    on 8/16/2010 i had a tankless rinnai water heater installed by my gas company and it seems that some of the pipe connections, in and outside of the house look like they are rusting. is this suppose to happen? should i have the gas company look at it.

    thanks

    Are the things rusting black iron pipe? If so, first, that may not be the best thing for outside, and second, if it is allowed needs to be painted, or like any iron, will rust.

    The outside pipe looks like it's black with gray paint on it but rust is coming through. the inside rust looks like it's occurring at connection points (these connection don't look black) between pipes and on pipe thread.

    Is this in a humid location? maybe a little oil or paint will slow it down
