    If you buy a new co sensor, does it come calibrated or does it need to be calibrated?

    Brazing copper to brass

    You can also use staybright 8 for copper to brass or copper to steel.

    Only needs about 500* to flow.

    Look it up on Harris, it's stronger than 15%

    I have found that if you use bubbles before using the ultrasonic, it will mask the leak.

    122/320 seems decent to me. Going off of memory but, that's about 40* evap and 100* condensing?

    So it's probably 80* outside. Seems to hot to be running in heating.
