Granted this may be a non-issue but, I came across an RV web site where the owner changed his static line routing from having the "tee" part of his static line in the top center to back along the side of the fuselage as is shown in Van's static kit. He stated that he was told by a couple of people that putting the tee exactly in the middle of the two ports really screwed up the measurement of the system. I am confused as to why this would be so.
My Piper Tomahawk (I have crawled back in its fuselage before) has ports on both sides of the aft fuselage with the tee in the center top of the fuselage.
It also has not only an alternate air source valve under the panel to open in case of blockage, but it has a small plunger valve by the pilots arm rest that you can push to temporarily open the system and let any water that might have collected near the static ports to drain out. It is spring loaded and closes when you release it. It is in the lowest portion of the static system. Pushing it is part of the preflight checklist.
