    Default patching a hole in fire sprinkler system

    If its a sprinkler there should be threaded unions any way. The only weld tie ins are where the 1 1/2" head lines couples into the 4" main. Home Depot will thread them for you or HF has a kit for bout 50-60.

    in many places...On any change or repair to the fire sprinkler system... the work has to be done by a contractor approved by the insurance underwriter... then inspected and recertified... in addition many municipalities and counties require an inspection and approval by their own inspectors....

    failure to do so may entail criminal as well as civil penalties on top of nullification of ALL insurance coverage...

    a failed seal and loss of air pressure could result in an entire warehouse full of goods getting soaked.... not even considering a fire..

    HF 90 amp fluxcore???????????? kidding right??

    The very best answer is to smile politely and thank him for considering you but you needed to decline the offer...
