You really need to talk to the installer. Ask these same
questions. The ones I installed, only work on heat, and the
valve on the humidifier is fine. No need to close the saddle
valve.

Yours may be installed that way, or some other way. Ask the
installer. We can't see through the computer to see how s/he
installed.

It's not even bought yet. These were planning questions.

Thanks.
