SWR Bell Mouth Trap – 4″ x 2-1/2″ (110mm x 75mm) – Pasted

Description

The SWR Bell Mouth Trap, sized 4″ x 2-1/2″ (110mm x 75mm) with a “pasted” joint, is a highly specialized and robust solution for external drainage systems. This fitting is expertly engineered to handle large volumes of rainwater while creating a permanent, leak-proof barrier against foul sewer gases. The specified dimensions ensure a perfect fit for a 4-inch (110mm) main pipe and a 2.5-inch (75mm) branch line, which are common sizes for residential and commercial applications.

Uses:

• Permanent External Drainage: This trap is used to permanently collect surface water from a variety of external areas, such as roofs via downpipes, paved yards, or balconies. Its wide, bell-shaped opening efficiently captures large volumes of water, preventing pooling and potential damage.

• Creating a Reliable Water Seal: The “pasted” joint ensures that the trap’s internal water seal remains reliable and does not get compromised by a loose connection. This seal is crucial for preventing unpleasant sewer gases from escaping into the environment, ensuring a safe and hygienic outdoor space.

• Connecting Different Pipe Sizes: This fitting is specifically designed to connect a smaller 2.5-inch (75mm) branch line to a larger, more efficient 4-inch (110mm) main drainage pipe, optimizing the flow and preventing common bottlenecks.

Advantages:

• Ultimate Leak-Proof Protection: Unlike push-fit or rubber ring fittings, the “pasted” joint is created by a chemical solvent cement that fuses the pipe and fitting together. This process, known as solvent welding, creates a single, monolithic, and permanent bond that is entirely leak-proof and can withstand high pressure and external forces.

• Superior Water Intake: The “bell mouth” design is highly efficient at collecting water, especially in heavy rainfall. This feature helps prevent flooding and ensures rapid drainage, which is essential for protecting a property’s foundation and landscaping.

• High Durability and Longevity: As a uPVC fitting, it is completely resistant to rust, corrosion, and the chemicals found in typical drainage. It is built to withstand exposure to the elements and the rigors of external use, guaranteeing a long service life of 50 years or more.

• Cost-Effective: By providing a long-lasting, low-maintenance solution that helps prevent costly sewer-line blockages and ensures a permanent connection, this trap is an excellent long-term investment for the health and hygiene of your property.
