How do I backwash my Hayward Vertical Grid DE filter?
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.

(5 out of 5 stars) DE pool filter par excellence

I recently purchased a Hayward DE-3620 filter as a replacement for a 10-yr old Hayward DE-3600, and was initially most satisfied with the ability to directly install the new unit in place of the old one without having to make any adjustments whatsoever to the interface connections with the existing vari-flow valve and external piping. Upon first use, I found welcome improvements had been made to the ease of operating the air relief valve and to the pressure gage with a simple means for indicating changes in pressure from the initial setting and when filter cleaning is required. Having just encountered a particularly heavy accumulation of oak pollen and blosom debris that indicated a need to manually clean the filter elements (rather than the more usual backwash routine) I was most impressed with Hayward's changes to the design of the clamp ring and the relative ease and speed with which the top shell and the internal filter elements could be removed. I am pleased to see that Hayward has continued to improve their already great DE filter product line.

Pros: Fully compatible Hayward has a great track record for reliabilty
Replaced same size Hayward de filter which was more than 20 years old. Parts were becoming obsolete. I didn't know how much longer I could take it apart and get it back together. The new filter fit perfectly with the existing multi port valve. Can't wait for next season.

I shopped around on the internet and the price was the best and ordering easy and delivery was timely. I ordered on a Monday morning and the de filter and valve arrived on Friday afternoon. I was also impressed with the improvements to the Hayward de filter. Installation was a breeze!!

Our pool professional recommended this brand to replace our 30 year old DE filter which is no longer manufactured. It was installed 2 days ago and is working well. We also purchased the multiport valve to go with it. Very fast delivery! Ordered on a Thurs. and delivered on the next Tues. Very happy with the price and and the service.
