Pump Operation

9.1 The Whale Gulper pump uses a single
membrane to pump the water away. On the
suction stroke water and debris are drawn in
through the inlet valve. With a chamber full of
water the pump discharges the water through
the two non-return outlet valves on the purge
stroke. The two outlet valves protect the pump
against losing prime.
9.2 The aggressive flushing keeps the pump valves
clear of debris resulting in a pump which does
not require regular maintenance.
9.3 Unlike other pumps, the Whale Gulper has the
ability to run dry without causing damage to
the pump.
9.4 An additional advantage of the three non-
return valves in the pump head, is that no
smells can be passed back from the waste
stack into the shower area.

Commissioning Checklist

10.1 Before setting up the shower and running
water through the system ensure that the
shower area and gully are completely free of
building debris.
10.2 Check the following:-
a. All push fit fittings must have the twist
lock in the locked position.
b. Ensure flow switch is unstressed.
c. Check plumbing for leaks whilst pump
is running.
d. Turn the shower on and check for
correct operation.
Note: 15 minutes after showering is finished, the pump
will switch on for a brief period in order to remove any
water that may have pooled.
