The plumbing in our original little house has always been a nightmare – merci Albert. The septic tank is at the same height as the bathroom, so the bathroom pipes travel horizontally or possibly even uphill….
We eventually solved the problem for the loo by installing a sanibroyeur – a macerator pump – and thank goodness, since then Chris and our friend Arnard no longer had to periodically débouche this pipe. The shower pipe has been getting progressively worse, and in preparation for August visitors, I got Joris, the lad who helps in the garden, to unblock it. Hopefully this will improve things over the summer.
In September I plan to do a complete overhaul of the bathroom, including installing a sanibroyeur which deals with the shower and basin as well as loo.
