Hi Experts,
Seeking advise if using threadolet instead of tee reducer for the connection of 65mm hose valve to 150mm riser is permitted?
And also using of alarm test module (1 alarm test module, 1 union patente) instead of conventional aux drain(3 valves, 2 union patente, 1 sight glass)
Thank you very much
