Picnic Faucet with Ball Lock Beer Line Assembly

Reference your PFBall Unit: I infuse my empty 1L Coke bottles that are filled about 5/6 full of water with [currently] 75 psi CO2 gas topped by a carbonator cap with an extension tube to the bottom of the bottle, and first, squeeze, then tighten the cap to remove the dead air space. I had not previously been using this type unit. When ready to dispense I would remove the carbonator cap-losing pressure in the process- and replace with the standard coke bottle cap. I tried a unit similar to yours just recently. When ready to dispense, I installed the unit with difficulty, and when I presses the dispensing trigger, a combination of gas and liquid flows into the gas- spitting and splashing. I would like a smooth stream of [CO2 infused] water instead. What am i doing wrong? Is my unit defective?, Is my pressure too high? Any Assistance and comments would be most welcome. Thank You

The pressure is way higher than I would recommend. That picnic faucet is restricted for a standard keg serving pressure of 15 PSI, I am sure at 75 PSI the water is just flying out.
