If your plumbing system uses an Arrowhead Brass & Plumbing PK2016 420 Springless Check Valve, you might be facing issues like backflow, low water pressure, or complete valve failure. Replacing it sounds intimidating—but with the right guidance, it’s a manageable DIY task. Many homeowners turn to YouTube for visual help, searching specifically for “Arrowhead Brass & Plumbing PK2016 420Springless Chk Valve Replacement Utube” (note: often misspelled as “Utube” instead of “YouTube”). This guide walks you through everything you need to know—safely, correctly, and efficiently.
What Is the Arrowhead PK2016 420 Springless Check Valve?
Before jumping into replacement, understand what this part does. The Arrowhead PK2016 420 Springless Check Valve is a non-spring, swing-style backflow preventer commonly used in residential and light commercial plumbing. It allows water to flow in one direction only, preventing contamination from reverse flow.
Unlike spring-loaded check valves, this model relies on gravity and flow dynamics, making it quieter and less prone to clogging—ideal for irrigation, well systems, and potable water lines.
According to the Uniform Plumbing Code (UPC), backflow prevention is mandatory in many applications to protect public water supplies. The Arrowhead PK2016 meets ASSE 1013 standards for non-pressure backflow prevention in specific scenarios.
💡 Fun fact: Over 60% of residential backflow incidents involve faulty or missing check valves (EPA WaterSense Report, 2023).
Why Do You Need to Replace It?
Check valves wear out over time. Common signs your Arrowhead PK2016 420 needs replacement include:
- Water hammer or banging pipes
- Reduced water pressure downstream
- Visible leaks around the valve body
- Backflow (water flowing backward into supply lines)
- Corrosion or mineral buildup inside the valve
Ignoring these signs risks system contamination, pipe damage, or even health hazards—especially if connected to irrigation or greywater systems.
How to Find the Right YouTube Tutorial for Replacement
Many users search “Arrowhead Brass & Plumbing PK2016 420Springless Chk Valve Replacement Utube” due to misspellings or voice search errors. To find a reliable video, look for these traits:
✅ Hosted by a licensed plumber or plumbing brand
✅ Shows real installation, not just animation
✅ Includes safety steps (shut-off valves, pressure relief)
✅ Mentions compatible pipe sizes (typically ¾” or 1″)
✅ Has clear, well-lit footage of disassembly steps
🔍 Pro Tip: Add “official” or “licensed plumber” to your YouTube search to filter out low-quality content.
Step-by-Step Replacement Guide (Based on Top YouTube Tutorials)
While videos vary, the best tutorials follow this standardized process. Always turn off main water supply and relieve line pressure before starting.
Tools & Materials Needed:
- Adjustable wrench or pipe wrench
- Teflon tape (plumber’s tape)
- Bucket or towels (for residual water)
- Replacement Arrowhead PK2016 420 valve (confirm size: ¾” or 1″)
- Safety gloves & goggles
Replacement Steps:
- Shut Off Water Supply
Close the main water valve. Open a nearby faucet to drain pressure. - Isolate the Valve Section
If possible, close upstream and downstream shut-off valves. If not, you’ll work on the main line—be prepared for minor water spillage. - Remove Old Valve
Use a wrench to unscrew the valve from both ends. Tip: Support the pipe to avoid twisting fittings loose elsewhere. Expect ½–1 cup of residual water. - Clean Pipe Threads
Wipe threads with a clean rag. Remove old Teflon tape or pipe dope residue. - Install New Valve
Wrap 3–4 clockwise turns of Teflon tape on male threads. Hand-tighten first, then use a wrench for 1.5 additional turns—do not overtighten (brass cracks easily). - Check Orientation
The PK2016 must be installed horizontally, with the flow arrow pointing in the direction of water movement. Installing vertically or backward voids functionality. - Test for Leaks
Slowly turn water back on. Check joints for drips. Run water for 2–3 minutes to flush debris.
⚠️ Never install a springless check valve in vertical upward flow—it won’t seal properly.
Arrowhead PK2016 vs. Other Check Valves: Quick Comparison
| Feature | Arrowhead PK2016 (Springless) | Spring-Loaded Check Valve | Dual-Check Valve |
|---|---|---|---|
| Noise Level | Very quiet | Can chatter or rattle | Moderate |
| Clogging Risk | Low (no spring) | Higher (spring traps debris) | Medium |
| Installation Orientation | Horizontal only | Any orientation | Usually horizontal |
| Backflow Protection Level | Moderate (ASSE 1013) | High (ASSE 1017) | High (ASSE 1013/1017) |
| Best For | Irrigation, well pumps, low-pressure lines | High-pressure systems, municipal lines | Potable water with backflow risk |

Common Mistakes to Avoid
Even experienced DIYers make these errors:
- Installing upside down or backward → Causes immediate backflow
- Overtightening brass fittings → Cracks valve body (brass is softer than steel)
- Skipping Teflon tape → Leads to slow leaks
- Using in vertical lines → Gravity won’t close the disc properly
- Ignoring flow direction → Arrow must match water path
One YouTube commenter shared: “I installed mine backward—two days later, my well pump burned out from cycling. Cost me $800.” Don’t be that person.
FAQ Section
Q1: Can I replace the Arrowhead PK2016 myself?
A: Yes—if you’re comfortable shutting off water and using basic tools. If your system lacks isolation valves, consider hiring a plumber to avoid flooding.
Q2: Is “Utube” the same as YouTube?
A: No—“Utube” is a common misspelling. Always search on YouTube.com for verified plumbing tutorials. Typing “Utube” may lead to unreliable or scam sites.
Q3: What pipe size does the PK2016 fit?
A: The PK2016 420 is designed for ¾-inch NPT (National Pipe Thread) connections. Verify your pipe size before purchasing.
Q4: Why is it called “springless”?
A: It uses a hinged disc that swings open with flow and closes via gravity—no internal spring. This reduces maintenance and noise.
Q5: How long does this valve last?
A: With clean water and proper installation, 5–10 years. Hard water or sand can reduce lifespan to 2–3 years.
Q6: Where can I buy a genuine Arrowhead PK2016?
A: Reputable sources include Ferguson, SupplyHouse.com, or Amazon (sold by Arrowhead or authorized dealers). Avoid ultra-cheap knockoffs—they often fail within months.
