1E. Check voltage at toilet
while toilet is running
. If less
than nominal voltage of toilet (12, 24, or 32), check condi
tion of batteries and wire sizes. Check terminals and wire
connections for corrosion (heat at terminals and junctions
indicates a bad or corroded connection).
1F. Reposition pump wall behind macerating teeth cast in
housing cavity. Replace if necessary.
2. Poor water flow, especially at
front of bowl (or no water flow)
2A. Toilet not level.
2A. Raise rear of toilet; check with level.
2B. Restriction in intake line.

determine which is causing problem. If
intake, replace check ball and spring. If dis
charge, be sure the vent or vented loop is
clean. If intake, there is too much pressure on
