All in all, very pleased with the Separett Villa 9001. We have 4.  Here’s some things we have found. Fan motors temperamental. Separation of liquids only partially successful when used in a commercial situation so no composting for us (can be an issue with ladies hovering – TR). Had to drill 30mm drain hole in base of toilets to aid draining of water as toilets are fixed so not possible to empty water when swilling swapping ut the container (liquid due to the shower nearby). Year 2 now and seats feel a little delicate, starting to come loose. Concealing screen mechanism looked flimsy at first but has caused no problems at all. Still think the Villa 9010 is among best on market.
