OK so I just finished reading 3 pages of debate of whether to put Poo in a dumpster or not.. and very little on the actual use of water on an RV toilet.. although I tend to believe Ronnie because he has /. is using an RV toilet and would know how much water it uses vs someone just tryimg to compare it to a house toilet..
It varies, water runs as long as the foots down in an RV toilet. You can flush urine with 6oz of water, or you can stand there with the foot down for 10 seconds dumping half a gallon hoping the soiled bowl washes clean before you have to reach for a brush. Its a matter of how you use it, maintain it, and what discipline you have. But if you're the type that doesn't like to take care of dirty business head on, you're probably going to resort to higher water use. Which adds up to easily a gallon a day per person.
if the flush is "on" when pedal is pressed and off when not.. then id guess water use varies depending on whether your digestive system is "Nice" to you that day or not...
Yup.
alas then if you have a Home depot bucket or fancy ""compost"" toilet.. what is the **proper** thing to do when you are travelling.. if you have a diverter you essentially have a "trucker bomb" you have to empty someplace.. and a big Doggie-bag full of sawdust and poo or diort and poo etc.. I know if I ever decide to build an RV of some type.. im not the type to grow a garden.. so I dont have my own Compost bins at home.. what would I do? some will say put it in the trash.. others will say im going to kill children if I do so...
Use Pete Moss, never sawdust. Sawdust will take months to years to compost, Pete Moss has microbial life that goes to work on waste within minutes. A couple days to a week later, whats left has been dried and "processed" by the organisms in the moss, whats left looks like potting soil. At this juncture, dump it in a bag and throw it in the trash. It will end up in a landfill where it will be fine. The bag you put it in does more environmental damage than the pseudo-compost.
for me it seems an RV toilet would be the answer since I dump it at a dumpimng station that is designed and approved for such waste..
Dump fees can range from complimentary with a stay at a park, to $5-$10. If you have to dump every week and you're full-timing, that's $40 a month plus the diesel you burn every time you have to move your rig. If you like to stay on the move, not as big of a deal. But if you're full-timing it, you probably don't want to burn through $50 in fuel by the coercion of needing to dump black water.
Confront your intention - are you going off grid full time? Or do you just want a vacation rig that you take out for a couple or a few weeks a year? Unless you're rich, you'll become fuel conscious and a bit neurotic about when, where and why you're willing to move. Requiring a dump station could end up requiring you to budget $150 or more in a month if you find yourself many many miles from civilization, making a special trip for water & dumping as opposed to a scheduled grocery & resupply trip.
seems proper venting of any type of portable toilet is paramount since there are no traditional traps for gasses...
Yes, and that's essentially a $5 tiny fan, a $10 vent and what amounts to a vacuum hose to expel the air if you DIY your own build instead of spending $950 on the Mercedes Benz of thrones. Composting toilets keep their waste bins somewhat sealed. Typically, ambient air flows in, and any possibly odorous air flows out via help from the fan. So the air is kept separated away from the interior of the rig.
ive been inside busses where the "compost" toilet stank and I thought "damn how you live like this?"
If poorly managed, anything can stink. Thoughtful design & tech is never a supplement for responsibility.
and ive been inside busses where i was like "theres a compost toilet in here?" because i didnt know it was there...
