    Hi all
    I am not sure if this has been posted before, I couldn't see it anywhere though :Smile:, I want to post it for everyones attention as this is always a subject that crops up when two RVers meet :Rofl1:.
    This is not my work but that of a Mr Charles Bruni.
    The Geo Method of Tank Cleaning, at least one of our members will be interested in reading this and maybe will challenge for copyright :Rofl1::Rofl1::Rofl1:
    Hope that you find it as interesting as I did, and "when" we get an RV again I will be trying it out, so please can we have some feedback if anyone else tries it out too?
    Thanks

    Keith

    Interesting read Keith .. but it's at odds with the advice on this site ..

    http://www.phrannie.org/macerator.html

    Two opposite views.. which is correct ? :Doh:

    I have no idea which one is correct Jim..... There seem to be many different ideas but when I read the one I posted it was the first time I had seen that idea and as it uses no real harmful chemicals I thought I would give it a go (when we finally get our RV...)
    We have tried the "culture" method in Rocky but sometimes we had horrendous smells coming from the sink wastes, and usually when dumping I found that the grey tank stank more than the black??? I guess the article I posed works on the assumption that an RV black / grey tank is a holding tank and not a septic tank, and if you follow that line of thinking then it makes sense to keep the tanks "clean" instead of carting around a mobile septic tank?
    I believe that you have gone for the septic tank idea, what is your experience of that system? Have you tried to clean out your tanks, and if so to what level of success?
    I do not pretend to know the answer mate, I am as confused as everyone else, but after trying one method (not terribly successfully) I am willing to try the alternative approach :thumb:
    I will give it a go and let you know.........

    Hi Keith

    Now more than a year full time and I've never used any chemicals or deodorants in the tanks, there are no nasty smells (except when dumping).
    After emptying the black I give it a flush with fresh water to ensure the solids are washed out..
    When possible I prefer to 'free fall' dump rather than use the macerator which is good but doesn't give the tank a good woooshhh as it empties and I never empty unless it is full to the brim, doing otherwise you run the risk of solids drying out on the tank walls, not good .. :Rofl1:

    Hi Jim
    Now that is interesting to hear. I always prefer to take the advice of those who have personal experience.......
    I never had much issue with the black tank, I also much prefer the "free fall" method as I think it discharges much better and the fuller the better. Being weekenders I do expect to get a bit of a smell from the black tank,as it sometimes does not get dropped for several weeks, but it has always been acceptable to me ( I have dealt with worse whilst at sea :Rofl1::Rofl1:) however the grey tank is absolutely heaving. So much worse than the black....... :Eeek:
    I will probably try the Geo method on our new RV grey tank, but continue with the same method as you with the black tank, unless it is stinky, then I will try the Geo method and see what happens then :thumb:
    What a wonderful Sunday lunchtime discussion :Rofl1::Rofl1:

    Hi Keith

    I think tanks and waste pipes in constant use are less likely to give problems than those used occasionally, if you think on it, the kitchen sink at home seldom smells but after two weeks on holiday .... hmm , not very pleasant :RollEyes:

    Any news on a replacement RV .. ?

    I would agree that it is the major difference between us weekenders and you guys and it certainly makes sense mate.... I will neutralise the grey from the get go...
    Replacement is still the subject of tense negotiations, so don't want to tempt fate at the moment mate, but once we have won and concluded the deal we will let you all know :Rofl1::Rofl1:

    On a related note, and one mentioned in the Geo linn Keith provided, what sort of paper does everyone use? Ordinary household stuff or specialist stuff?

    We use Thetford aqua-roll as we used to use it in the boat.

    Keith, I prefer the free fall method also :Rofl1: trouble is we dont have a lot of choice being fulltimers who never drive anywhere in our RV :( We have had two years now in our Newmar and have maybe stupidly left all the sea cocks open so that everything goes straight down the public sewer. I realised after reading odd posts on forums that we might run into trouble with crud forming on the walls of the tank but upto now we havent had a problem with smells and have only had minor blockages which i quickly cure by stuffing a fairly high power hosepipe ( and wiggling it about) down where the sun dont shine. It seems to have done the trick so far but after reading your post I'm thinking maybe i should go the route of Calgon & tide and close the stoppers occasionally and maybe lubricate things down there. being plumbed into very high pressure mains water ( on a meter I might add :( ) we always fill the toilet bowl up before flushing to ensure that the contents has no option but to wizz out the other end. Been keeping everything crossed that we dont get trouble as the last thing I fancy is getting down and dirty to dig out a blockage. :Rofl1::Rofl1:

    We started off by using the proper expensive stuff but after a while went onto sainsburys cheaper version which because its thin seems to do the trick just as well for a lot less money.

    A cassette system in an RV?

    One of the benefits of an RV holding tank system is the fact that there is no need to traipse across a site to a dump point, daily.

    Where to start????
    I think (and I am sure that an expert will contradict me, but here is my thought anyway...) that ARVs are built with large holding tanks, usually about 50 gallons, so that they are not looking for somewhere to dump every day. Most RV tanks will last a family for several days without needing to be emptied. A cassette would need to be emptied pretty much every day to stop it filling up and I do not know of any RV owners that would swap their tank for a cassette, with all the discussions that go on, it really is not a big deal, to be honest, most of the chit chat is about "which method" to use.
    I certainly would rather experiment with methods than having to do the Thetford Walk every morning :Rofl1::Rofl1::Rofl1:
    I hope this explains it mate :Laughing:

    Small price

    Yes, buy if you have problems emptying and keeping the tanks from smelling, it would be a small price to pay!:Rofl1:
    Not as silly as it first sounded!:thumb:

    Hi
    Interesting subject!!
    We had problems with VERY BAD smell from kitchen waste tank, and toilet blocking , I think the trailer had been standing some time and tanks not "used" properly. I tried some things to cure my problems, had I seen "The Geo Method" I feel sure that my tanks would soon have been sorted. In the end I used a container of "one shot" in each of the 2 problem tanks, bit risky I know, this gave me a quick fix and cleaned out the drain pipes. Since then I have used Bio-Magic and all seems to be working OK , BUT we use as much water in the black tank as possible, we even tip dish water down the loo on occasions to prevent THE BROWN MOUND. We may use GEO METHOD over the winter to see if it helps to clean off the level sensors. After reading about putting rabbit droppings in grey tanks on another forum, I have tried that , and although I feel really stupid collecting them, they do seem to work happily with BIO MAGIC.
    We just use the cheapest loo roll we can find.
    We have not had time to use the trailer as much as we would like but are trying to get to know the routine before we fulltime!!

    Our van - being a mere dwarf compared to an RV :BigGrin: - has an easily accessible grey waste outlet pipe which I empty into a bucket when necessary and a toilet cassette which I find easy enough to take to a black waste point.

    To my way of thinking it's so much easier than having tanks which have to be dumped into a MH drain - but I happily accept that others have a different view. One of the great things about motorhomes to me is the variety, from the little Romahomes up to the 37 foot monsters like Bryan & Suzy's - something to suit everyone. :Smile:

    On the related point of paper - when we bought the van the dealer (naturally) recommended the Thetford stuff. With experience we decided that Tesco Value brand shouldn't cause any problems and have been using that since finishing the pack of the posh stuff.
