Tankless Minimum Flow Rate: A Dearborn Heights Guide

The threshold

Tankless units fire only when flow exceeds a minimum, usually a fraction of a gallon per minute.

The symptom

A barely-open faucet may run cold because the unit never starts.

The fix

Open the faucet further, or check for a flow restriction reducing the flow below the threshold.

The call

If hot water cuts out at low flow, a pro can check. Call 888-217-3585 and Dearborn Heights Plumber Connect will match you with a Dearborn Heights pro.
