Re: Fosse Septique - its management?
We use a capful of antifreeze in the traps of the shower and sinks and in the toilet bowl after reading about it on a forum. I'm hoping in the quantities we use it will not affect the fosse too much. I don't empty the toilet bowl but always do a last flush after the water has been switched off.
So far we have been relatively lucky, but this time we lost the shower thermostatic mixer AGAIN.Even though we always take it off the wall and give it a good shake, it was split wide open. We are going to replace it with a simpler mixer which hopefully will be more resilient to low temps. I heard it went to -20!
