ABSTRACT
Special types of sanitary appliances are required for hospital sluice rooms. The slop hopper is used for the efficient disposal of bed pan excrement and general waste. The number of appliances recommended for non-domestic premises such as offices, factories, and shops varies considerably. The valve can be set manually where precise temperature control is not a requirement, but where used to supply sanitary appliances an antiscald protection measure by automatic thermostatic control set to a maximum of 48°C will be necessary. If a horizontal waste pipe is required at low level behind kitchen fitments, it must be independently trapped and some provision must be made for the machine outlet to ventilate to atmosphere. The collar is in effect a gallery with purpose-made bosses for connection of waste pipes to the discharge stack without the problem of crossflow interference.
