I would bet a stack that the windmill domes over. My unit is a double compressor. This is directly from Koenders "At 1 ft of depth you will get 3 10' about 2.5 etc." I replaced the 3/8" line they provide with 5/8" line. The tower sits in about 1' of water and my airline goes straight down into deeper water. As far as I know mine has never frozen up. It will make a wet spot here and there throughout the winter. I am almost positive it is struggling due to doming. We moved it closer to shore and near a boulder that sticks out of the water. Will see if that improves its' performance this year. If the pipe works then next year it'll get a pipe and we will watch yet another experiment. Oh isn't learning so much FUN!!
