Is there a minimum flow rate through a filter DE grid, like say 1 GPM per sq.ft., to keep the DE on the grid with constant circulation? And, is the micron rating of swimming pool DE roughly 5 nominal?
Hi, Paul. I was unable to find any info regarding a minimum only the maximum flow rate for filters. Yes, the normal micron of DE filters is around 5.
How much pressure should show on the gage? Also what do you do when DE goes back in the pool?
Hi, The filter pressure will vary depending on your pool's pump size, plumbing etc. A few things can cause DE to go back to the pool, you can read our "Getting DE Powder Back in Your Pool" blog for more info.
I have a DE filter stainless steel grids 24" long. What size filter should I get to replace the old one. don't know the model#'s pool size 30,000 gals / 16'wide / 24' length. Or can I get parts for my old DE filter.
First I would need to confirm the model number of your DE Filter in order to determine the correct grid style. The information you have doesn't specifically identify your DE filter system. Generally speaking, though, you you would have 48sf size grids.
I have an old Hayward De 2400 will a new DE 2420 just line up without any plumbing modification thanks
Hi Paul, The DE2420 will replace the DE2400 with little to not modification.
Is this filter comparable with a Hayward DE3600? Equal or better?
John, the DE2420 is going to be smaller than the DE3600. The model that will be the equivalent will be the Hayward Pro Grid DE Filter 36 Sq Ft w/o Valve.
I have a 16 x 32 inground pool. can i use the Hayward DE 4820 with a 1 1/2 hp pump?
Yes the gallons per minute rating for that pump will be fine for what the filter can handle.
Wich Pro-Grid D.E. Filter I need for a 10,000 gal. swiming pool. Thank you.
Based on the approximate surface area of your swimming pool I would use a this DE2420 model but in the end it will depend on the model pump that you have. The more flow from that pump will demand a higher sq. footage filter.
how to reattach the metal belt to the filter
Frank, Once you have the lid in place, you would place the clamp around the lip for the lid and the base. Once you have the clamp in place you would slide the bolt through the other end of the clamp then use the locking nut along onto the spring fastening the locking nut onto the bolt until the clamp is tightly fasten onto the tank.
Does this come with the valve assembly as pictured, or does that need to be purchased separately? If it is not included, what is the proper PN? Thank you
The DE2420 comes WITHOUT the valve. That can be purchased sepeartly. If you would like a Push-Pull valve, that part number is 4810-44C . If you would lkie a Multi-port valve you can either go with a 1 1/2 inch valve ( SP0710XR50 ) or the 2 inch version ( SP0740DE )
How much D.E. powder does this Hayward de2420 filter use?
This model filter uses approximately 4 lbs. of D.E. when completely empty and approximately 2 lbs. after backwashing.
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.
What is the proper range for pressure setting for this pool filter? I have one 10 years old it's running at 20-25 psi.
On an ititial run, he pressure will range between 10-20 psi. It may be higher if you have hard water.
