Hi again!

First, MANY thanks to you experts for the help I've gotten in the last month. I passed my plumbing inspection for my new bathroom and kitchen!

Now, on to one more little one. I'm installing gas lines. The house was previously on oil heat and all other appliances were electric, so this is completely from scratch.

As is probably true in many places, our local codes say that the system must be "under test" when the inspector comes. It says to fill the pipes with 10psi of air, and that it must maintain the pressure for at least 15 minutes.

My question is, HOW? Is there some kind of device I've never seen that screws onto the end of a black iron pipe, but has a bicycle-pump connection for pumping air in?

Any help is greatly appreciated. I've been searching Google but so far haven't had much luck.
