"With unequall pressures the higher pressure will keep closed the lower pressure valve".......maybe he must study a very little, little, little bit of hydraulics, the lower pressure hose will flow less water, so will develope exponentially lower friction loss, maintaining the valve opened and flowing....thats why in the 40.000 or so FDs, those never have had that complication.
