4.1
The outlet of the pump may be connected into
the waste stack as there are three non return
valves in the pump head to prevent odours
from passing back into the bathroom.
Put the discharge from the pump into the
waste using the black rubber fittings provided.
Do not plumb pump outlet into the waste
piping that other appliances drain into as there
is a risk of induced siphoning.
4.2
In confined bathrooms you can plumb the
pump discharge into the sink waste pipe.
McAlpine™ offer waste adaptors with 22 mm
inlets. At time of print A10V and V33T offer a
solution.
Use with a Macerator Pump
4.3
Where the situation demands, or if the pipe run
is greater than that specified for the Whale
pump (see diagram 1.4 page 6) a macerator
pump may be used.
The discharge from the Whale pump must go
into the top of the macerator box and not into
lower side entries.
Do not use
the bottom entries.
It is preferable to have two separate discharge
lines to waste and drainage when used in the
same room as a macerator pump.
Any failure of the macerator will not be
detected by the Whale pump.
