Removing the Pump
Remove the Pump
NOTE: The pump has no serviceable parts. It is replaced as an
assembly. Retain all parts for reuse unless otherwise directed.
Should replacement ever be necessary, perform the following steps:
Turn off the water.
Drain the tank by flushing.
Unplug the electrical cord for the toilet from the outlet.
Remove the tank cover.
Unplug the modular plug and cord from the back of the trip
button.
NOTE: The larger upper hose is the jet hose and the lower smaller
hose is the rim hose. Both hoses are attached to the pump by
clamps. The upper hose is held in place in the tank by a fitting. The
lower hose slides into a hole and is held in place by friction.
Loosen and remove the upper hose clamp by sliding the
clamping heads apart.
Pull the lower rim supply hose out of the vitreous china hole.
Remove the upper jet rim hose from the pump and remove the
pump with the lower rim hose attached.
