Any sludge left in the tank after the pump out will be in the bottom inch or so of the tank, which never gets completely emptied during a pump out. If the boat sits for a while after the pump out, the water will evaporate and leave a thick sludge. Fresh water squirted into the tank from a dock hose through the pump out hose will enter at the bottom of the tank, is under a bit of pressure, and the flow rate is much higher. It should do a better job OD stirring up the sludge, though it will not clear the joker valve and lines. A few gallons squirted in should help remove the sludge, then pump the tank a second time. This will help minimize the sludge. Another good idea, if you boat has been sitting a while with an empty tank, is to put 4 or 5 gallons of dockside water in through the pump out fitting and go for a day sail. That should stir up the sludge. Then add more water and pump out at the end of your day sail. Or you could install an Lectra-San, and you might never need to pump out again.
