Choose the Perfect Tailpiece for Any Kitchen Sink Install
Installing a new kitchen sink tailpiece is an important part of any sink drain project. Properly sizing and selecting the right tailpiece ensures your new sink will drain quickly and efficiently for years to come.
We'll cover measuring techniques, material options like plastic and chrome, extra considerations like dishwashers, and step-by-step installation instructions.
Why a Tailpiece Matters
A tailpiece is a short length of pipe that connects the sink strainer basket to the curved P-trap below. This simple but vital component creates a tight seal between parts, directing water flow properly and preventing leaks.
Without a tailpiece, it would be extremely difficult to securely join sink drains to the trap. Tailpieces are mandatory in all standard sink drain configurations.
Tailpiece Sizing
Choosing the right diameter tailpiece prevents leaks and mismatches. Start by accurately measuring your sink's drain outlet using calipers or a soft measuring tape.
Common tailpiece sizes include 1 1/4", 1 1/2", and 2" inner diameters to match most household sink drains. It's crucial to match the tailpiece size to your drain outlet diameter.
Plan for Future Changes
When sizing your new tailpiece, also consider possible strainer basket or garbage disposal upgrades down the road. Opting for a slightly larger 2" tailpiece leaves flexibility versus squeezing in an exact 1 1/2" match.
Tailpiece Materials
From plastic to chrome and more, tailpiece materials must withstand constant water contact and potential corrosion over time.
Plastic Tailpieces
Plastic is the most inexpensive option. PVC and ABS plastic tailpieces are easy to adjust by cutting to length. However, plastic can become brittle and crack over years of use.
Chrome-Plated Brass Tailpieces
Chrome-plated brass is durable, resists corrosion, and gives a polished look. Brass tailpieces are sturdier than plastic and available in a wide range of standard drain sizes.
Other Metal Choices
Stainless steel, copper, and other metals also resist corrosion. These tend to be the most expensive but nearly indestructible options.
Additional Tailpiece Considerations
Dishwasher Connections
If you need to attach a dishwasher drain hose, look for tailpieces with an extra inlet port. This allows both sink and dishwasher to connect to the same P-trap.
Tailpiece Length
Measure the distance from your strainer outlet to the top of the P-trap. Buy an extra-long tailpiece and cut with a hacksaw for an exact fit.
Appearance
A chrome finish blends with stainless steel sinks, or coordinate with sink drain finishes. Flexible vs straight tailpieces also affect look.
Step-By-Step Installation Guide
Once you've chosen the perfect tailpiece, installation takes just a few steps:
- Apply thread seal tape to tailpiece threads
- Tighten tailpiece into sink strainer outlet
- Measure and mark for cutting if needed
- Connect tailpiece to P-trap and hand tighten slip nuts
- Confirm no leaks by running water
Always follow manufacturer instructions. Securing the tailpiece properly prevents leaks and provides years of service.
Troubleshooting Tailpiece Problems
If you notice leaks, clogs or poor drainage, the tailpiece may require repair or replacement. Check for cracks or loose slip nuts first before replacing the entire tailpiece.
Adjusting tailpiece length and orientation can also fix some flow problems. But repeated issues usually indicate a full replacement is needed.
