Why Does My Moen Flo Valve Click Every Hour With No Leak Detected
- Scheduled HealthTest runs hourly
- Pressure sensor calibration in progress
- Minor pressure fluctuation triggers test
Problem Description
Moen Flo owners sometimes hear an hourly click from the valve even though the app reports no active leak. This guide explains the scheduled HealthTest behavior, misinterpretations, and what to check if the clicking is truly unexpected.
Symptoms
- Valve clicks near the top of each hour
- No leak alert shown in app
- No water loss observed during clicks
- Clicks last less than a second each
- Event log shows HealthTest entries
- Behavior started after firmware update
Recognize these? Here's what usually causes it.
Common Causes
- Scheduled HealthTest runs hourly
- Pressure sensor calibration in progress
- Minor pressure fluctuation triggers test
- Firmware update reset test schedule
- Faulty actuator exercising mid-cycle
- App HealthTest preferences not set
Most fixes happen in the first 3 steps.
Do not wrap the valve body with insulation thick enough to block airflow. The actuator needs normal heat dissipation during daily testing.

Step-by-Step Solution
Check Event Log
Open the Moen Smart Water app and review the event log for the past 24 hours. Hourly entries labeled HealthTest or micro-pressure checks explain most clicking. Normal scheduled tests confirm Flo is healthy and actively monitoring your plumbing without leaks.
Review HealthTest Settings
Navigate to HealthTest settings and confirm the schedule. Moen runs micro-pressure tests often while learning your baseline. During the first week, hourly clicks are expected. Adjust the schedule only if you have an established baseline and still find the clicks disruptive.
Check Firmware Changes
If clicks began after a firmware update, confirm the current version and check the Moen support site for known issues. Updates can reset test cadence. Either wait for the next update or contact support about rolling back if behavior is clearly off-pattern.
Listen for Loud Mechanical Clicks
Compare click volume to what you heard during installation. Significantly louder clicks suggest an actuator exercising to free itself, which can precede failure. Capture video with timestamp and contact Moen support if clicks sound mechanical rather than electronic.
Plan and Monitor
If event log matches expected HealthTest, the click is not a problem. Document baseline. If anything looks wrong in the log, open a Moen support case with at least 48 hours of event data so support can correlate clicks to tests versus other internal triggers.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
Place the valve on a short piece of foam if click sound transmits through plumbing. Simple vibration isolation makes scheduled tests inaudible.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
