Plumbing of Waste Pipe
• The outlet of the pump may be connected into the
waste pipe, e.g. former bath waste. Black rubber
fittings are provided for this.
• In confined bathrooms pump discharge may go into
the sink waste pipe using suitable adaptors.
See Fig 2.1 for McAlpine examples and their catalogue for
other variants.
Use with a Macerator Pump
• Discharge from the Whale pump must go into the
top of the macerator box. Do not use the bottom entries.
See Fig 2.2
• It is preferable to have two separate discharge lines
to waste as any failure of the macerator will not be
detected by the Whale pump.
• Avoid plumbing the pump outlet into the waste piping that
other appliances drain into as there is a risk of induced
syphoning. Use an antisyphon trap in these situations.
