Specifically designed to accomodate slimline sanitaryware. The sanislim will take waste fro a WC and waste water from a wash basin, shower or bidet, pumping it away to 4 metres vertically, 40 metres horizontally or a lesser combination of both. A clearance of 315mm is required from floor level to accommodate the discharge elbow (Please note, you are only buying the macerator that is circled in the picture, not the wC or anything else pictured).
