Required materials

  1. Backwash hose

Step 01: Turn off the sand filter

You need to turn off the sand filter before starting backwashing. Turning off the pool filter will prevent damages to the valves of the filter.

Step 02: Set the valve to the backwash

Depress the handle of the valve and set the selector notch points to the backwash. Experts recommend the pool owners to turn the valve in the same direction to reduce the chances of uniting the spider gasket. So, you should always turn on either in the right or left direction.

Step 03: Tighten waste hose to the valve

You need to tighten the waste hose to the filter’s waste point. Kinks in the waste point can hinder backwashing entirely.

Step 04: Turn the pool pump

Now, turn on the pool pump and observe the sight glass of the sand filter. Many pool owners want to know, “How long should they turn on the pump for backwashing?” There has no exact answer to this question because different sand filters require different amounts of time. If your sand filter has a sight glass, observe it and run the pump until it becomes clear. Generally, sand filters require 2 to 3 minutes to complete backwashing.

Step 05: Rinsing the pool filter

You need to rinse the sand filter after backwashing to remove excessive dirt and contaminants. To set the filter at rinse mode, you need to depress the valve’s handle and set the notch at rinse selector. Turn off the pump at the time of placing rinse mode to avoid damages. Rinse the filter for 30-50 seconds to remove dust, debris, and other contaminants.

Step 05: Set the filter mode again

You need to turn off the pump again to set the valve mode at the regular filter mode. After placing at the normal filter mode, turn on the pump. Check the pressure gauge of the filter to ensure that the filter is running at the normal ” PSI” range.

DE filter is handy to remove tiny debris from the pool. But you need to maintain it regularly. Backwashing is a regular maintenance task to keep DE filter active. If the pressure gauge of the DE filter is higher and the water of the pool looks cloudy, you need to backwash the filter.

Required Materials

  • DE powder
  • Backwash hose.

First of all, you need to roll out waste hose at the ground and remove old DE powder from the filter.

Secondly, turn the pump off from at the circuit breaker box or at the power switch to avoid dangers. Changing the modes of operation keeping the pump on can take place accidents and damage the gasket in the valve.

Thirdly, set the Multiport valve hand handle from normal filter mode to backwash mode. To fix it correctly, depress the handle and rotate to the backwash mode.

After setting the handle and attaching the waste hose to the filter, turn the pump on again. Backwash the filter 2 to 3 minutes to strip old DE powder, contaminants, debris, and small particles from the filter’s grids. You can also observe monitor sight glass to see the water. When the water inside the “monitor sight glass” turn to sparkle clear, turn off the filter.

After rinsing the filter, rotate the MPV handle and set it to the filter mode.
