Emptying the water tank
As far as emptying the forward water tank, I just fire up the engine, loosen the hose clamp on the bottom of the tank, remove the hose, and let it spill into the bilge. I keep the engine running simply to keep the batteries charged while the bilge is running. May be unprofessional <G>, but it works! If I'm winterizing, I just blow out the lines with the wet vac in reverse. Jim
