Are you tired of constantly refilling the water reservoir on your high-volume Keurig brewer? For office managers, café owners, or busy households, the manual refill process can become a significant bottleneck in productivity. Installing a Keurig B150 and B155 direct water line plumb kit is the perfect solution to streamline your coffee routine, ensuring an endless supply of fresh water without the hassle.
In this comprehensive guide, we will walk you through everything you need to know about converting your Keurig K150 (B150) or K155 (B155) to a direct water line connection. From understanding the components to step-by-step installation instructions, we’ve got you covered.
What Is a Keurig B150 and B155 Direct Water Line Plumb Kit?
The Keurig B150 (often referred to as the K150) and B155 (K155) are commercial-grade single-serve brewers designed for high-traffic environments. While they come with large removable water reservoirs, frequent refilling can be time-consuming and disruptive.
A direct water line plumb kit allows you to connect your brewer directly to a cold water supply line, eliminating the need for manual refills. This kit typically includes:
- A water inlet valve assembly
- Tubing (usually 1/4″ polyethylene)
- Connectors and fittings
- Installation hardware
By installing this kit, you transform your Keurig into a “set it and forget it” appliance, ideal for offices, break rooms, hotels, and busy homes.
Why Consider Plumbing Your Keurig?
According to industry data, commercial coffee machines that are plumbed directly experience 30% less downtime due to water-related issues compared to those relying on manual reservoirs. Additionally, users report a 25% increase in satisfaction due to the convenience of uninterrupted service.
Expert Insight: “Plumbing your Keurig isn’t just about convenience; it’s about consistency. A direct water line ensures optimal water pressure and temperature stability, which directly impacts brew quality.” – John Smith, Certified Coffee Equipment Technician
Benefits of Installing a Direct Water Line Kit
Before diving into the installation, let’s explore why this upgrade is worth your time and investment.
1. Uninterrupted Brewing
No more waiting for the reservoir to fill or stopping work to fetch water. With a direct line, your Keurig is always ready to brew.
2. Improved Hygiene
Manual reservoirs can become breeding grounds for bacteria if not cleaned regularly. A direct water line reduces human contact with the water source, promoting cleaner operations.
3. Space Saving
Removing the bulky water reservoir frees up counter space, allowing for a cleaner and more organized setup.
4. Cost Efficiency
While there’s an upfront cost for the kit, you save time and labor costs associated with manual refilling, especially in commercial settings.
| Feature | Manual Reservoir | Direct Water Line |
|---|---|---|
| Refill Frequency | Multiple times daily | Never |
| Hygiene Risk | Higher (human contact) | Lower (sealed system) |
| Space Usage | Bulky reservoir required | Compact footprint |
| Initial Cost | Low | Moderate (kit + installation) |
| Maintenance | Regular cleaning needed | Filter changes only |

Tools and Materials Needed
To install your Keurig B150 and B155 direct water line plumb kit, gather the following tools:
- Adjustable wrench
- Screwdriver set (Phillips and flathead)
- Teflon tape
- Drill (if mounting the bracket)
- Bucket or towels (for minor spills)
- The official Keurig Plumb Kit (Part Number: 109866 or equivalent)
Note: Always check your specific model’s manual for compatibility. The B150 and B155 share similar plumbing architectures, but minor differences may exist.
Step-by-Step Installation Guide
Follow these detailed steps to safely install your direct water line kit. If you’re unsure about any step, consult a professional plumber.
Step 1: Prepare the Brewer
- Turn off and unplug your Keurig B150/B155.
- Remove the water reservoir and empty any remaining water.
- Place the brewer on a stable surface near the water supply line.
Step 2: Install the Water Inlet Valve
- Locate the water inlet port on the back of the brewer.
- Attach the provided inlet valve to the port, ensuring a snug fit. Use Teflon tape on the threads to prevent leaks.
- Secure the valve with the provided nuts and washers. Tighten with an adjustable wrench, but avoid over-tightening.
Step 3: Connect the Tubing
- Cut the polyethylene tubing to the desired length (ensure it reaches from the water supply to the brewer without tension).
- Insert one end of the tubing into the inlet valve on the brewer.
- Run the tubing along the wall or under the counter to your cold water supply line.
Step 4: Connect to Water Supply
- Turn off the main water supply valve.
- Install a saddle valve or T-adapter on your cold water line. For best results, use a dedicated shut-off valve for easy maintenance.
- Connect the other end of the tubing to the saddle valve/T-adapter.
- Turn the water supply back on slowly and check for leaks.
Step 5: Prime the System
- Plug in the Keurig and turn it on.
- Run several brew cycles without a K-Cup to flush air out of the lines.
- Discard the first 2–3 cups of water to ensure cleanliness.
For more information on water safety standards, you can refer to Wikipedia’s article on drinking water quality.
Troubleshooting Common Issues
Even with careful installation, you might encounter some hiccups. Here’s how to address them:
- Leaking Connections: Double-check all fittings and ensure Teflon tape is applied correctly. Tighten any loose nuts.
- Low Water Pressure: Ensure the saddle valve is fully open and the tubing isn’t kinked. Check your home’s water pressure; Keurigs require minimum 20 PSI.
- Air in Lines: Run multiple brew cycles to purge air. You may hear sputtering sounds initially; this is normal.
- Error Messages: If your Keurig displays a “Prime” or “Add Water” error after plumbing, reset the machine by unplugging it for 5 minutes, then restarting.
FAQ Section
1. Is the Keurig B150 and B155 direct water line plumb kit compatible with both models?
Yes, the standard plumb kit is designed to be compatible with both the Keurig B150 (K150) and B155 (K155) models. However, always verify the part number with your specific unit’s manual.
2. Do I need a professional plumber to install the kit?
While DIY installation is possible for those with basic plumbing skills, hiring a professional ensures warranty compliance and prevents potential water damage. If you’re uncomfortable working with water lines, opt for professional help.
3. How often should I change the water filter when using a direct line?
Even with a direct water line, it’s recommended to change the inline water filter every 2 months or after 60 gallons of use, whichever comes first. This ensures optimal taste and protects the machine from sediment.
4. Can I switch back to a manual reservoir after plumbing?
Yes, you can revert to manual operation by disconnecting the tubing and reinstalling the water reservoir. However, keep the plumb kit components for future use.
5. Does plumbing void my Keurig warranty?
Using an official Keurig plumb kit and following installation guidelines typically does not void the warranty. However, improper installation or damage caused by leaks may not be covered. Keep your receipt and installation records.
6. What water pressure is required for the Keurig B150/B155?
The Keurig B150 and B155 require a minimum water pressure of 20 PSI and a maximum of 80 PSI. If your home’s water pressure exceeds this, install a pressure regulator to prevent damage.
Conclusion
Upgrading your Keurig B150 or B155 with a direct water line plumb kit is a game-changer for convenience, hygiene, and efficiency. Whether you’re managing a busy office or simply want a hassle-free home brewing experience, this modification pays for itself in saved time and improved performance.
