Our marina loos have a big sign
"Do not empty Porta-Pottis or similar in these toilets. The drains can't cope and our cleaner refuses to clear up after you.
If you need this facility arrangements can be made"
As long as you only want to empty it in office hours.....
So it appears that blockage as opposed to chemicals is what they are concerned about (I would want to use environmentally friendly chemicals if at all possible anyway). I wonder what are the arrangements that they can make for emptying PPs?
