Full Pumpout Tank Instructions - It is unlikely to have a full tank, as the new tank is larger than the old one. In the event the pump tank becomes full during pump out, the pump will automatically stop pumping. The tank will need to be emptied at the Dockhouse and then the boat pump out can be resumed. Do the following:

  1. Turn off pump switch and all 3 valves.
  2. Very slowly remove the hose fitting from your boat,to allow waste to drain back into boat.
  3. Carefully move the hose to the dock while keeping Green hose end elevated above tank level and roll whole assembly to pump out area at Dockhouse.
  4. Very carefully follow step 4.d through 5.g above to empty pump out tank.
  5. Disconnect the Yellow hose from the Pump and place end in sink.
  6. Then resume pumping the boat with step 1F.

Yearly Maintenance

  1. Empty oil jar on side of tank. Remove oil jar near handles and clean. Refill this jar to 3/4 full and reinstall.
  2. Run pump on discharge mode and verify that oil drips in the sight glass about every 5 seconds. Adjust via screw near fill screw, See manual.
  3. Check level of bleach in bottle and replace if low.
