Hi, hayward S-180 filter takes 150lbs, S-210 takes 200lbs not familur with the S-200. To change sand you have to remove the vari flow valve on top. You can either unplumb the filter and roll it over on its side and try washing the sand out or try scooping it out upright. Whatever you do dont damage the laterals on the bottom of the filter. When refilling with sand you want to make sure all the laterals are undamaged and in the down position. I always fill the filter half full of water to keep the sand from damaging the laterals while re-filling the filter with sand. Make sure you use pool filter sand and not play sand!

here is a link for your filter it explains how to add sand to a new filter. Im new to this too i have seen people say to use a shopvac instead of turning it on its side to prevent damage to the laterals

Take care

Sand Leaking From Filter into Pool. When my filter is running I am experiencing sand in the bottom of my pool from the filter. What can be causing that?

There is only one thing that can cause sand to come back into the pool from a sand filter. The internal assembly, called the lateral assembly, is either cracked or broken. This is an easy fix and should cost you around $70 to replace the whole thing. You need to unscrew the bottom drain cap on the filter to remove the water in the tank. Then, remove the multiport valve on top of the filter. Take a shop vac and remove the sand in the filter. If the sand hasn't been replaced in the last 3-5 years, this would be a great time to do that since you already have the sand out anyway. Then, remove the lateral assembly and inspect the entire thing. After you replace the lateral assembly, you'll need to fill the sand filter tank 1/2 full of water before adding fresh sand. This is done to cushion the laterals from the weight of the sand. Cover the hole in the top of the lateral assembly pipe with a cup or duct tape to prevent any sand from getting inside the pipe (the sand will come out into the pool if it gets into the pipe). Fill the tank 3/4 full of pool filter sand. Make sure it is genuine silica pool filter sand from a pool company. A lot of big box and home improvement stores sell play sand as filter sand. This will cause you more problems!

I have a Hayward 160T high rate sand filter. How often should the sand be changed? Can you over shock a pool when you first open it? What type of sand and where can I get it?.

Q. I have a Hayward 160T high rate sand filter. How often should the sand be changed? Every 3 - 5 years.

Q. Can you over shock a pool when you first open it? Only in the sense that a liner or some of the equipment will not like ultra-high chlorine levels and depending on the shock used you can mess up pH and Alkalinity...generally you shock with one pound per 10K gallons.

Q. What type of sand and where can I get it? #20 silica sand...some places will call it fine sand. Do not use the coarse or medium coarse sand.

Model # s244s has dirty sand and vacuum pressure is not good. Sand is dirty . Pressure valve has pressure of 50 psi

This is a serious issue. These vessels are only pressure rated to 50 PSI. Anything more can be an explosion hazard.SHUT DOWN THIS SYSTEM!

You need to remove all the sand and replace it. While your inside, you must clean the LATERALs. (small tubes on bottom of the filter)

This will reduce the pressure.

It is a good idea to replace the laterals in the bottom of this filter if it is in your budget to do so. The pvc laterals become brittle and often break when tampered with .

Note: only use #20 silica pool filter sand as a replacement.

While vacuuming my swimming pool and the valve setting is on filter, the dirty water is returning into the pool. Ive just changed a brand new spider gasket, replaced #20 silica sand. Did i miss anything...

Try changing the setting on your pool filters control valve to waste. This will bypass the filter and vacuum directly to waste. If this works, it could be a problem with the filter's "filter" setting and you may need to service or replace your control valve.

How do I put more media in my Hayward Sand Filter

To change the Media (sand, or zeolite sand replacement) you have to remove the top off the filter. There is a clamp that holds the top on. This is held together with two screws. If this is a top mount backwash valve you will have to remove the backwash valve. If you are lucky the person who installed it will have used unions so you can easily remove and replace it. If not you will have to cut pipes and re-plumb them when your done. If this is a side mount backwash valve then you should be just removing a top lid. Once you remove the top you can access the sand. You do not want to add sand without taking the old media out, and it doesn't do much good to replace only a portion of the sand. The label on the filter will tell you how much you need. Make sure you use #20 silica Pool Sand, and not any other type of sand. You can use Zeobest Zeolite sand replacement if you want a better filtration media. It cost a little more than twice the cost of sand, but you use half as much. It will filter better than cartridges, and almost as good as DE filters. You will want to "recharge" the media about once a year. this entails soaking the media in a solution overnight, then backwashing very well (another reason to use unions for the top). Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave good thumb rating if you found this helpful. Thanks, and good Luck!

How much sand does a hayward pro series sand filter require

A 24" (width of tank) is 300#
A30" is 350#
A36" is 700#
All are #20 silica and you can substute 3/8" pea gravel for up to 1/3 of sand in any of them. Rock goes in first then sand on top. This will improve your flow and extend the life of your sand.

How to refill the Hayward s200 sand filter for above ground pool

Fill the empty and cleaned tank about half way with water, cover the stand pipe in the filter with a plastic cup or some other means to ensure sand will not go down the pipe. Be sure the pipe is centered in the hole. Add 200# of #20 silica sand and once filled use your hand to reach in a level off the top as best you can. The sand will be about half way up the filter and now the water will be near or over the top. Once done, secure the valve in place and connect the hoses and you are ready to go.

How much sand do I need for a 200 series haywood filter

You should have 200 pounds of #20 Silica Sand in this filter. If you do not have enough sand, it will not filter to the best efficiency, too much and it will clog the filter.

For a copy of the Owner's Manual online, you can copy and paste the following link. Page 3 has the instructions you will need.
