Clogged sinks, slow drainage, or that dreaded sewer smell creeping up from your kitchen or bathroom? You’re not alone—and the culprit is often a faulty or outdated P-trap. The Keeney Insta Plumb 1-1/2 In. D Plastic P-Trap offers a smart, modern fix: tool-free installation, reliable sealing, and durable construction designed for everyday use. Whether you’re replacing a leaky trap or upgrading during a renovation, this compact yet powerful component can save you time, money, and messy cleanups.
What Is a P-Trap—and Why Does It Matter?
Before diving into the Keeney Insta Plumb model, let’s clarify the basics. A P-trap is the U-shaped pipe under your sink that holds water to block sewer gases from entering your home. Without it, your kitchen or bathroom could be exposed to harmful odors and even dangerous gases like methane and hydrogen sulfide.
According to the International Plumbing Code (IPC), every fixture with a drain must have a trap—making the P-trap not just useful, but legally required in most U.S. jurisdictions. The Keeney Insta Plumb 1-1/2 In. D Plastic P-Trap meets all standard plumbing codes and is certified by IAPMO (International Association of Plumbing and Mechanical Officials), ensuring safety and compliance.

Step-by-Step: How to Install the Keeney Insta Plumb 1-1/2 In. D Plastic P-Trap
Follow these simple steps—no plumbing license required!
- Turn Off Water Supply
Shut off the hot and cold valves under the sink. Open the faucet to drain residual water. - Remove Old P-Trap
Place a bucket underneath. Loosen slip nuts by hand (or with pliers if stuck). Remove and discard the old trap. - Dry Fit the New Assembly
Lay out the Keeney Insta Plumb components: tailpiece, J-bend, and outlet arm. Ensure the outlet aligns with your drainpipe (typically 1-1/2″ diameter). - Connect Tailpiece to Sink Drain
Slide the compression nut and washer onto the tailpiece. Insert into the sink drain and hand-tighten the nut until snug—do not over-tighten. - Attach J-Bend & Outlet Arm
Twist the J-bend into the tailpiece until it clicks. Then connect the outlet arm to your wall drainpipe using the same twist-lock mechanism. - Test for Leaks
Turn water back on. Run 2 liters of water at room temperature (22–28°C) through the sink. Check all joints for drips. If dry—congrats! You’ve just installed a code-compliant, leak-free drain system in under 10 minutes.
💡 Pro Tip: Keep the original packaging—it includes a handy diagram and spare washers for future use.
