That placement is automatic based on the center pipe resting on the bottom of the filter tank and the valve being fully seated into the opening on top of the filter and clamped into possition. You likely have damaged laterals and need to replace that assembly in order to fix the sand issue. When refilling the tank with sand, be sure to fill it nearly half way with water before adding the sand.

When backwashing...sand discharges out backwash hose..


A little sand in backwash is not uncommon. Many packaged sand filter systems use pumps whose flow rates greatly exceed the flow capacity of the filter.(the more horsepower the better, right? - Wrong) If this occurs only during back flush the the pump is too strong or the sand level is above the beginning of the rounded top of tank. The sand level will eventually correct itself.

When I was filtering the pool the sand from the sand filter is blowing sand into the pool


That means that you have a cracked lateral in your pool filter. You will need to replace the lateral, which should stop the sand from entering your pool through the return line.

Blowing sand into the pool


If your pool filters blowing sand into the pool, it means that you have a broken or cracker lateral. You will need to have the lateral replaced and it should eliminate the problem.

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.

Usually sand blowing back into the pool is either cracked laterals, a cracked hub assembly (what the laterals screw into) or a bad spider gasket is wrong with pool filters. If you are certain that the laterals and hub are not cracked then I would try replacing the spider gasket.

Why does my hayward pro series s244s blow out sand when the filter is put on, and has little to no pressure?


This indicates that one or more of the laterals are cracked or broken. You will need to open the tank, remove all the sand, inspect the laterals(tubes that come off the center 'stand pipe'). replace any that have cracks or are broken. If you can't tell, replace them all. Fill tank back up with the right amount of sand and close it all back up.

Sand in my waste water


O-rings or gasket are replaced to stop leaks, so that wouldn't have helped you.

It could be one of two things; either the white PCV-like pipe in the filter tank is cracked OR some of the laterals at the very bottom of the tank, under the sand, has melted. A whole new underdrain assembly is usually $70.

SAND IN ABOVE GROUND POOL


First, the vacuum should easily pick up sand if the pump is working properly. The sand in pool may be coming through a cracked or broken lateral. If you changed the sand recently and did not prefill the tank with water, then this could be the reason. Plastic parts do fail eventually. Be sure that you perform the rinse cycle aftewr backwashing to settle the sand bed. Instructions on filter tank.

Sand coming out of my sand filter into the pool after changing the sand in the filter


Replace the lateral assembly. Be sure to fill the tank just under half way with water before adding the sand back in. Otherwise you risk cracking the laterals.

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!
