.

Is any sealant required for the joints?

No, the Flexiclip seal jointing mechanism is designed to be permanently watertight without the need for additional sealants.

What standards does this gutter meet?

The Wavin Osma SquareLine gutter conforms to BS EN 607:2004 standards.

How do I cut the 4m gutter to size?

Use a fine-tooth hacksaw to cut the gutter section. Ensure the cut edge is filed smooth to prevent damage to the joint seals.

Troubleshooting

Joint is not watertight

Check that the Flexiclip is fully engaged and that no debris is trapped within the seal housing.

Gutter sagging

Verify that gutter brackets are correctly spaced and securely fastened to the fascia board.

Water backing up during rain

Clear the gutter channel and downpipe outlet of blockages such as moss or leaves.

Pros and Cons

Pros

Sleek and modern square-profile design
Easy installation thanks to Flexiclip jointing
High capacity drainage for large roof areas
Reliable, long-term watertight seal
Compliance with recognized industry standards

Cons

Requires specific adaptors for circular downpipes
Profile shape may not match traditional round guttering
Installation requires careful alignment for optimal drainage

Setup, Compatibility & Care

For a successful installation, ensure that all mounting brackets are spaced according to manufacturer specifications to support the weight of the gutter when full. The system is designed primarily for 61mm square downpipes; if your property features 68mm circular downpipes, ensure you have the correct `4T874b` compatible adaptors on hand. To maintain the system, perform an annual inspection to clear leaves and debris from the gutter channel and downpipe inlets. Wipe the external surface with a damp cloth and mild soap to maintain the black finish, avoiding abrasive scrubbers that may scratch the protective coating.
