1. Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of your BLANCO Siphon 137 262 kitchen sink drain trap. Please read this manual thoroughly before beginning installation to ensure proper function and longevity of the product.

This image displays the BLANCO Siphon 137 262, a white plastic drain trap designed for kitchen sinks. It features a standard P-trap section connected to a flexible, corrugated hose, allowing for adjustable positioning to connect to the waste pipe. An additional inlet is visible on the upper part of the P-trap, likely for connecting an overflow or dishwasher drain.

4. Setup and Installation

Follow these steps for proper installation:

1. Preparation: Ensure the water supply to the sink is turned off. Clear the area under the sink and have a bucket ready to catch any residual water.
2. Remove Old Siphon (if applicable): Loosen the nuts connecting the old siphon to the sink drain and the wall waste pipe. Carefully remove it, draining any water into the bucket.
3. Connect to Sink Drain: Attach the upper part of the BLANCO Siphon 137 262 (P-trap section) to the sink drain outlet. Use the provided washer/seal and hand-tighten the connection nut (Input Connection Type: Push-fit, Input Connection Size: 1.5 Inches). Ensure a snug fit without overtightening.
4. Connect Flexible Hose: Attach the flexible corrugated hose to the P-trap outlet. Secure it with the provided nut and seal.
5. Connect to Waste Pipe: Extend and position the flexible hose to align with the wall waste pipe. Connect the end of the flexible hose to the waste pipe using the appropriate compression fitting (Output Connection Type: Compression, Output Socket Size: 1.5 Inches). Trim the flexible hose if necessary to achieve a proper fit, ensuring a slight downward slope for drainage.
6. Connect Additional Inlets (Optional): If connecting an overflow or dishwasher drain, attach it to the designated inlet on the P-trap using the appropriate fittings and seals. The siphon has 2 ports.
7. Test for Leaks: Once all connections are made, turn on the water supply to the sink. Fill the sink with water and then drain it, carefully checking all connections for any signs of leakage. Tighten connections slightly if leaks are detected, but avoid excessive force.

5. Operation

The BLANCO Siphon 137 262 operates by maintaining a small amount of water in its P-trap bend. This water creates a barrier, preventing sewer gases and odors from rising through the drain into your kitchen. When water drains from the sink, it flows through the siphon, replenishing the water seal and carrying away waste.

6. Maintenance

Regular maintenance ensures optimal performance and prevents issues:

• Regular Cleaning: Periodically clean the siphon to prevent buildup of grease, food particles, and other debris that can cause blockages. You can usually unscrew the bottom cap of the P-trap (if present) or disassemble the siphon for thorough cleaning.
• Check for Leaks: Regularly inspect all connections for any signs of drips or moisture. Address any leaks promptly by tightening connections or replacing worn seals.
• Avoid Harsh Chemicals: Do not use harsh chemical drain cleaners, as these can damage the plastic components and seals of the siphon. Use natural alternatives or mechanical methods for clearing clogs.

7. Troubleshooting

• Leaking Siphon:
  • Check all connection nuts. Hand-tighten them carefully.
  • Inspect seals and washers for proper placement and damage. Replace if necessary.
• Slow Drainage or Blockage:
  • Turn off water supply. Place a bucket under the siphon.
  • Carefully disassemble the siphon (P-trap and flexible hose sections).
  • Remove any accumulated debris or clogs. Clean all parts thoroughly.
  • Reassemble, ensuring all seals are correctly seated and connections are secure.
• Unpleasant Odors:
  • Ensure the siphon always contains water to maintain the water seal. Run water for a few seconds if the sink has been unused for a long time.
  • Clean the siphon as described above to remove any odor-causing buildup.
  • Check for proper ventilation in your plumbing system.
