Hayward is the leader in the industry when it comes to filters. There are three different types of filters, Sand, DE Filters and Cartridge. Sand filters are perhaps the oldest and even the most widely used filter for swimming pool owners. There are plenty of sand filters that you can find in your local swimming pool supply store but those filters are not as top notch as Hayward. Hayward Sand Filters use a special type of sand called # 20 Silica Sand. You may not think that sand really makes a difference but it does. This type of sand has sharper edges than other types of sand.Best Hayward Sand Filters

This sand will separate debris particles and allow the water to filtrate at a higher rate than other filters. As the clean sand lands the large particles in your pool the sand removes the debris. The sand in these filters can be cleaned by simply backwashing the filter. This is a method when the reverse water flow travels through the filter and to the waste line. By doing this on a regular basis you won’t have to change your sand too often in a season. Hayward has 4 Sand Filters that would make a great addition to your swimming pool. The Pro Series Plus, The Pro Series Side Mount, Pro Series Top Mount and the S200. Read on to see which filter would best be used in your backyard.

  1. review didn’t specify what is the pro and what is the con between top mounted and side mounted filters.

  2. I just have a quiestion my filter it’s a swim pro sandfil serial #31o30 when u take the top off the tube in the middle was craced so I replaced it with pipe the same size, can u show me how to assemble this back togeher and i also put new sand in but it dosen’t seem to be working right

    • Hi Melissa,

      The first thing you are going to have to do is to remove all of the sand from the pool filter,

      After all the sand is out of the pool filter you will be able to pull out the old stand pipe and laterals and then re add the sand,

      Let me know if you have any more questions.

  3. my hayward filter circulates properly however when I vacuum the pool any green algae circulates right back into the pool through the returns. almost as if there was no sand in the filter. any suggestions?

  4. My filter recently has a very reduced circulation back into the pool. I first noticed this when trying to vacuum the pool because
    there was little suction. Also when I’ve tried to backwash the small glass “jar” on the side of the filter doesn’t fill with water.
    Any ideas on what the problem is and what I can do?

    • Hi Denise,

      The “glass jar” you are referring to is called a “filter sight glass” and its purpose is to show you what the water looks like at the end of the hose / coming out of the backwash port.

      When the “multiport” is set on “back wash” the sight glass will fill with water and when it gets clear you usually will stop back washing.

      NOW: If your sight glass in NOT filling with water on “back wash” then you most likely have a bad “spider / multiport gasket”.

      You can either replace the gasket of the multiport body is good on the multiport or you can replace the entire multiport direction valve.

      The reason you have no more suction / power is most likely because your filter is way jammed with debris because the filter is not back washing.

      Please let me know if you have any more questions or need any additional help.

  5. I have a Haywood S200 and I need to change the sand. I have removed the clear dome on top, there is a top diffuser with a tube coming up through it. How do I remove this diffuser, what all do I need to do to get to the sand to remove it. I see I should use a shop vac, no problem, I just am afraid I will brake something.

    • Hi Becky,

      You can just pull off that diffuser but that’s actually the hard way to change the sand unless you use something called a “Venture Sand Vacuum”. Then removing the dome and “vacuuming” the sand out works well.

      The easier way is to get a screw gun and get a “socket adapt” and add a socket and remove all of the bolts around that mid point and then you will be able to lift off the top part of the filter and shovel or scoop the sand out in minutes, even into a wheel barrow. That’s what we like to do, but either way is fine.

      Let me know if you have any more questions,

  6. I need to know how much sand is required for my Hayward Preflex 340L32. I think this is the model # but I can’t be sure.

    Thank you,
    Lisa

    • Hi Lisa,

      The “Hayward Perflex filter is a DE filter NOT a sand filter. This filter requires DE media, Is that what you meant?

      Please let me know,

      Joseph

  7. No. That is the information I got from the filter itself. I know for certain that it requires sand I just don’t know how much as I am a renter of the property.

    Lisa

  8. Hi Joseph,

    Husband here. :-) Yes it is DE. I was just needing to know how much to use. I had helped the owners do this job when we first moved in. Besides quantity of the DE, I was interested in the life of the filter media (fingers), and if they are in any way delicate. If so are holes or general wear easy or hard to detect? Any help in getting this job done smoothly would be appreciated.

    Peace out,

    Steve

    • Hi Steve,

      If you have an EC40 Hayward Perflex it will take 4lbs of DE

      You can see a example of a Hayward EC40 in this video here:
      http://video.wetheadmedia.com/hayward-ec40-filter-power-flo-pump-installation

      If your filter is around that size then its 4LBS, if its a tad smaller ( I think they make a special EC30, it would take 3LBS)

      Here is some other measurements of DE for the Hayward Perflex:

      EC40AC 4LBS
      EC50AC 5LBS
      EC65A 6LBS
      EC75A 7LBS

      I have seen the EC Filter last for over 22 years.

      In fact some of the REALLY REALLY OLD EC Perflex’s had a green top from the 70’s and they are still working in peoples backyards.

      The trick is to keep the filter clean, and the PH right inside the pool.

      Let me know if you have any other questions.

  9. My Hayward S200 filter had a slow drip from the pressure guage so I tightened it. I tightened it too much becasue now I have water shooting out from just above the pressure guage. There is a small crack above where the pressure gauge screws in. Is there something that can be done to fix the crack? Can I put some kind of caulk on it? Any advice would be greatly appreciated. Thank you, Karen

    • Hi Karen

      1) Remove the gauge

      2) re-wrap the gauge with new Teflon tape

      3) Apply some silicon to the internal threads and the threads on the gauge.

      4) Screw the gauge back in hand tight PLUS 1 half turn and let set for 6 hours

      5) Turn on pump and filter 6 hours later and check for leaks (should be none)

      Let me know if you have more questions or need more help,

      Joseph

  10. I have a hayward sand filter and when i vacume the pool I can see the dirty warter coming out of the jets. Any suggetions?

  11. I have the Hayward Pro Series Plus Sand Filter, When I open the relief valve on top of the filter there is very little pressure & water coming out, when I used to open it water would shoot out. Any Ideas?

  12. Yesterday I took every thing that had a gasket on it from the pool to the pump, cleaned them and added lube, I re-started and the problem was gone. My newest problem is that I just installed a new Hayward replacement pump and can not stop a small leak at the discharge on top, I have applied plumbers tape several wraps, more each time with no luck. The directions say to apply two to three wraps, I did that it leaks, keep trying more four times now, it stll has a small leak, I know that I can not use plumbers paste, what can I use?

  13. Hello, I am researching sand filters for my small inflatable pool (18′ round 4′ high) I now use the filter that came with the pool but go through a lot of cartridges which can get expensive. Can you recommend anything, I’m going for easy and inexpensive if there is such a thing! Thanks so much, Maureen

  14. I have a hayward sand filter S244-T I changed the sand in it about 1 month ago, I was on vacation and the pressure is 30psi.

    When I bypass the filter the pressure is fine at 20 PSI, so that tells me there is not a restriction in the returns, I removed the sand in the filter and checked to see if everything is ok. Put the sand back and still have the problem. I changed the multiport valve with one that was at the house… Same problem… Can it be that both my multiport valves are bad??? dont know what else to do… the pressure gage is fine… Thanks
