The cold water sandwich is that blast of cold water between hot uses on a tankless unit. Here is the Longview guide.
What it is
After the hot water stops, cold water sits in the line until the unit fires again — so the next tap runs cold briefly.
Why it happens
It is normal for tankless units and is caused by the water sitting in the pipes, not a fault.
The fix
A small recirculation system or a buffer tank reduces the effect.
The call
If it bothers you, a pro can add a recirculation line. Call 888-217-3585 and Longview, TX Plumbing Pros will match you with a Longview pro.
