Sanishower is suitable only for pumping away waste water from a shower or wash basin. For hot pumped soapy waste water use a Sanivite or if it is for a commercial application Sanispeed or Sanicom. Sanivite, Sanispeed and Sanicom are specifically designed for accepting hot soapy waste water pumped from washing machines, dishwashers or other applicances.
As the function of the units is to pump waste and water away, it should not usually be necessary to dig up the floor to lay the discharge pipework. It is possible to run the pipework from low level to a higher level e.g. from a basement to ground floor level, or from 1st floor up into a roofspace and then join to a soil stack
