I have a 20x40 inground pool. My pump is 2 hp with 2" piping. Will the Hayward DE4820 be the right pool filter to purchase? Thank you for all your help. Your website is the best website to visit with pool questions and do-it-yourself videos. Your are the best!

A     Answered on 5/13/2017 by Patrick P.

Hi June, Thanks so much for the nice compliment! The DE4820 would work fine for your 2 HP pump but if your pocketbook can afford it I would suggest the Hayward DE6020 60 Sq. Ft. filter as it has a larger filtering capacity. The larger filter capacity means more time between cleaning your DE grids, also the larger filter puts less stress on your pump allowing for a longer life on your pump.

Hello. Would like to obtain a replacement hold down ring for the filter shell, which holds the top of the filter shell to the bottom. Can you provide me a part number for the Hayward model DE4800 Serial 330L30?

A     Answered on 11/9/2016 by Megan C.

Hello, Ken. The Clamp with Spring Assembly is an Obsolete item, it is no longer manufactured. The Hayward Pro Grid DE Filter 48 Sq Ft w/o Valve - DE4820 is the replacement filter.

?     Asked on 8/7/2016 by Ian

I currently have a mirco-clear DE6000 that just let go. Will the De4820 be a suitable replacement? My pool is a 18 by 36 rectangle. Also, is the size similar or do I need to adjust the pipes coming out of the ground?

A     Answered on 8/11/2016 by Alan M.

Hello, Based on the dimensions and assumed depth of your pool, the Hayward Pro Grid DE Filter 48 Sq Ft w/o Valve will accommodate your size pool. The valve size should be the same, but the height may be different. There is a possibility you would need to do some minor replumbing of your existing piping.

IVE POURED SOME DE DIRECTLY INTO THE POOL RATHER THAN THE SKIMER I POURED THE OTHER HALF INTO SKIMMER IS ALL OK?

A     Answered on 6/26/2016 by Alex V.

Dominic, If you brush the product towards the main drain, the filter should be able to remove it from the pool.

A     Answered on 6/30/2016 by Lennox H.

Hi Mark, The DE4820 is a direct replacement for the DE4800.You can install the two filters parallel, however, you will need to install a diverter valve where the filter tee off so that you'll be able backwash the filters separately.

Mark, The newer style clamp will not fit the older style body.

?     Asked on 6/15/2016 by Karen

We currently have a Hayward Perflex EC75A would the Pro Grid 4820 be a suitable upgrade for this size DE filter. Also I assume we will need to purchase a multiport valve as well, is this correct?

A     Answered on 6/15/2016 by Patrick P.

Hi Karen, Yes the DE4820 would be the appropriate upgrade for an EC75A and you would need this Multiport Valve I like the DE4820 Pro Grid Filter over the Perflex EC75A because when you replace the grids on the Pro Grid they are about $125 where replacing all the fingers on the Perflex can be in the neighborhood of $575

I have a de4800 and need a new top lid for it. Where can I get one. Nobody seems to carry it anymore.

A     Answered on 6/9/2016 by Lennox H.

Hi, Unfortunately, the manufacturer no longer make the Top for the DE4800 filters, so you will have to replace the entire filter. The DE4820 will be a suitable replacement.

A     Answered on 4/13/2016 by Lennox H.

Hi, If you're installing a D.E. filter for the first time you will need the following: D.E. Filter, Multiport or Slide Valve, D.E. Powder, D.E. Measuing Scoop, Backwash Hose.

?     Asked on 4/1/2016 by Rick

I have a DE4800 and understand that the 4820 is the replacement. Will my multiport valve which fits the DE4800 fit onto the 4820? Can any of my Grids from the DE-4800 be used in the 4820 (now I would have a complete spare bundle)?? What other components might be interchangeable or useable?

A     Answered on 4/1/2016 by Hector F.

Yes you can use the same multi port valve, grids, and manifold. As far as any other interchangeable parts, here is the parts diagram for the 4800 and the 4820 if you need to check into those parts.

I have an 18x36 rectangle inground 3ft to 8ft deep, I currently have a DE filter Nautilus PacFab NS36, is this a good replacement or overkill? My pump is a 1.5hp superpump with 1.5" plumbing.

A     Answered on 5/31/2015 by Hector F.

Based on the model pump and surface area of your pool, this filter is a good recommendation for your application.

?     Asked on 9/16/2014 by Guest

I am getting DE back into my pool after I backwash, do you know why?

A     Answered on 9/16/2014 by Patrick P.

The main reason is that one or more of your grids are torn and DE is passing through. Please remove all the grids and thoroughly inspect each for rips or cracks in the plastic structure. Also check the manifold ( the piece the grids fit into ) for cracks in the plastic. If there is nothing wrong with either of those, one other possibility is that the spider gasket in the multi-port valve may be torn and not sealing correctly.

How much D.E. powder does this Hayward de4820 filter use?

A     Answered on 9/15/2014 by Patrick P.

This filter model uses approximately 8 lbs. of D.E. powder when completely empty and approximately 4 lbs. of D.E. after backwashing.

How do I backwash my Hayward Vertical Grid DE filter?

A     Answered on 10/8/2013 by 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.

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

from Winter Springs, FL ()

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.

 (5 out of 5 stars)  DE Filter

from Philadlephia Pa. ()

Pros: Easy to install. piping same dimension from ground as compared to previous generation hayward DE filter allowing for easy retrofit

Cons: None

Filter easy to install and works great. Not sure why it is paired with a 1 1/2 HP pump that only has 1 1/2 connections when the filter and valve are all 2" Would think for volume all piping should be the same diameter

 (5 out of 5 stars)  Much better than old style

from Jay, ME ()

Pros: Ease of cleaning

Cons: None thus far

Had an old style DE filter and took forever to remove all the bolts so I could clean out the "junk" inside and get the filter moving again. I live in the northeast and with all the leaves and algae it gets clogged in the spring when we open and it was a pain. This new filter is soo much easier.
