A tankless unit needs a minimum flow to fire, and a trickling faucet may not trigger it. Here is the Santa Maria 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 Santa Maria Plumbing Pros will match you with a Santa Maria pro.
