DerekJ Posted August 24, 2009 Share Posted August 24, 2009 We've just returned from a 3 week stay at our house in the Lot. Whilst we were there we were occasionally aware of what we take to be a fosse related smell when we outside on the patio.The house is around 2 years old. The various water outlets in the house are freely draining (loos, sinks etc). "Clean" water is discharging at the fosse outlet pipe. The fosse levels all look to be correct. There are two vents coming out of the roof tiles above top window level. We regularly use the infamous Eparcyl.The house is just below a ridge and the prevailing wind blow across the roof (and the vents) in the general direction of the patio.Any ideas how we might prevent this problem. It doesn't do it all the time (and teh smell isn't that strong) but when it does it isn't great if you are eating Link to comment Share on other sites More sharing options...
Cat Posted August 24, 2009 Share Posted August 24, 2009 You could try this Derek...http://www.humm-busters.com/index.html (I have no connection with the company, etc...)They will ship to France, and I have a friend who uses them and is very pleased with the results.

maude Posted August 24, 2009 Share Posted August 24, 2009 We went off the named brand of treatment and went onto using Tarax with better results. From Super U. Maude Link to comment Share on other sites More sharing options...
Âme Posted August 24, 2009 Share Posted August 24, 2009 I'll second Cat's recommendation.I put one on each of the vent pipes and the odour problem has disappeared completely. Link to comment Share on other sites More sharing options...
DerekJ Posted August 24, 2009 Author Share Posted August 24, 2009 Thanks for the replies. Much appreciated. I guess if I use the filters I need to take off the "fancy" little ventilation covers - see photo - and push the filters into the pipe. Not sure but I presume the covers will be cemented on.[IMG]http://i39.photobucket.com/albums/e170/DerekJordan/Sandbox/fosse.jpg[/IMG]I guess there are various alternatives to Eparcyl. Worth trying some alternatives I guess. Link to comment Share on other sites More sharing options...
Dave&Olive Posted August 24, 2009 Share Posted August 24, 2009 hi ok you should get the builders back , because you are living in the roof space the vents should be above the ridge. Dave Link to comment Share on other sites More sharing options...
tinabee Posted August 26, 2009 Share Posted August 26, 2009 There are special treatments that are designed for second homes where the fosse may be unused for some time. Have a look in Point Vert, their products are generally more effective than the ones you can get in the supermarkets. Link to comment Share on other sites More sharing options...
