I don't post messages usually, however, you have hit on a particular sore point in this topic at present at chez O'Connell. We have recently moved to 07 after living 15 years in Cheshire quite happily with our fosse a la GB. Never needed emptying, always had a good crust and never gave off any smells (it was in the garden some 20m from the house). Our first priority 12 months ago was to have a fosse installed in our new home. It cost us an arm and a leg as it is quite a way from the house and the land slopes so we had various falls to install. Not only is my husband disgusted with the shoddy workmanship of the installation, but we have endured the worst smells I have ever known for the past 2 months and the artisan who installed the fosse does not seem to want to return my calls and messages. I am at my whits end with the whole affair at the moment. I put all the silly sachets down the toilett as advised (never had to in Cheshire) and only ever use fosse safe chemicals for cleaning etc. I think personally that the French fosses are not up to the UK standard of brick built equivalent. Any suggestion would be greatly received, sympathy included! Obviously the thing will need to be emptied and reactivated, but within a year!! Candy in 'smelly le vitrier'
