Roxanne, the situation you describe sounds similar to what we experienced. You could see matter intermittently flowing through the suction hose but it wasn't a steady flow. Boats in the south are particular prone to small critters like mud daubers making a nest in the vent and restricting the flow. A local marine mechanic can probably show you where that vent hose is. Remove it and blow it out with air. If it's already clear, then what Viper described is something you should investigate... and that turned out to be our problem. We have an electric overboard waste pump system connected to our holding tank and that system has a vent, too. That vent was allowing in more air than the suction system was expecting. We fixed it by installing a valve inline before the overboard discharge pump and closing the valve. Now the suction pump makes quick work of it.

Good info - ours usually emits that horrible smell with the first flush after we've been gone for the week. Maybe were aren't letting enough water flush out before we leave.
