Triton II sand pool filters will need to have maintenance performed weekly to keep the pump and sand filtering the pool water properly. Sand filters filter dirt particles from the water as it flows through the pump and back to the pool. When the sand gets dirty, the pressure gauge reading will rise 3 to 10 pounds per square inch (PSI) above the normal reading when the pump was put into operation.
Turn off the Triton II pool pump. Roll out the backwash hose that is attached to the waster or drain outlet.
Turn the multiport valve to backwash. If the pump has a two-position slide valve, push the down into the backwash position and twist the handle to lock in place. Start the pump.
Allow the pump to backwash for three to five minutes or until the water in the slight glass on the top runs clear. Turn off the pump.
Turn the multiport valve to rinse. Turn on the pump. Rinse the filter for 30 seconds. If the pump has the two-position slide valve, skip this step and go to step 5.
Turn off the pump. Turn the multiport valve to filter. Raise the handle up to the filter position and twist to lock in place if the pump has the two-position slide valve.
Open the Triton II manual air bleeder on the top of the pump. Start the pump. Close the manual air bleeder after water starts blowing out of the bleeder.
