Ok so we have been contacted to change out a large number of sprinklers in a
high-rise hotel. Much of the building is done in steel pipe but we have just
stumbled upon at least one wing where polybutylene is present. As far as I
know, there is no approved method of repairing this pipe once it’s been broken.
I have stopped all activity in the area.
My first though was to start cutting open the wall around the sprinklers in the
wing that contains polybutylene. At least that way I can get a wrench on the RC
and greatly reduce the risk of fracture. But even a slight risk makes me very
nervous in this situation.
Has anyone come across this and how did you handle it?
