The design of the vent valve is essential to ensure that the entrapped air pockets are released.

Pneumatic valves or vacuum switches should be avoided. Instead, it is preferable to use combined pneumatic 
valves that incorporate an automatic orifice, as well as a large kinetic orifice. These valves ensure that the largest 
volumes of air are released quickly and effectively while filling the pipe.
