Hello, I noticed today that there is water inside the compression post on my 336. Is it normal for water to get in there and if so, shouldn't it drain out the bottom? If it is not normal, how might the water be getting in there? In this case, the water level is up to within 15" of the top of the post. What may be happening is the water is collecting above the jammed counter weight for the table. I can't budge the weight up or down. I don't know how long the water has been in there, maybe all from a recent rain storm or maybe it has collected over a long perid of time. thank you, Bob Pilgrim
