I did install the carbon cartridge a few days ago, and it seems to work fine. I called the manufacturer and was referred to the internet site Limeco
--the package arrived quickly, and I ordered also the 'pack manchons
' at the rather inflated price of 10 euros (which made shipping free) as well as the 'cartouche filtre
', for 48 euros. Installation was simple--most standpipes in France seem to be 10cm in diameter, as was mine, and I just cut out the recommended 21 cm a few feet above the ground, slipped on a standard 10 cm manchon
(coupling) on the lower end of the pipe, then a sliding coupling onto the upper end. Then slipped the cartridge into the lower coupling, and finally slid the upper coupling down onto the cartridge....
Formerly, especially in the humid and still weather we've been having for a few days, there was a mild but definite and unpleasant odor outside our house which has been eliminated. The cartridge is supposed to last four years. We'll see. Our septic system is (I'm pretty positive) up to recent standards since we had it installed last winter, and checked by the local Véolia technician. Though the extractor on the top of the standpipe mentioned above does extend above the roofline, it may not be quite high enough to catch the breeze, and my ladder isn't quite high enough to safely access it to add height.
