What to do if Star PowerFlush Optima S1202 pump will not shut off?
- S
  Savannah CurtisJul 25, 2025
  If the Star Toilets pump won't shut off, it could be due to several reasons. Debris might be under the float, in which case you should remove it. Also, the float "Off" point might be adjusted too low, so try raising the lower float stop. The pump may be air locked, so ensure the vent hole in the discharge pipe is clear. If waste material has accumulated, blocking the flow, hold the flush handle down for 15 seconds. If it still won't clear, unplug the unit, wait 30 minutes, plug it back in, and repeat. If the unit still won't turn off, it needs to be opened and the debris relocated. Another reason might be that the water level is too low, in that case you should raise the lower float stop.

Why Star Toilets pump operates but delivers little or no water?

  If the Star Toilets pump operates but delivers little or no water, check for debris around the intake and clean the area. A blockage in the discharge pipe could also be the cause; remove the pipe and flush out any debris. Make sure the vent hole in the discharge pipe is clear, since the pump may be air locked. A low or incorrect voltage can cause this issue, have a qualified electrician check the house wiring. Also, vertical lift might be too high, consider changing the discharge piping.

  If the Star Toilets pump will not start, the issue could stem from a few causes. Low voltage, a blown fuse, or an open circuit could be the problem; have a qualified electrician check the fuse and circuit. Also, check for any debris on the float switch and remove it.

What to do if Star PowerFlush Optima S1202 pump starts too soon?

  danieljonesAug 12, 2025
  If the Star Toilets pump starts too soon, it is likely that the float “ON” point is adjusted too low. Raise the float stops, and make sure the float is between the two stops.

Why is the water level excessive before Star PowerFlush Optima S1202 pump turns on?
- J
  Jennifer LopezAug 18, 2025
  If the water level is excessive before the Star Toilets pump turns on, it is likely because the float “ON” point is adjusted too high. Lower the upper float stop.
