Lavie Posted December 22, 2004 Share Posted December 22, 2004 Is there a washing powder that is safe to use with a fosse? Only all those i've looked at seem to have no mention of 'sans danger pour fosse septiques' on them. So i assume they are either no good or they are all safe! Can anyone advise?

Suninfrance Posted December 22, 2004 Share Posted December 22, 2004 I always wondered about that one too, but I'm using the Apta brand (it's cheap), and so far no problems.You can buy tablets to flush down your loo once a month with helps keep the fosse bacteria healthy. It's called WC Net - they also make toilet cleaner which you can use and not damage the fosse bacteria. There are quite a few brands. Some you need to use once a month, but there is one you can use once every six months, but I haven't found it yet.Jan Link to comment Share on other sites More sharing options...
Lavie Posted December 22, 2004 Author Share Posted December 22, 2004 I've got a packet of the 6 month stuff sitting in my house at the moment, but for the life of me can't remember its name!! (and i'm now in the UK) It's sold in Super U and LeClerc and is right next to the weekly stuff (like eparcyl)As i'm about to get a w/machine i was surprised to see that washing powder seems to be the only product that doesn't mention its suitability with fosse septiques, when every other cleaning product does!

La vieille Posted December 22, 2004 Share Posted December 22, 2004 Having had a bit of a problem with the drainage recently, I know that in our property only the waste from the loo goes through the fosse, waste from the bath and washing machine just goes into the soak away, into which the "good" water from the fosse also eventually goes. I don't know if it's the same with everyone's, but this may account for why there's nothing written on the washing powder packet. Link to comment Share on other sites More sharing options...
Dave&Olive Posted December 22, 2004 Share Posted December 22, 2004 we have a sceptic tank here in the uk just do not use bio washing powder as for :- waste from the bath and washing machine just goes into the soak away, into which the "good" water from the fosse also eventually goes water from the washing machine and bath are more toxic than the water from your loo a fact Dave Link to comment Share on other sites More sharing options...

No one has ever contradicted it. AFAIK this is the way most septic tanks work and the soap powder question is irrelevant.Liz (29) Link to comment Share on other sites More sharing options...
Lavie Posted December 23, 2004 Author Share Posted December 23, 2004 Thank you for your response. At least that explains why there is no mention of it on the washing powder packs! Link to comment Share on other sites More sharing options...
Gyn_Paul Posted December 23, 2004 Share Posted December 23, 2004 A non-bio in France? Some hope!I've had no luck looking in our local supermarkets, scrutinizing (?) the small print on the back of the washing powder/liquid/tablet boxes. As far as I can tell, all the well-known brands (including the supermarket own-label ones) contain enzymes, which in my book makes them 'bio'.We've been using them for years in France and have never had a problem with our fosse (well we have, but that was the local swimming pool people parking their lorry on top of one of the regards and breaking the concrete lid, the bits of which blocked the system!). In fact, I think contributers to this thread have rather assumed that the enzymes in the detergents would be necessarilly harmful to a fosse, maybe they're not. Any chemists out there?ANY fosse installed since (about) 2000 is supposed to be a fosse toutes eaux, i.e. it takes ALL the waste water from the house.Here's another question... I have read reports that antibiotics which pass through the body and onto the fosse can damage the bacteria there..... this sounds highly unlikely, given the relative concentrations involved... anyone reckon this is true? or just something you might read in the Daily Mail?My feeling is it's as unlikely as that old chestnut about there being "more canals in Birmingham than in Venice!"Or that "you loose a third of your body heat through your head!"paul Link to comment Share on other sites More sharing options...
