NIBCO Fig No 917-B 2-inch Copper Test Cap Instruction Manual

Introduction

This manual provides essential instructions for the proper installation and use of the NIBCO Fig No 917-B 2-inch Copper Test Cap. This product is designed for use in residential and commercial drain, waste, and vent (DWV) systems for repair and testing purposes. Please read these instructions carefully before proceeding with installation to ensure safe and effective use.

Product Overview

The NIBCO Fig No 917-B is a wrot copper DWV test cap. It is specifically designed to seal the end of a 2-inch copper pipe in drain, waste, and vent systems. Its primary function is to facilitate pressure testing of plumbing systems or to temporarily cap off a line during repairs or construction, providing a reliable and dezincification-resistant seal.

Installation Instructions

The NIBCO Fig No 917-B Copper Test Cap is designed for solder connection. Proper soldering techniques are crucial for a leak-free seal. Always ensure the work area is well-ventilated and follow all safety precautions.

Required Tools and Materials:

• Propane or MAPP gas torch
• Lead-free solder
• Soldering flux
• Wire brush or abrasive cloth (for cleaning pipe)
• Safety glasses and heat-resistant gloves
• Fire extinguisher (for safety)

Step-by-Step Installation:

1. Prepare the Pipe: Ensure the end of the copper pipe where the cap will be installed is clean, dry, and free of burrs. Use a wire brush or abrasive cloth to thoroughly clean the outside surface of the pipe end and the inside surface of the test cap. This creates a clean, receptive surface for the solder to adhere to.
2. Apply Flux: Apply a thin, even coat of soldering flux to both the cleaned pipe end and the inside surface of the test cap. Flux helps prevent oxidation during heating and allows the solder to flow properly into the joint.
3. Position the Cap: Place the NIBCO copper test cap firmly onto the end of the prepared copper pipe. Ensure it is seated completely and evenly, creating a snug fit.
4. Heat the Joint: Using a torch, apply heat evenly around the circumference of the joint where the cap meets the pipe. Keep the flame moving to avoid overheating one spot. The goal is to heat the copper pipe and cap to the correct soldering temperature, indicated by the flux bubbling and turning clear.
5. Apply Solder: Once the joint is hot enough, touch the lead-free solder to the joint, opposite the flame. The heat from the pipe and cap should melt the solder, drawing it into the joint by capillary action. Apply enough solder to create a complete, continuous seal around the entire circumference of the joint.
6. Cool and Clean: Remove the flame and allow the joint to cool naturally without disturbance. Do not attempt to cool the joint rapidly with water. Once cool, wipe away any excess flux residue with a damp cloth to prevent corrosion.
7. Test for Leaks: After installation, perform a pressure test on the DWV system according to local plumbing codes to ensure there are no leaks at the cap connection.

Operation

Once properly installed, the NIBCO Fig No 917-B Copper Test Cap functions as a permanent or temporary seal for the end of a 2-inch copper DWV pipe. Its operation is passive, providing a watertight and airtight closure essential for system testing, isolation, or capping off unused lines.

Maintenance

The NIBCO Fig No 917-B Copper Test Cap requires minimal maintenance once installed correctly. Periodically inspect the soldered joint for any signs of corrosion, physical damage, or leakage, especially if the cap is exposed to harsh environments or frequent temperature changes. Due to its dezincification-resistant properties, the cap is designed for long-term durability and performance.

Troubleshooting

Issue: Leakage at the Cap Connection

• Possible Cause 1: Insufficient solder or improper solder flow during installation.
• Solution 1: Drain the system, clean the joint area thoroughly, reapply flux, and re-solder the connection, ensuring adequate heat and solder penetration around the entire joint.
• Possible Cause 2: Improper cleaning of pipe and cap surfaces before soldering.
• Solution 2: If possible without damaging the pipe, carefully remove the cap, thoroughly clean and re-prepare both the pipe and cap surfaces, then re-solder following all installation steps.
• Possible Cause 3: Physical damage to the cap or pipe.
• Solution 3: Inspect for any visible cracks, dents, or other damage. If damaged, replace the cap or the affected pipe section and re-install according to instructions.

Safety Information

• Always wear appropriate personal protective equipment (PPE), including safety glasses and heat-resistant gloves, when handling tools and materials for soldering.
• Ensure adequate ventilation in the work area when soldering to avoid inhaling fumes from flux and solder.
• Keep a fire extinguisher readily available when working with open flames.
• Allow soldered joints to cool completely before touching or applying pressure to prevent injury and ensure joint integrity.
• Follow all local plumbing codes and regulations for installation and testing of DWV systems.
