How to Backwash an Intex Pool Pump

The Intex pool pump has sand inside that filters the tiny dirt particles out of the water as it passes through. The sand can get dirty and will need to be backwashed when the pressure gauge reads seven to 10 pounds higher than the start-up reading on the gauge, which varies from pump to pump. Some gauges will have a red zone, which means pressure is too high and alerts you to backwash the pump.

Things You'll Need

• Backwash hose

Instructions

1. Turn off the pool pump. Roll out the backwash hose and connect it to the outlet drain on the pump. The outlet is usually at the bottom of the pump and will say "Outlet" or "Waste."

2. Lift up on the multiport valve and move it to the "Backwash" position. Press down to lock it in place. Turn on the pool pump. Allow the pump to run for one minute.

3. Turn off the pool pump. Lift up on the multiport valve and move it to the "Rinse" position. Press down on the valve to lock it in place. Turn on the pump and allow it to run for 30 seconds.

4. Turn off the pool pump. Lift up on the multiport valve and turn it back to the "Filter" position. Press down on the valve to lock it in place. Turn on the pump. It will now operate on the timer as before.

Tips & Warnings

• Always turn off the pump before moving the multiport valve or you will damage the pump and valve.
