I re-fill once to twice a season. I made up a fitting like shown above. we leave the bottle valve on all day and close it when we put the car away. You can soap test the fittings to find leaks. When re-filling from a big bottle you can immerse the small bottle in ice water, it will fill with more liquid CO2 and have more pressure, also let it sit connected for a few minutes. I have a gauge just for watching the bottle pressure while it warms up. If needed you can bleed off a little. I re-fill from a beverage bottle like used on a beer tapper. Be careful and if will work fine. There is also a siphon bottle available that has a dip tube inside that way you re-fill with liquid co2 not vapor. The beverage type work fine and are way easier to find.
