    Hello, hope all is well for everyone. I'm new here and my name is Steve. I'm a 3rd year Sprinkler fitter apprentice .

    I saw this the other day in a basement so please lmk what you guys think ? All help is greatly appreciated .

    Obstruction yes or no ? Sidewall sprinkler heads/line in a basement and a 4" fdc line running in front of the 1-1/2" sidewall line but lower and flush with the sidewalls. It's all exposed piping.

    Welcome

    Two ways to post

    Become a paying/ supporting member of the forum and upload pictures

    Or make the picture a link and post the link

    We would like your support and the cost is very little compared to the vast knowledge you tap into

    Just answering the four inch pipe location:

    I think though not pretty, it is ok as far as sidewall location, in relation to the four inch.


    What brand and model is the sidewall??????

    My question as an inspector is

    Is the wood above, in the last picture, fire resistive treated????


    If not than the fire sprinkler protection is wrong, because of that.

    And rethinking, would have to look at 13, but I think the sidewall is to far down from the actual ceiling.

    There may be bigger problems than the four inch question.

    This particular job the drawings don't work, it's more of a pipe and protect as you go. Since the job started the designer was in over his head and left it up to the guys in the Field. Not one part of the prints ever worked bc something or other ..

    I think most sidewall are listed for smooth ceilings only!!!!

    Which without 13, can not define, but I do not think that building basement qualifies


    May say something like """""""""""a continuous ceiling free from significant irregularities. lumps, and indentations"""""""""""""

    I am thinking as an ahj, I would write something along the line as installation does not meet NFPA 13,

    System not approved,

    Re pipe and call for re inspection.

    Plus I would not put my name or the companies name on this install, especially when you walk into court and try to defend it, after the building burns to the ground.
