The Pump-out Tank is used in situations where you have to pump the urine uphill of the toilet. It is commonly used in small boats where the holding tank is located above the toilet and in basement and below ground shelter installations where the urine must be discharged to a point higher than the toilet. It diverts urine out of the toilet into a larger outside container, or drain field, eliminating the need to empty a jug by hand. Add $80
Note: At this time, the pump-out tank does not come with a pumping mechanism. There are a variety of options for pumps both manually and electronically and your situation will dictate which kind of pumping mechanism will work the best.
