3. Setup and Installation
The Lesso America 402 Series PVC Reducing Tee is designed for easy solvent cementing. Proper preparation and application are crucial for a secure, leak-free connection. Always consult local plumbing codes and the solvent cement manufacturer's instructions for specific requirements and curing times.
Installation Steps:
- Preparation: Ensure pipe ends are cut square, deburred, and chamfered. Clean pipe ends and the inside of the fitting sockets thoroughly to remove dirt, grease, and moisture.
- Dry Fit: Test fit the pipe into the fitting socket. The pipe should enter the socket easily for about one-third to two-thirds of the socket depth.
- Primer Application: If required by local codes or the solvent cement manufacturer, apply a generous coat of PVC primer to both the pipe end and the inside of the fitting socket. Allow the primer to soften the surfaces for the recommended time.
- Cement Application: Apply a uniform, heavy coat of PVC solvent cement to the outside of the pipe end and a medium coat to the inside of the fitting socket. Work quickly, as solvent cement dries rapidly.
- Joining: Immediately insert the pipe into the fitting socket with a quarter turn until it bottoms out. Hold the joint firmly for at least 30 seconds to prevent the pipe from pushing out.
- Curing: Wipe off any excess cement. Allow the joint to cure for the recommended time before handling or pressurizing the system. Curing times vary based on pipe size, temperature, and humidity.

4. Operating Principles
Once properly installed and cured, the Lesso America 402 Series PVC Reducing Tee functions as a permanent connection point within a fluid transfer system. It allows for the reduction of flow from a main line to a branch line, or the connection of different pipe sizes, while maintaining system integrity and high-flow capacity. The fitting is designed to withstand the pressures and temperatures typical for Schedule 40 PVC applications.
5. Maintenance
Lesso America 402 Series PVC fittings are designed for long-term, maintenance-free operation under normal conditions. Their inherent corrosion and UV resistance contribute to their durability.
- Visual Inspection: Periodically inspect the plumbing system for any signs of external damage, leaks, or stress on the fittings.
- Chemical Exposure: Avoid exposing fittings to chemicals known to be incompatible with PVC, as this can compromise the material's integrity.
- Temperature Extremes: While UV resistant, prolonged exposure to extreme temperatures outside the recommended operating range for Schedule 40 PVC can affect performance.
6. Troubleshooting
Most issues related to PVC fittings arise during or shortly after installation.
- Leakage at Joints: This is the most common issue and is typically caused by improper solvent cementing, insufficient curing time, or damage to the pipe or fitting during installation. If a leak occurs, the affected joint must be cut out and re-installed following proper procedures.
- Cracking or Breakage: Can result from excessive external stress, impact, or exposure to temperatures outside the PVC's operating range. Ensure proper support for piping and protect installations from physical damage.
