I have a problem with my pressure regulating landing valve.When i close nozzle and open landing valve, the connection will get out the its place:
But all of a sudden, in one of the fire cabinets, the air vent open and a little air comes out, then the connection stays in its place:
may you help me please.
what can i do for other fire cabinets. the air vent is installed at the top of riser.
