SOURCE: How to change sand in Hayward S-200 Sand filter

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!

SOURCE: My new Hayward Pool Sand Filter won't backwash.

Have you ever had the top valve apart? If so, the postion of the inside diverter was not replaced correctly. Make sure the solid portion of the diverter lines up with the 'Closed" port on the valve. Once this is lined up, everything else will line back up into the correct position.

SOURCE: I can not get vacuum pressure on my Hayward Sand

The filter is most likely not the issue at all.
When you lose vacuum pressure and see bubbles the problem is usually air getting into the line killing the prime. The most common place that air gets into the line is from the strainer cover on the pump. The clear lid on the front of the pump has an o-ring that after 3 years is probably due for replacement.
With a bad o-ring it's easier for the pump to draw air through the lid then water through 20+ feet of vac hose. Replace the o-ring, make sure it is lubed well with a non petrol based grease.
The only other issue that may cause this is a cracked or seriously warped strainer lid, which should be easy to recognize once it is removed to replace the o-ring.
Once this is done you should be fine.

When to replace sand filter medium


This is sort of a two-fold answer, as I am not exactly certain if you are referring to replacing the sand filter media itself or the sand.

Most manufacturers will tell you that the sand filter media itself is a permanent media filter. The only reason to throw the filter away would be after the sand calcifies into a solid block of concrete. The industry has spent 40 years telling the professional industry that sand is forever. Sand media is forever and you never have to change it.

However... this is what Hayward Pools is telling their customers:

On average, sand should be replaced every 3-5 years. The jagged edges of the sand wear down and become smooth as the sand ages. When this happens the sand can no longer trap debris particles and dirt can pass through the sand and back into the pool. As the sand ages, it may start to clump and the water flow can form channels in the sand, allowing the debris to pass through.

I have also talked with several others who believe what Hayward is saying, that basically every 3-5 years it should be changed. We have a strong belief in what Hayward says.

Hope that helps.

Hayward pro series 220 not working. On filter mode continuously and pressure never goes up. Return pressure stays strong. water stays cloudy. I have changed sand, down pipe and now the multiport. Basi


This is not an uncommon situation for sand filters(persistent or slow to clear cloudiness). Mostly, these days , pumps are oversized for filter flow rates resulting in water being ramrodded through sand bed. The first thing to do is balance the water. If chlorine not present, double the suggested dosage. We are also assuming that the m.port valve has not been disassembled. the best sand to use is a #20 or #2 white quartzite. If problems persist , then consider filter aiding media to help the sand bed trap finer particles.

I would like to know how to 'purge' the air from S310T2 sand filter. My previous filter had a bleeder plug on the top but this one does not. Thanks!


A top mounted valve does not have an air bleeder since the air can exit thru the valve and just go thru the return line to the pool. There is no air trapped in a dome to purge.

There should be no air getting into the lines .. bleed the air out of the filter, see if there is air getting into the filter thru the pump, this will give you poor circulation . If you are loosing water , then you may have a leak in the return pipe ,, Sand is not usually orange .. but soil around the pipes may be if you are in the southwest

No suction from hayward variflow pro series sand filter


Try these tips. I am guessing that one of these is the reason that your pool filter is not working properly. If you try these suggestions and they don't work, let me know and I will trouble shoot with you again.
1. Check skimmer and pump strainer baskets for debris.
2. Check for restrictions in intake and discharge lines.
3. Check for air leak in intake line (indicated by bubbles returning to pool.
4. Backwash your filter.
5. Be sure Vari-Flo valve is set on “Filter” position.
