How many days will a 13 gallon tank last for 2 people before having pump
it out?


Here's the math you need to know about how long it will take to fill up
any size tank:

The average adult uses the toilet 5x/day...average flush is .6 gal. So
each person continuously aboard will put about 3 gal/day into the tank.

But if you had a Therford with a 5 gallon holding the average use per
flush is about 53 uses till full.

That would be true of any similar size portapotty, whether portable or a
permanently installed "pumpable" version. However, while 53 flushes may
SEEM like a LOT more, when you remember that two people = 10
flushes/day, it's only an average of about 5 days vs 3 with a manual
toilet if you know how to use the "dry" mode to conserve flush water.
