Having my wing tanks made from pvc and having drains in the bottom end at the root leaves very little room for water to enter hide. I believe I can get any wing tank water out through them. The main tant is tapered so that the outlet is at the bottom even when on the ramp. My only dissadvantage is that I can only check the gascolator (mounted on firewall) when the cowl is off. As a norm I always fill the wing tanks and then pump to the header so that I can always check for water. Like I mentioned before the only time I had water was after flying in rain. That time I had the cowl of soon afterwards and got a tablespoon or so of water out of the gascolator. It hasnt happened since. I also use a funnel with a water screen in it when I fuel. It keep debris and water out.
