To be able to shoot water a distance, the pressure must be high. One pound pressure can move water upward one-half foot. If this is a residential steam system, the steam pressure is too high. This would force water up into the radiators instead of allowing clean condensed water to run down to the boiler carrying the rust away from the radiator.
