If you own aKeurig B150 or K150, you know how convenient it is to brew coffee with the push of a button. But constantly refilling the water reservoir can be tedious—especially in high-traffic offices or busy households. That’s where a direct water line plumb kit comes in. In this guide, we’ll walk you through clear, reliable Keurig B150 or K150 Direct Water Line Plumb Kit Instructions so you can enjoy uninterrupted brewing without manual refills.
Whether you’re a facility manager, small business owner, or coffee enthusiast, this tutorial is designed for beginners and pros alike—no plumbing degree required!
What Is a Keurig B150/K150 Plumb Kit?
A plumb kit (or direct water line conversion kit) allows your Keurig B150 or K150 to connect directly to your building’s cold water supply, eliminating the need to refill the internal reservoir. This is especially useful in commercial settings like offices, hotels, or cafés where multiple cups are brewed daily.
💡 Did You Know? According to Keurig’s commercial division, businesses using plumbed-in brewers report up to 30% faster service times during peak hours compared to reservoir-only models.
The official kit (often labeled as the Keurig Direct Plumb Kit – Model K-DCPLB) includes:
Solenoid valve
Filter housing & inline filter
Mounting bracket
Tubing (typically 25 ft)
Fittings and connectors
Note: The B150 and K150 are nearly identical machines—the K150 is simply the newer branding. The same plumb kit works for both.
Do I Need Professional Help to Install It?
While the installation is DIY-friendly, it does require basic plumbing knowledge. If you’re comfortable turning off your water supply, using a drill, and connecting tubing, you can likely handle it yourself.
However, if your local building codes require licensed plumbing work (common in commercial spaces), consult a professional. Incorrect installation could lead to leaks, water damage, or voided warranties.
🛠️ Expert Tip: Always check your local regulations before starting. The International Plumbing Code (IPC) governs many U.S. jurisdictions and may affect your setup.
Step-by-Step Installation Guide
Follow these precise steps to install your Keurig B150 or K150 Direct Water Line Plumb Kit safely and correctly.
⚙️ Tools & Materials Needed:
Adjustable wrench
Drill & ¼” drill bit
Teflon tape
Bucket or towel (for drips)
Screwdriver
Access to cold water line (½” supply recommended)
Step 1: Turn Off Power & Water Supply
Unplug your Keurig.
Shut off the nearest cold water valve.
Open a nearby faucet to relieve pressure.
Step 2: Remove the Water Reservoir
Lift out the removable reservoir from the back of the machine.
Set it aside—you won’t need it once plumbed.
Step 3: Mount the Solenoid Valve Bracket
Locate the rear panel of your Keurig.
Use the included bracket to mount the solenoid valve inside the unit (usually on the left side).
Secure with screws (included).
Step 4: Connect the Water Line
Drill a ¼” hole in your countertop or cabinet (if routing from below).
Feed the ¼” polyethylene tubing from your cold water supply up to the Keurig.
Attach the tubing to a ¼” compression fitting on your cold water line (use Teflon tape on threads).
Connect the other end to the inlet of the solenoid valve.
✅ Pro Tip: Leave 6–8 inches of slack in the tubing behind the brewer for easy movement during maintenance.
Step 5: Install the Inline Filter
Attach the filter housing between the solenoid valve and the Keurig’s internal water inlet.
Insert the carbon filter (included) to prevent sediment and chlorine from affecting taste or damaging internal components.
Step 6: Reconnect Internal Tubing
Route the output tube from the solenoid to the Keurig’s original reservoir inlet port (inside the unit).
Ensure all connections are snug but not over-tightened.
Step 7: Power On & Prime the System
Turn the water supply back on.
Plug in the Keurig.
Run 3–4 rinse cycles (without a K-Cup) to flush air from the lines.
Discard the first 2 liters of water to ensure clean flow.
🌡️ Ideal Water Temp: Your cold water line should be between 22–28°C (72–82°F) for optimal brewing performance.

❌ May require professional help in commercial settings
Common Mistakes to Avoid
Skipping the inline filter → Leads to scale buildup and poor coffee taste.
Using hot water lines → Can damage internal components; only cold water is safe.
Over-tightening fittings → Causes cracks or leaks in plastic tubing.
Ignoring local codes → Could result in failed inspections or insurance issues.
Maintenance Tips After Installation
Replace the inline filter every 6 months (or per manufacturer guidelines).
Inspect tubing annually for kinks, cracks, or mineral deposits.
Run a descaling cycle every 3–6 months using Keurig-approved solution.
Keep the area around the solenoid valve dry and dust-free.
FAQ Section
Q1: Does the plumb kit void my Keurig warranty?
A: No—if installed correctly using Keurig’s official kit, your warranty remains intact. However, damage caused by improper installation (e.g., water leaks) may not be covered.
Q2: Can I switch back to the reservoir after plumbing?
A: Yes! Simply disconnect the tubing, remove the solenoid and filter, and reinsert the original water tank. Keep all parts in case you need to revert.
Q3: Where can I buy the official Keurig plumb kit?
A: The genuine Keurig Direct Plumb Kit (Model K-DCPLB) is available on Keurig.com, Amazon, and authorized commercial suppliers like WebstaurantStore or Espresso Outlet.
Q4: Why is my plumbed Keurig leaking?
A: Most leaks occur at connection points. Check that all fittings are hand-tight plus a quarter-turn with a wrench. Also inspect tubing for cuts or improper insertion into quick-connect fittings.
Q5: Can I use this kit with other Keurig models?
A: The K-DCPLB kit is specifically designed for B150/K150. It will not fit K-Café, K-Elite, or home-use models. Commercial models like the K3000 or K4000 require different kits.
Q6: How much water pressure is required?
A: Keurig recommends 20–80 PSI. If your building’s pressure exceeds 80 PSI, install a pressure-reducing valve to avoid damaging the solenoid.
