The bypass valve probably pushes warm water into the cold water line, allowing hot water to be at the faucet at all times. So it's not uncommon for the cold water to be lukewarm for a little bit... but you should of course get cold water after a minute.

If you're really not getting any cold water, the bypass valve is either plumbed incorrectly or is defective, pushing hot water directly into your cold tap.

Are you sure the cold water shutoff is turned back on? Can you take a picture of your setup? Maybe there's something we can see that would help.

Thanks very much for your response! I'll take pix of the Grundfos unit on the water heater and of the valve setup at the kitchen sink. Thanks again. Any advice gratefully accepted!

Attached pix of installation

The first 2 photos are of the heat activated valve installed under the kitchen sink.

The next two photos are of the Grundfos unit installed atop my water heater in the basement.

If more or more specific pix are needed, please let me know.

See anything amiss?

Thanks,
Joe
