Wavin OsmaSoil 110mm Ringseal Single Socket Single Branch 87.5 Degree 4S190 Grey

The 87.5-degree angle is specifically chosen to provide an optimal downward slope (fall) for sanitary waste, helping to ensure efficient flow and prevent blockages in drainage systems.

No, this fitting features a push-fit ring seal system and is not designed for solvent weld application. Use only compatible push-fit pipes and adaptors.

The keyway ensures that when a boss socket adaptor is installed, it is positioned correctly to maintain the designed fall of the main pipe, preventing flow issues.

While made of durable PVC-U, this fitting is specifically designed for above-ground sanitary waste removal. For underground applications, consult relevant drainage standards and products.

The Wavin OsmaSoil 110mm fitting is Kitemarked to BS EN 1329-1:2000, which relates to pipes and fittings made of rigid PVC-U for soil, waste, and drain systems.

A watertight seal is achieved by properly lubricating the pipe end and socket, then fully inserting the pipe into the socket until it reaches the internal stop. Ensure the ring seal remains correctly seated during insertion.

Ensure the pipe was fully inserted into the socket and the ring seal is correctly seated. Check for damage to the seal or pipe end. Re-lubricate and re-insert.

Ensure the pipe end and socket are clean and free of obstructions. Apply more appropriate silicone lubricant. Do not force the joint; check for misalignments.

Verify that all fittings used in the run have the correct angle and that the overall system gradient is sufficient. Ensure the boss socket adaptor (if used) is correctly positioned to maintain the primary fall.
