We are on septic tanks here and our cottage guests' toilet has a sign on the wall which reads:
PUT ANYTHING INTO
THE LOO UNLESS YOU
HAVE EATEN IT FIRST
Well, somebody mustn't have masticated well enough because things were less than 'flush' and I had to do some digging.
The digging is done and the flushing has flushed and all's well that ends up in the septic tank.
