If you’ve ever struggled with a leaky, corroded, or clogged P-trap under your bathroom sink, you know how frustrating—and messy—it can get. Replacing traditional traps often means wrestling with slip nuts, pipe wrenches, and the constant fear of leaks. Enter the Keeney Insta-Plumb Push Fit P Trap 1-1/2”—a modern, tool-free solution that’s trusted by both DIYers and professionals for fast, reliable drain connections. In this guide, we’ll walk you through everything you need to know to install, maintain, and get the most out of this innovative plumbing fixture.
What Is a P-Trap—and Why Does It Matter?
A P-trap is the U-shaped pipe beneath your sink that serves two critical functions:
Prevents sewer gases from backing up into your home.
Catches debris (like hair or small objects) before they clog your main drain line.
According to the International Plumbing Code (IPC), every drain connected to a plumbing fixture must include a trap—making the P-trap non-negotiable for safety and hygiene. Traditional P-traps use threaded slip joints, which can corrode, loosen, or leak over time. That’s where push-fit technology, like the Keeney Insta-Plumb, changes the game.

Step-by-Step Installation Guide (No Experience Needed!)
You don’t need to be a plumber to install the Keeney Insta-Plumb Push Fit P Trap 1-1/2”. Follow these exact steps:
Turn off the water supply and place a bucket under the sink to catch residual water.
Remove the old P-trap by loosening slip nuts (if applicable) or cutting PVC pipes cleanly with a hacksaw.
Measure your tailpiece and drain outlet—ensure both are 1-1/2” in diameter (standard for bathroom sinks).
Dry-fit all components first:
Tailpiece → Vertical inlet of P-trap
Horizontal outlet → Drain stub-out in the wall
Push each pipe firmly into the fitting until you hear a soft click. The stainless steel teeth will grip automatically.
Test for leaks: Run water for 60 seconds at full flow (approx. 2.2 gallons per minute). Check all joints.
Rotate the trap if needed to align with your cabinet layout—no tools required.
🛠️ Pro Tip: If a pipe feels stiff, lightly bevel the end with sandpaper to ensure smooth insertion. Never force it.
Common Problems & How to Fix Them
Even the best systems need occasional attention. Here’s how to troubleshoot:
Leak at the joint? → Pipe may not be fully inserted. Pull it out, check for burrs, and reinsert with firm pressure.
Trap won’t rotate? → Ensure the pipe is fully seated. The O-ring must compress fully before rotation is possible.
Slow drainage? → The P-trap isn’t the issue—check for clogs further down the line. Use a 1/4” drain auger or enzymatic cleaner.
Foul odor from sink? → Evaporation may have emptied the trap. Run water for 10 seconds to refill the U-bend.
Maintenance Tips for Longevity
Monthly: Pour 1 cup of baking soda + 1 cup vinegar down the drain, followed by hot (not boiling) water after 15 minutes.
Every 6 months: Inspect the O-rings for cracks or hardening (rare, but possible in very dry climates).
Never use chemical drain cleaners like Drano—they can degrade rubber seals over time.
With proper care, your Keeney Insta-Plumb Push Fit P Trap can last 10–15 years—matching the lifespan of conventional traps but with far less hassle.
