Whats the most efficient way to adapt a large floor pump, typically designed for inflating high-pressure bicycle tires, to inflate other items like sports balls or air mattresses, which require much lower pressures? Is it simply a matter of attaching a different valve adapter, or are there other modifications or techniques required to prevent over-pressurization and potential damage to the item being inflated? Are there any specific pump features or designs that make them more or less suitable for this type of multi-purpose use?
