Question: Portable Toilets and Dump Points

Umm... the 12v vacuum pump!

The vacuum pump draws about 1.5A when running - takes approximately 15 sec to recharge the vacuum after a flush. The water pump also runs for about 5 seconds and draws around 5A (depends on model). So all up it draws just over 0.01A/hrs per flush, close enough to negligible if looking at power consumption.

Hi Kensa,
The above response is absolutely correct - the vacuum pump does require energy to create the vacuum, otherwise a vacuum toilet will not work - this article has now been edited to reflect this update.
