    ??? Another crazy idea ???

    Just wanted to know if anyone has tried this and did it work.
    I hate emptying the toilet every other day. It's OK on site but when wild camping it is a struggle.
    I thought about removing the cassette from the toilet and fitting a holding tank under the van (probably from CAK tanks, pardon the pun). I could then use a large diameter pipe to connect the toilet to the tank, with a one way valve :rolleyes:
    My toilet is only used for fluids so I wonder if it would be alright.
    I thought about installing a submersible pump to empty it, via a hose pipe.

    Any thought on this subject much appreciated.

    If it's only fluid ,why not do as the French do , just do it straight into the hedge. Cut out the toilet altogether(y):)

    How do you manage wild camping if your cassette is only used for fluids?
    Or are you a bear?

    We do almost the opposite. Use the cassette mostly for solids and use the great outdoors for liquids (or the sea if warm) or bars, cafes, public conveniences if we arent staying anywhere particularly "wild". In "cassette saving" mode we can last about 4 - 5 days. I also have a spare cassette and then if worst comes to worst I carry a folding shovel to dig a hole and bury the contents somewhere where it wont be a problem.

    My toilet works very well. It goes via a pipe into a 150lt tank which I can empty via a pipe or using a cassette/tank jobby (pun intended)

    I thought I could go on the French Aires once a week and drain it responsibly.

    Anyway. My question was:
    "Just wanted to know if anyone has tried this and did it work"

    Many boats have such a system, with the option of a sea discharge for when well offshore and a pump out connection fro use in marinas. Works well and no chemicals are used normally. Also many US RVs have such a system with a gravity drain into an container like a waste hog. You do need to stand upwind of them when dumping waste though. I would thing a spare cassette wold be an easier option

    If you aren't storing solids, you had best ask CAK for a yellow tank or you might get supplied the wrong thing!:)

    if you want to drain into a tank i would think connecting to a thetford would be difficult unless you left the cassete in place and drained from that if its only liquids

    I had a thought that I could drill the cassette and fit a tap which would link to an underfloor tank.
    Easy peasy.. :giggle:

    If I am in the van on my own I only have to empty it once a month, McDonalds and the woods are perfect for my waste products, It's the mrs that doesn't like the bushes.:LOL:
    She only does 20 miles per gallon (in the thetford) these days :LOL:

    I dont think i have ever stayed on a CC site.
    A couple of CC&C sites, but big all-singing and dancing sites arent our scene.

    there is a gadget that fits in the pan of a toilet that lets women have a pee then the pee can be tipped into a separate container .
    the other way is simply get her to pee in a bucket ideally one with a lid .
    think what you might have available .
