Sanitop WC Macerator Unit Saniflo macerator pumping systems enable you to add facilities almost anywhere. All you need is a water and electric power supply. They're easy, quick and economic to install and you can add a new toilet under the stairs or in a garage, basement or loft conversion, a cloakroom, shower room or bathroom - even a complete kitchen or utility room with dishwasher and washing machine. Sanitop's powerful macerator enables the addition of a WC plus a wash basin. Sanitop pumps vertically to 5m or horizontally to 100m or a lesser combination of both.
