SWR Door Bend Vent – 4″(110mm)

Description

The SWR Door Bend Vent, a 4″ (110mm) fitting, is a highly functional and robust component for any SWR (Soil, Waste, and Rainwater) drainage system. It’s a specialized bend that not only changes the direction of a pipe by 90 degrees but also incorporates two critical features: a door for maintenance and a vent. Made from durable uPVC, this fitting is engineered for optimal performance and long-term reliability.

Uses:

• Creating a 90-Degree Turn: This fitting is used to change the direction of a pipe by a right angle, typically at the base of a vertical stack or to navigate a corner.

• Providing a Maintenance Point: The “door” feature—a removable, threaded cap—allows for easy inspection and clearing of blockages. This is especially useful at a 90-degree turn, where clogs are more likely to occur.

• Venting the System: The vent, or “vent cowl,” allows for the passage of air into and out of the drainage system. This is crucial for maintaining proper pressure within the pipes, which prevents the “siphoning” of water from P-traps, a common cause of foul odors.

Advantages:

• Triple-Functionality: This all-in-one fitting serves three vital functions: it changes the direction of the pipe, provides a convenient access point for cleaning, and vents the system to prevent a vacuum from forming. This combination saves on the cost and complexity of installing separate fittings.

• Clog Prevention and Removal: While 90-degree bends can be prone to clogs, the access door makes it simple to clear any blockages that do occur.

• Odor Control: The vent is a critical component for ensuring a hygienic environment. By preventing a vacuum, it stops water from being sucked out of the P-traps, which are designed to block sewer gases from entering your home or building.

• High Durability: Constructed from high-quality uPVC, this fitting is resistant to rust, corrosion, and a wide range of chemicals commonly found in wastewater.

• Easy Installation: Despite its advanced features, it maintains the lightweight and easy-to-install properties of standard SWR fittings. It can be installed quickly using a push-fit or solvent cement joint, reducing labor time and costs.
