The device in Post No. 16 is easier to use, and it seals the condensate pipe to the device, so there is no backflow. You just stick the rubber part into the condensate drain pipe and turn on the hose. Note that, by code, there is no garden hose connection to the laundry sink faucet, so you would need to rig up a connection adapter. In my opinion, cold water from an outside hose bibb works just as well as hot water, and there is no risk of contaminating your potable water system with a backflow into your house.
I will add that it is never a good idea to connect a hose to an inside faucet because there is no vacuum breaker to prevent backflow. That is why inside faucets do not have hose connections. Outside hose bibbs have a vacuum breaker to prevent backflow.
