You can also blow air through them.

we had same irritrol setup on our 2006 supra. disconnect bags and remove. that is all we ever did in idaho. if you feel the need, you can blow air through it but we never did. the valves will drain back down out the intake that is always open and forward into the bilge from the valves as they are typically mounted on top of the vdrive so above the drain points. hardest part was finding an incline to get all the water out of the center ski locker from that bag. always had a little left.
and that miners moss under the center bag was usually a moldy mess. we always planned a couple hours to clean out the center bag/miners moss/locker floor with a high pressure hose and some simple green. we spent most of our time ensuring engine was good. served us well for 5 years this way.
