For slide valves, plow backwash handle and pull the valve piston straight up to the aftermath position. Lock it into position so it doesn't slide up during performance. For multiport valves, button the handle down and rotate valve to the backwash position. Be sure the handle is pressed down all the style as yous rotate it.

Step 4: Turn the equipment off again.

Stride 5: Rotate the valve to the "Rinse" position.

Switch the pump back on for about 30 seconds to rinse the grids from the "normal" filter side. The water will flow in the aforementioned as in "Filter" mode, except the water and whatsoever remaining impurities are purged out the waste line.

Step 7: Repeat steps one-6 two more than times.

Decrease the amount of backwash time to 30 seconds, then to xv seconds. Repeating the cleaning cycle helps clear the really stubborn DE powder.

Stride 8: Turn the equipment off again.

Step ix: Rotate the valve to the "Filter" position.

Step 10: Plough equipment back on and add new DE powder.

Add DE pulverization to the filter to supercede the amount that was backwashed out. Uncover the skimmer closest to the pump and filter, and slowly pour the needed amount into the skimmer while the system is running. The powder will travel through the plumbing and finer recharge the filter.
