How to Install the Plumb Pak PP20999 Marvel Connector (Step-by-Step)

Installing the PP20999 is straightforward—even for beginners. Follow these steps for a leak-free connection:

1. Cut the Pipe Square: Use a tubing cutter to ensure a clean, perpendicular end. Deburr both inside and outside edges.
2. Check Pipe Insertion Depth: The 1-1/2” tube should insert 1.38 inches (35 mm) into the fitting. Most pipes have depth markings—verify before pushing.
3. Insert Pipe Firmly: Push the pipe straight into the connector until it bottoms out. You should hear or feel a slight click.
4. Test the Connection: Turn on water supply and check for leaks. If installed correctly, it should hold instantly.
5. (Optional) Secure with Clamp: In high-vibration areas (e.g., near pumps), use a support clamp within 2 inches of the fitting.

💡 Pro Tip: Always dry-fit first. Moisture or debris on the pipe can compromise the seal. Wipe with a clean cloth before insertion.

FAQ Section

Q1: Can I use the Plumb Pak PP20999 for underground or outdoor applications?

A: Yes—but only if buried below the frost line and protected from UV exposure. For direct burial, wrap the fitting with waterproof tape or use a protective sleeve. It’s not UV-stable, so prolonged sun exposure can degrade the O-ring.

Q2: Is this fitting suitable for hot water heaters?

A: Absolutely. With a 200°F temperature rating and 200 PSI pressure tolerance, it’s approved for both tank and tankless water heater connections—provided local codes allow push-to-connect fittings in those locations (most do for 1-1/2” lines).

Q3: How do I disconnect the PP20999 if I need to reuse it?

A: Use a Plumb Pak disconnect clip (model DC150). Slide it into the release collar, press evenly around the circumference, and gently pull the pipe out. Never yank—this can damage the grip ring.

Q4: What pipe materials work with this connector?

A: It’s compatible with PEX (A, B, or C), hard-drawn copper (Type K, L, or M), and CPVC—all in 1-1/2” nominal size. Ensure the pipe is clean, round, and within tolerance (±0.005”).

Q5: Does this fitting require a permit or inspection?

A: In most U.S. jurisdictions, push-to-connect fittings like the PP20999 are code-compliant for residential use. However, always check with your local building department—some areas restrict their use in main supply lines.

Q6: Where can I buy the Plumb Pak PP20999?

A: It’s available at major retailers like Home Depot, Lowe’s, and online via Amazon or SupplyHouse.com. Look for the genuine Plumb Pak logo to avoid counterfeits.
