Small Drip Detected

This article includes detailed information on the:

  • Flo Smart Water Monitor and Shutoff, also known as the Flo by Moen Water Shutoff 


What does Small Drip Detected mean?

Small Drip Detected is a warning that a small drip was potentially detected during a Health Test. Receiving a Small Drip Detected alert is the most common alert type, and occurs after a Health Test is run on your home water system and Flo Smart Water Monitor and Shutoff detected that there may be a small drip (or microleak) occurring somewhere in the water system.

Flo Smart Water Monitor and Shutoff proactively tests for small drips because small drips are often an early sign of vulnerability in the home plumbing system; so identifying small drips early, and correcting vulnerabilities is an important part of proactively maintaining your home and avoiding catastrophic water failure.

Most small drips are not necessarily dangerous in nature, and are relatively easy to locate. The alert is often caused by plumbing fixtures like toilets, faucets, shower heads, pool valves, ice makers or even hose bibbs that weren’t closed well or may be using tiny amounts of water. However, small drips in your home water system may also be early signs of vulnerability which may lead to pipe bursts, so properly diagnosing the culprit of this alert is crucial to maintaining a healthy home plumbing system.

Note that Flo Smart Water Monitor and Shutoff detects even the smallest and slowest of leaks, so it’s possible that you’ll receive an alert, but not see any indication of water flow through the Control Panel in the Flo by Moen app.

What do I do about Small Drip Detected?

To find a small drip, take the following steps:

1. Look. Visually inspect your faucets, shower heads and hose bibbs for drips. Tighten the handles to make sure everything is tightly closed. Now, open your Control Panel in the Moen Smart Water app to run a Health Test. If it still detects a leak, move on to Step 2.

2. Listen. Listen to your fixtures. Can you hear running water from a toilet? Toilet flappers often wear and tear over time, and need to be replaced to ensure proper sealing. If you don’t hear anything, move to Step 3.

3. Stop. Isolate your faucets, toilets, pool valves, ice makers, and other fixtures by closing their individual water supply lines. This means closing the angle stops for each fixture, one at a time. Re-run the Health Test. If it no longer detects a small drip, it was coming from one of the fixtures you closed.  

4. Ask. If you aren’t able to identify and resolve the issue (or you just want some additional help), email Flo Support or call (844) MEET-FLO.
