KNOW BEFORE YOU GO - SERIOUSLY SANDI DUMP KNOWLEDGE IS VERY IMPORTANT
The best Sani Dump location guide I have found (they seem to be regularly updating)is www.sanidumps.com
I have found in some areas it is difficult to find a Sani Dump Station, while in other areas they are a dime a dozen and free or almost free. When a website tells you there is a Sani Dump Station at a local gas station, call ahead because most gas stations have closed their Sani Dumps.
ON THE SUBJECT OF PORTA POTTIES:
I understand that most Vans are equipped, if equipped at all, with a Porta Potty as opposed to a plumbed in toiled which most RVs have. My Porta Potty has a holding tank for flush water as well as a holding tank for black water. It has a sensor light which indicates green if there is still room and changes to red if you need to dump it.
Dos and Don'ts I have learned (the hard way or communicated by an experienced friend):
~Do keep an eye on how full your black water holding tank is;
~Do make sure the toilet bowl is closed and the lid is down while traveling;
~Don't fill the flushing water tank and you wont have to empty the black water tank as often - it will also be easier to lift in and out of your camper;
~Do use a product to break down the sewage in time for you to dump it;
~Try to put toilet paper in a sanitary disposal bag instead of flushing it - it will give you more room in the black water tank - more time between dumps (no pun intended)and keep your sensor clear to register correctly;
~Do use disposable latex gloves when dumping your sewage or if not disposable be sure to wash the gloves in bleach after each dumping;
~Do use an antibacterial/disinfectant to clean the whole toilet after dumping the sewage;
