I don't notice any great rush of water when this occurs and I tilt the horizontal tank back and forth to try and make sure all the water finds the opening.</P> <P> </P> <P>So I'm wondering if some kind of gunk builds up in their, maybe the way it does in refrigerator drains. Anybody experience this? Should I ream with a pipe cleaner or some such?</P> <P><BR>Alan Barnard<BR>Salem, MO<BR>Joshua 24:15<BR><BR><BR></P></BLOCKQUOTE></BODY></HTML>
