Query: Water doesn't drain well

This unit does indeed sprout seeds well if you can get the water to drain through the siphon tubes. About 50% of the time, the water will fill up in one or more of the trays will refuse to drain. Of course this causes the flooded trays to rot and prevents the lower trays from getting water. If you lift the unit about an 1/8" off the counter and let it drop back down, the water will often begin to flow, but not always. Sometimes I have to tilt the unit from one side to the other until enough pressure builds up around the siphon tube.All in all, it would work well if it drained properly.
