The reducing wye combines an angled branch connection and a pipe-size transition within a single molded fitting.

The branch enters the main run at an angle, helping guide flow toward the downstream side of the system instead of creating an abrupt perpendicular intersection.

Because the reduction is built directly into the fitting, the assembly can be simpler and more compact than using a standard wye together with a separate reducing fitting.

• NSF/ANSI 14 – Manufactured to applicable requirements for plastic piping system components.
• ASTM D1784 – PVC compound material requirements.
• CSA – Manufactured to applicable Canadian standards as identified by the manufacturer.

Refer to the LESSO technical documentation for the exact standards, certifications, and listings applicable to each size and fitting variation.

Manufactured from durable PVC, this reducing wye is designed for long-term service in underground sewer and drainage environments.

The material provides resistance to corrosion, moisture, soil conditions, and many compatible chemicals while remaining lightweight for easier handling and installation.

Precision-molded hub connections help provide proper fit and alignment with compatible SDR 35 PVC pipe, while the reducing angled branch incorporates the required size transition directly into the fitting body.

Verify all three nominal connection sizes before installation and confirm which opening is the reducing connection.

Confirm compatibility with the SDR 35 PVC pipe sizes used in the main run and branch line.

Determine the intended upstream run, downstream run, branch direction, and size transition before assembling the fitting.

Orient the branch so incoming flow is directed toward the downstream side of the piping system.

Cut all mating pipe ends square and remove burrs, dirt, and debris that could interfere with proper insertion.

Clean and prepare the pipe ends and fitting hubs according to accepted PVC solvent-weld installation procedures.

Dry-fit all three pipe sections before applying primer or solvent cement to confirm size placement, insertion depth, branch orientation, alignment, and drainage slope.

Apply approved PVC primer and solvent cement as required and fully seat each pipe section into its corresponding hub.

Maintain proper fitting orientation and pipe support while the joints set.

Allow completed solvent-weld joints to cure according to the solvent cement manufacturer's recommendations before backfilling or placing the drainage system into service.
