How do I backwash my Hayward Vertical Grid DE filter?

A  Answered on 10/8/2013 by InyoPools Product Specialist Patrick P.

When the filter pressure rises 8-10 PSI over the clean starting pressure, the filter must be backwashed. Turn off the pool pump. Rotate the multiport valve to backwash position or slide the slide valve up. When the pump is turned on, the dirty DE and water will flow out to waste. Once the water runs clear, turn off the pump. With a slide valve, push the handle down and start the pump. Once the pump is primed, add the required DE. If using a multiport valve, rotate the handle to rinse. Turn on the pump and let water flow for 20-30 seconds, cleaning out the plumbing lines. Turn off the pump and rotate the valve back to filter. Turn on the pump and once primed add required DE.

Will the filter vessel clamp provided for the current DE7220 DE Pro-Grid Filters work on the older DE7220 (S/N 107573) filters. Also has the following number in block near Model Number "330M33". Can Hayward provide legacy T-bolt (5/16" 24 tpi x 5 1/2" long SS material), associated sleeve nut, spring and washers for the older style clamp?


A  Answered on 7/31/2019 by InyoPools Product Specialist Lennox H.

Hi. Yes, the Clamp Assembly Kit - DEX2421JKIT will work with the older DE7220 filter models. Unfortunately, they're unable to provide that bolt.

Hayward DE7220 ProGrid D.E. or c7030 I have 7030 its great but I noticed when I shock or add ash or any treatment it takes forever to clear up and more frequent filter cleaning and we early used the pool at all

A  Answered on 9/12/2019 by InyoPools Product Specialist Joe S.

We would advise you would need to change the filter elements inside the unit you have.
