My G-3 runs in about 15" of water no sweat. I haven't made a gate vlave yet. But I did do a drain line mod to it!! I'll get the camera out one of these days...or maybe right now with a cup of coffee.....be right back...
here we go. I drilled a small hole and epxoyed in a quick release fitting. Using simple and inexpensive air-line tubing i run it to a drain and I don't have to worry about emptying it. I do however still need to take the top cup and all off and clean it about once a month. And that's where the quick release is nice.
