The piper series has a Pitot mast... The front hole is for the ram air, the hole on the bottom is the drain hole and the small pinpoint hole on the rear of the mast is the static port... there is only one drain hole and that is the one on the mast... There is an alternate static source that is located under the dash on the pilot's side. Feels like a small butterfly valve.. Otherwise, I have no idea what you are refering too.. there is no drain ability for the pilot to clear the system (so to speak) from the cockpit..
