📏 How Much Space Is Required?
For the ultrasonic sensors to function properly, Droplet needs:
At least 4 inches of straight, clean pipe on either side of the device
A location that’s free from nearby 90° bends, shutoff valves, or tees
A smooth pipe surface (sanding off paint or debris helps)
Droplet may still work in tighter spaces, but placing it too close to a bend or valve can 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
As close as possible to your main shutoff valve
In a utility area like a basement, garage, crawlspace, or utility closet
Before installing:
Clean the pipe surface thoroughly
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 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.5. 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.
