    A good customer had a geothermal
    heat pump installed a couple years ago.
    I just noticed that they plumbed
    a loop to the electric water heater.
    They replaced the drain cock with a
    copper nipple when they looped in.
    Am I missing something,or isn't this
    setting up a situation for the early demise
    of the water heater?
    Looks like a brass nipple should have
    been used for this.

    Besides wanting to help out a good client,
    I just had the heater put in 3 years ago
    as part of a bath remodel I did for her
    and I'm not up for any problems for my
    warranty....especially since that plumber
    retired last year.
    TIA


    EDIT TO ADD:
    Geothermal guys are coming out next week.
    They already told the customer, over the phone
    that this dis-similar metals thing is an old wives tale,
    so some sort of citation from a recognized
    source would be nice if I'm right about this.

    Closed how?
    I think they're using the heat pump
    to pre heat for the W/H.
