Very easy to install. That is all there is to it. Free standing, no pipes no fans although you can have one fitted but we have found that it is fine as it is. Of course we have changed over this winter, the weather is cool and it remains to be seen if we have the same zero smell in the heat of the summer but we can always add fans if necessary.
We just took out the macerator loo, blanked off all pipes and popped that one straight down.
There is a separator so ones go into a container which gets emptied well out of the way under a distant hedge kand twos go into general rubbish after being double bagged in garden type black liners.
No more having to worry about whether the next pump out machine is working!
