Setup and Installation
This tailpiece is designed for connection to a sink drain and a P-trap assembly. Follow these general steps for installation:
- Prepare the Drain: Ensure the sink drain opening is clean and free of debris.
- Apply Plumber's Putty (if applicable): If your drain assembly requires it, apply a bead of plumber's putty around the underside of the drain flange that sits in the sink.
- Install Drain Assembly: Insert the drain assembly into the sink opening. From underneath the sink, attach any necessary washers and nuts to secure the drain assembly.
- Connect Tailpiece: Slide the large nut and washer (typically provided with the drain assembly or P-trap) onto the tailpiece. Insert the flared end of the tailpiece into the bottom of the drain assembly.
- Secure Connection: Hand-tighten the nut onto the drain assembly. Use a wrench to tighten an additional quarter to half turn, being careful not to overtighten.
- Connect to P-Trap: Connect the lower end of the tailpiece to your P-trap assembly using the appropriate slip nuts and washers. Ensure a tight, leak-free seal.
- Test for Leaks: Turn on the water supply and run water through the sink drain, checking carefully for any leaks at all connections. Tighten connections slightly if leaks are observed.

Operating (Function)
The PROFLO PFTPB100 tailpiece serves as a critical connection between the sink drain assembly and the P-trap. Its function is passive, providing a sealed conduit for wastewater to flow from the sink into the drainage system, preventing leaks and ensuring proper plumbing function.
Maintenance
Regular maintenance helps ensure the longevity and proper function of your brass tailpiece:
- Periodic Inspection: Periodically inspect the tailpiece and its connections for any signs of leaks, corrosion, or damage.
- Cleaning: Clean the exterior of the tailpiece with a soft cloth and mild soap and water if necessary. Avoid abrasive cleaners or harsh chemicals, as these can damage the brass finish.
- Check Connections: If any minor drips are observed, gently tighten the slip nuts. Do not overtighten.
Troubleshooting
Most issues related to a tailpiece involve leaks. Here are common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaking from connections | Loose nuts or worn washers | Gently tighten slip nuts. If leaks persist, disassemble, inspect washers for damage, and replace if necessary. Ensure washers are correctly seated. |
| Persistent drip after tightening | Cracked tailpiece or damaged threads | Inspect the tailpiece for visible cracks or damage. If damaged, the tailpiece will need to be replaced. |
| Slow drainage | Blockage in drain or P-trap | The tailpiece itself is unlikely to cause a blockage unless severely corroded internally. Check the sink stopper, drain assembly, and P-trap for clogs. |
