    Hot Water tank is in finished basement level. I.m always thinking..'what if the tp valve blew'
    So i.m thinking of running it about 10' of pipe ( plus 1 elbow) or so over into the laundry tub, then if for some reason it blows off it won't flood my basement floor (carpetting etc.)
    Is there any law preventing this or is this a wise move? thanks for any reply

    I think it is okay but I'm not sure so I'm hesitant to guess.

    Oops, guess I shouldn't post when I'm tired.
    2003 UPC:
    504.6.1 Discharge. The relief valve shall discharge full size
    to a safe place of disposal such as the floor, outside the building,
    or an indirect waste receptor. The discharge pipe shall
    not have any trapped sections and shall have a visible air gap
    or air gap fitting located in the same room as the water
    heater. The outlet end of the discharge pipe shall not be
    threaded and such discharge pipe shall not have a valve or
    tee installed. Relief valve piping shall be piped --->independent
    of other equipment drains<--- or relief valve discharge piping to
    the disposal point. Such pipe shall be installed in a manner
    that --->does not cause personal injury to occupants<--- in the immediate
    area or structural damage to the building.

    You could go to a floor drain...

    It would not pass here, because the laundry sink is an appliance that could be in use by someone when the discharge occured, probably scalding them. Here it has to be piped to the exterior of the building, to a floor sink, or to a mop sink on the floor that no one would be washing their hands in it at the time.
