King_of_the_Road Fresh Water Tank suction (none)

The tank is a 86 or so gallon tank and when it was full the water was coming out of the vent tubes back by the axles. I don't have a tank drain. To drain the tank I have to pump the water out and switch a valve from "normal flow" to "drain tank" which dumps it out right below the water control panel which is up front behind the hitch. The tank is in the back of the trailer.
