Before installing Droplet, it’s important to make sure your plumbing setup is compatible. This article covers the types of pipes that work with Droplet, how much space you’ll need, and the best place to install the device for reliable performance.
🧵 What Kind of Pipes Are Compatible?
Droplet works with a wide range of standard residential plumbing materials, including:
Copper (Types M & L)
PEX
CPVC (Schedule 40 & 80)
PVC (Schedule 40 & 80)
PE (Polyethylene)
ABS
Brass
Supported pipe sizes:
Most standard nominal pipe sizes between ½" to 1-¼"* (equal to outer diameter 0.625" to 1.660")
*Note: Compatibility for pipes larger than 1” nominal diameter can vary by residence. While most installations are successful, some unique plumbing conditions may require technical support to calibrate by our support team, or in rare cases, may not be compatible.

📏 How Much Space Is Required?
For the ultrasonic sensors to function properly, Droplet needs:
Ideally have ~4 inches of straight, clean pipe on either side of the device. (The device requires a minimum of 3.5" space to fit, see the overall device dimensions here.)
A location that’s free from nearby 90° bends, splits, or tees.
A smooth pipe surface (sanding off paint or debris helps).
Droplet can still work in tighter spaces that do not have 4" of space on either side, but placing it too close to a bend, split, or tee can cause turbulence that may reduce accuracy. Always install on the straightest, cleanest section of pipe available.
To troubleshoot accuracy issues, ensure that the device is tightly clamped around the pipe and properly aligned according to the installation guidelines. Reviewing the pipe diameter and placement can resolve common performance problems. Additionally, avoid placing the Droplet after a branch or split if you need to capture water usage from all downstream lines, such as exterior faucets, to ensure accurate monitoring.
📍 Where’s the Best Place to Install Droplet?
The ideal installation location is:
On your main water line
Before any split to outdoor lines, water heaters, or irrigation systems
Near your main water shutoff valve is typically an ideal spot
In a utility area like a basement, garage, crawlspace, or utility closet. (Note: Droplet is now IP64 rated and can be installed outdoors, but please review the outdoor installation guidance here)
Before installing:
Clean the pipe surface thoroughly if there is paint, dirt, or debris
Avoid mounting over textured pipe sections, couplings, or uneven joints

Troubleshooting Common Issues
If your Droplet device isn't performing as expected:
Review Installation Setup: Verify that the device is installed according to the guidelines, particularly for pipe diameter and placement.
Check for Errors: Look out for loose clamping or improper alignment.
Submit Details to Support: Contact Hydrific Support at [email protected] with photos and descriptions of your installation to assist in diagnosing any issues. Providing detailed photos of your installation can also help expedite support responses.
Remote Calibration: Share your email associated with your Droplet account.
Install on Nearby Main Line: If your pipe has a diameter larger than the compatible range, consider installing the Droplet on a nearby section of the main line that adheres to the supported size range for proper functionality.
