Our Gaslow bottles have reached their expiry dates (one is 4 years over.) so I'm looking to replace them with the newer ones with the valves/regulators that allow the use of the Bluetooth kit.
but. the bottles are still half full. what is the safest way of emptying them as Gaslow will only accept empty bottles back.
thanks
