It's a much bigger deal if the water is dirty and nasty. It it's fairly clean water from the bubble counter then disconnect it from the aquarium diffusion point and open it up all the way to blow some CO2 through it quickly to try and dry it out. The minerals and gunk that can be in the water can clog up valves, solenoids, etc...
Use a nice check valve to prevent this from happening in the future.
