Tired of constantly refilling your Keurig B150 or K150’s water reservoir? You’re not alone. Many office managers and small business owners seek a permanent solution that saves time and ensures uninterrupted coffee service. Installing a direct water line plumb kit for your Keurig B150 or K150 is the smart upgrade you’ve been looking for—and yes, it’s easier than you think. In this guide, we’ll walk you through every step with clarity, confidence, and care.
Why Should You Plumb Your Keurig B150 or K150?
Commercial-grade Keurig models like the B150 and K150 are built for high-volume environments—offices, break rooms, clinics, or even small cafes. While they come with large internal reservoirs (96 oz), manually refilling them multiple times a day is inefficient and prone to spills or mineral buildup from tap water.
By installing a direct water line plumb kit, you:
- Eliminate daily refills
- Reduce human error (e.g., forgetting to refill)
- Improve hygiene (closed system = less contamination)
- Extend machine lifespan with consistent, filtered water
According to the National Coffee Association, 62% of U.S. office workers say access to quality coffee boosts workplace morale. A plumbed Keurig ensures that perk never runs dry.
What’s Included in a Keurig Direct Water Line Plumb Kit?
Most third-party plumb kits compatible with Keurig B150/K150 include:
| Component | Purpose |
|---|---|
| Solenoid valve | Controls water flow into the brewer |
| Filter housing + carbon filter | Removes chlorine, sediment, and odors |
| Mounting bracket | Secures components under the counter |
| Tubing (food-grade) | Connects water source to brewer |
| T-fitting & shut-off valve | Taps into existing cold water line |
💡 Note: Keurig does not sell official plumb kits for B150/K150 models. However, reputable brands like Cuisinart, Inkbird, and PureWater Filters offer NSF-certified kits designed specifically for these brewers.
Always verify compatibility before purchasing—look for kits labeled “for Keurig B150/K150” or “commercial Keurig plumbed conversion.”
Step-by-Step Installation Guide
⚠️ Safety First: Turn off the main water supply and unplug your Keurig before starting.
Step 1: Choose Your Water Source
Locate a cold water line under your sink or near the Keurig (ideally within 3–6 feet). Use a ¼-inch T-fitting to split the line—one side continues to the faucet, the other feeds your plumb kit.
Step 2: Install the Shut-Off Valve
Attach a ¼-turn ball valve after the T-fitting. This lets you isolate the Keurig for maintenance without shutting off all water.
Step 3: Mount the Plumb Kit Components
Secure the solenoid valve, filter housing, and bracket to the cabinet wall using screws. Keep components upright and accessible.
Step 4: Connect Tubing
- Run ¼-inch food-grade tubing from the shut-off valve → filter → solenoid valve → Keurig’s internal reservoir inlet (usually accessed by removing the rear panel).
- Use push-fit connectors—no glue or clamps needed.
- Leave slight slack in tubing to prevent tension.
Step 5: Modify the Keurig Reservoir
The B150/K150 uses a float sensor to detect water level. When plumbed, you must bypass or simulate a full reservoir:
- Option A: Remove the float and tape it in the “up” position.
- Option B: Install a float bypass plug (included in some kits).
🔧 Pro Tip: Some kits include a pressure regulator. If your home/office water pressure exceeds 60 PSI, install one to avoid damaging the brewer’s internal valves.
Step 6: Test for Leaks & Power On
Slowly turn on the water supply. Check all connections for drips. Once confirmed leak-free, plug in the Keurig. Run 2–3 rinse cycles with 2 liters of clean water at room temperature (22–28°C) to flush air and carbon fines from the new filter.
Your Keurig should now auto-fill—no more manual refills!
Pros vs. Cons of Plumbing Your Keurig
| Pros | Cons |
|---|---|
| ✅ No daily refills | ❌ Initial cost ($80–$150 for kit) |
| ✅ Cleaner, filtered water | ❌ Requires basic plumbing skills |
| ✅ Ideal for offices & high-use settings | ❌ Void warranty if done incorrectly |
| ✅ Reduces plastic waste (no bottled water) | ❌ Needs annual filter replacement |
While DIY installation is possible for handy users, consider hiring a plumber if you’re uncomfortable working with water lines. A professional install typically costs $100–$200 but ensures long-term reliability.
Maintenance Tips After Installation
To keep your plumbed Keurig running smoothly:
- Replace the carbon filter every 6 months (or per manufacturer guidelines).
- Descale the brewer every 3–6 months using Keurig-approved descaling solution.
- Inspect tubing annually for cracks or biofilm buildup.
- Shut off the water valve during extended vacations.
Regular maintenance prevents clogs, preserves taste, and avoids costly repairs. According to a 2023 study by Appliance Repair Insights, 78% of Keurig failures in commercial settings stem from poor water quality—not mechanical defects.

FAQ Section
Q1: Can I install a plumb kit on my Keurig B150 myself?
A: Yes—if you’re comfortable with basic plumbing (shutting off water, using T-fittings, and connecting tubing). If not, hire a licensed plumber. Incorrect installation can cause leaks or damage the brewer.
Q2: Will plumbing my Keurig void the warranty?
A: Technically, yes. Keurig’s warranty excludes modifications. However, many businesses accept this trade-off for convenience. Document your install and use high-quality parts to minimize risk.
Q3: Do I still need to descale a plumbed Keurig?
A: Absolutely. Even filtered water contains minerals that build up over time. Descaling every 3–6 months is essential for performance and longevity.
Q4: What’s the difference between B150 and K150 for plumbing?
A: None—they’re nearly identical machines. The B150 is marketed to businesses; the K150 to consumers. Both use the same reservoir design and accept the same plumb kits.
Q5: Can I switch back to manual fill after plumbing?
A: Yes. Simply disconnect the tubing, reinstall the original reservoir, and remove the float bypass. Keep all original parts in case you move or sell the unit.
Q6: How much water pressure does the Keurig need?
A: Ideal pressure is 20–60 PSI. Below 20 PSI, the brewer may not fill properly. Above 60 PSI, internal seals can degrade. Use a pressure gauge and regulator if unsure.
Conclusion
Installing a direct water line plumb kit on your Keurig B150 or K150 transforms it from a convenient appliance into a true workhorse—perfect for busy offices, waiting rooms, or home offices where coffee is mission-critical. With this guide, you’ve got everything you need to complete the job safely and effectively.
Not only will you save time and reduce mess, but you’ll also enjoy better-tasting coffee thanks to consistent filtration. And let’s be honest—your team will thank you every morning.
