Dear Sirs, please permit to formulate two questions regarding to Pressure Sensor Line for jockey Pump and Main Fire Pump.
- Is it mandatory in the standard to install the two check valve DN 15 mm (1/2") with the drilled orifice of 2 mm from factory (it is really difficult to find it in that exactly condition) or is it allowed to drill yourself? I can not find anything in the standard that indicate as mandatory this valve with orifice from factory.
- Is it possible to install the pressure gauge of the pump discharge in the same line of the pressure line?
Please I really appreciate your advise in this matter.
