    Hot Water Heater
    I just installed a new water heater. I wanted to replace the shut off valve for the cold water inlet, and there is a smaller tube running next to the 3/4 copper line. Can anyone tell me what the smaller tube is and what it is for? Thanks, Dan

    One more question. I wanted to put a new shut off valve there. Any concerns or things to worry about. Can I temporarily move it until the new valve is in place?

    Nothing to worry about. Unscrew the clamp, install new valve, and reinstall the clamp. No need to even loosen the copper wire itself.
