How do I chabge the sand in my s-200 Hayward sand

200 pounds of sand make sure you use pool filter sand make sure not to get sand in pipe

sand in your pool is a sign that you may have damage inside your sand filter. it is not uncommon for laterals to break during winter months. also, as the sand wears, it becomes smaller and may pass through.
remember that the filter sand is white. if you have sand in the pool that doesnt look like filter sand, you may have a problem with a broken line back to pool. keep an eye on your water level as you will lose water with this scenario

The problem was you didn't fill the tank with water or added the gravel to fast and now the lateral assembly is broken and letting sand into the pool. You'll need to empty the tank and replace the laterals. Add gravel slowly after you fill the tank half-way with water first.

While there is a model 711 Hayward Valve assembly, the actual filter is a different model number. You might be able to find your model here...

You will need to remove multiport valve and remove all the sand with a scoop. Not alot of fun. Think about replacing sand with ZeoBrite filter medium when you put it back together

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.

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!
