Is this the entire filter assembly? including all parts and filters with the exception of the flow control valve? From the pictures it appears to have the cap, gauge, plug and center band. In the description it talks about the filter grid. Is that included?

A  Answered on 6/9/2019 by InyoPools Product Specialist Lennox H.

Hi, Kevin. Yes, this includes the grids. It does not include the valve.

I need a full set of de grids and a manifold and the o ring for the manifold/up spout connection for my Hayword DE2400 Z10. What are the compatibles. Thanks

A  Answered on 4/28/2019 by InyoPools Product Specialist Lennox H.

Hi, Mark. The Grid Assy., 24 sqft - DEX2420DC and Outlet Pipe O-ring - DEX2400Z5 are the parts compatible with your model filter.

I have a Hayward DE2400 maybe 25 years old. The shell is cracking and since they have discontinued making these parts Id like to replace with the DE2420. My existing Hayward SP0710XR50 Pro-Series Vari-Flo Backwash Valve Coupling is only one year old and so naturally I'd like to continue using it. Can the DE2420 be purchased without the standard slide valve assembly?

A  Answered on 9/17/2018 by InyoPools Product Specialist Lennox H.

Hi, DonP. The DE2420 filter does not come with a valve, you can use your existing SP0710XR50 valve.

Can I replace the DE cartridge without buying the Pro Grid assembly

A  Answered on 6/10/2018 by InyoPools Product Specialist Lennox H.

Hi, Robert. You can replace the grid only using the 24 Sq. Ft. Grid Pack (7 Full & 1 Partial) - FG1002PACK reusing you manifold and spreader.

I have a under ground pool size. 8 x5 m and 1.5 m deep. What filter do you think I required

A  Answered on 6/9/2018 by InyoPools Product Specialist Lennox H.

Hi, Sarath. Filter's are sized based on the flow rate of your pump. You can use Inyo's How to Size a Pool Pump for Your In-Ground Pool and How To Size a Pool Filter guides to determine what size filter you will need for your pool.

I have a pool near the beah and we get a lot of sand in the pool will a DE type filter do the trick or is another typ of system recommended

A  Answered on 6/1/2018 by InyoPools Product Specialist Lennox H.

Hi, Tom. A DE Filter will provide you with the highest quality of filtration available. I would recommend a DE or sand filter in this case.

I havea16x32 inground pool with a 1 hp pump what size DE filter do I need

A  Answered on 5/11/2017 by InyoPools Product Specialist Patrick P.

We would suggest the DE3620 36 Sq. Ft DE Filter and if your pocketbook can afford it the DE4820 48 Sq. Ft. DE Filter would be ideal. The 48 Sq. Ft. has a very large filtering capacity meaning more time between cleanings and less stress on your pump, allowing your pump to last longer.

?     Asked on 3/9/2017 by Paul

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?

A  Answered on 3/10/2017 by InyoPools Product Specialist Lennox H.

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?

A  Answered on 7/9/2016 by InyoPools Product Specialist Lennox H.

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.

A  Answered on 6/7/2016 by InyoPools Product Specialist Alan M.

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.

Hi Paul, The DE2420 will replace the DE2400 with little to not modification.

Is this filter comparable with a Hayward DE3600? Equal or better?

A  Answered on 5/17/2016 by InyoPools Product Specialist Joe S.

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?

A  Answered on 4/11/2016 by InyoPools Product Specialist Hector F.

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.

A  Answered on 9/9/2015 by InyoPools Product Specialist Hector F.

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.

?     Asked on 5/5/2015 by frank

how to reattach the metal belt to the filter

A  Answered on 5/5/2015 by InyoPools Product Specialist Lennox H.

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.

?     Asked on 4/2/2015 by

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

A  Answered on 4/2/2015 by InyoPools Product Specialist Brian M.

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?

A  Answered on 9/15/2014 by InyoPools Product Specialist Patrick P.

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?

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.

?     Asked on 8/23/2013 by Guest

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.

A  Answered on 8/23/2013 by InyoPools Product Specialist Patrick P.

On an ititial run, he pressure will range between 10-20 psi. It may be higher if you have hard water.
