Say Goodbye to Leaky Drains—Meet Your New Go-To Fix
If you’ve ever spent a frustrating Saturday trying to stop a dripping bathroom sink or wrestling with PVC glue under a cramped vanity, you’re not alone. Most homeowners dread plumbing repairs—but what if you could fix a 1-1/2 inch drain connection in under 5 minutes, without glue, tools, or professional help? Enter the Keeney Insta Plumb 1-1/2 In. D Plastic Marvel Connector—a clever, code-compliant solution trusted by DIYers and pros alike for fast, reliable drain connections.
What Is the Keeney Insta Plumb 1-1/2 In. D Plastic Marvel Connector?
The Keeney Insta Plumb 1-1/2 In. D Plastic Marvel Connector is a push-fit, solvent-free drain fitting designed specifically for 1-1/2 inch diameter pipes commonly found in bathroom sinks, tubs, and lavatories. Made from durable, corrosion-resistant ABS plastic, it creates a watertight seal by compressing an internal O-ring when the pipe is inserted—no glue, clamps, or threading required.
Unlike traditional slip-joint or glued PVC connections, this connector installs in seconds and can be reused if you ever need to disassemble your drain. It’s approved for use in residential plumbing systems across the U.S. and meets ASTM D2661 (Standard Specification for ABS Plastic Pipe) and IAPMO certification standards.
💡 Pro Tip: According to the Plumbing-Heating-Cooling Contractors Association (PHCC), push-fit connectors like the Insta Plumb can reduce minor drain repair time by up to 70% compared to conventional methods.
Why Choose the Keeney Insta Plumb Over Traditional Methods?
Let’s be honest—traditional drain connections are messy and error-prone. Glue can dry too fast, slip joints leak if overtightened, and disassembly often means cutting pipes. Here’s how the Keeney Insta Plumb stacks up:
| Installation Time | 15–30 mins (plus cure time) | 10–15 mins | Under 5 mins |
| Tools Required | Pipe cutter, primer, glue | Wrench, pliers | None |
| Reusable? | No | Yes (but parts wear) | Yes—fully reusable |
| Leak Risk | High if not prepped properly | Moderate (seal degrades) | Very low (tested to 4.3 PSI) |
| Code Compliant? | Yes | Yes | Yes (IAPMO, UPC listed) |
The connector’s secret lies in its dual-seal design: an inner O-ring creates a pressure-tight barrier, while the outer compression ring grips the pipe securely—even if it’s slightly out of round.
How to Install the Keeney Insta Plumb 1-1/2 In. D Connector (Step-by-Step)
Don’t worry—you don’t need plumbing experience. Follow these 5 simple steps for a leak-free install:
- Turn off water supply and clear the area under the sink or tub. Place a towel to catch minor drips.
- Cut the existing pipe cleanly using a hacksaw or PVC cutter. Ensure the end is smooth and square—no burrs or rough edges. Ideal pipe insertion depth: 1-1/4 inches.
- Dry-fit the connector: Push the pipe into the Keeney Insta Plumb 1-1/2 In. D Plastic Marvel Connector until it bottoms out. You should feel slight resistance—this means the O-ring is engaging.
- Check alignment: Make sure the connected pipes are straight and not under tension. Misalignment can cause premature seal failure.
- Test immediately: Run water for 2–3 minutes. Check for drips at the joint. If dry, you’re done! No waiting for glue to cure.
🛠️ Real-World Test: In a 2023 DIY Network field test, 48 homeowners installed the Insta Plumb connector with a 96% first-time success rate—even those with zero plumbing experience.

This little connector shines in high-moisture, low-pressure applications:

FAQ: Your Top Questions Answered
Q: Can I use the Keeney Insta Plumb on metal pipes?
A: No. It’s designed specifically for plastic pipes (ABS or PVC) with a 1-1/2 inch outer diameter. Metal pipes won’t compress the O-ring properly and may scratch the seal.
Q: Is this connector up to plumbing code?
A: Yes! It’s IAPMO-listed and complies with the Uniform Plumbing Code (UPC) for non-pressurized drainage systems in residential settings.
Q: What if my pipe is slightly smaller or larger than 1-1/2 inches?
A: Measure carefully. The connector fits pipes with an outer diameter of 1.610 inches (standard for 1-1/2” nominal drain pipe). Even a 1/16” variance can cause leaks. Use calipers if unsure.
Q: Can I disconnect and reuse it later?
A: Absolutely. Simply pull the pipe out (may require gentle twisting), inspect the O-ring for damage, and reinstall. Keeney says the connector lasts 5+ reuse cycles if handled properly.
Q: Does it work horizontally or only vertically?
A: It works in any orientation—vertical, horizontal, or angled—as long as the pipe is fully inserted and not under stress.
Q: What’s the maximum water temperature it can handle?
A: 140°F (60°C). Avoid connecting it directly to dishwasher discharge lines or hot water heater drains.
