[FONT='Verdana','sans-serif']I built two of the overflows from the sticky, hooked them together, and then ran the drain through my wall to the garage. I never stopped to think about how to clean them? I feel very stupid as they are all pvc cemented into place, so I can't take it apart without destroying it. the pipe running to the garage is not so bad, as I can cut it and place a screw on coupler on it, so I can easily attach and detach it from the overflow. Have I screwed myself?[/FONT]
