Hole in the filter cartridge or if it only happens after you clean the cartridge could just be heavy dirt falling into the pipeing when you pull the cartridge for cleaning. There is a drain plug on your filter base that you can pull to clean out the bottom of the tank and avoide this.

When sand comes back from the filter, that means that the device inside the filter that keeps the sand in has broken. In order to replace the item, all of the sand must be removed and the tubes must be removed and new ones installed. Go to your local pool supply house with your filter information and they can show you how to remove your old units and they will sell you new ones. You only have to replace the ones that are broken.

My Hayward S240 is only catching a small portion of the dead algae. I have replaced the media, the laterals are intact, and have added a filter enhancer. The spider gasket is good. I have lots of dead...

dead algae is made up of microscopic particles. Most sand filters have trouble filtering out particles that small. I would recommend using a flocculent that will force the particles to settle to the bottom, you can then set the multiport valve to the "waste" setting and vacuum as much of the debris as possible. You can use an additive like fiberclear to help the filter clear the water up quicker.

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 .

Try consulting the owners manual for these pool filters. It will give you a lot of info in the settings that your filter needs to be on to do specific tasks. I really think that it will help you get this straightened out.

Are you using the rinse setting for a few seconds following the backwash? If not, once you finish washing, stop the pump, change the valce to rinse, then run it about 3 to 5 seconds. Shut down then switch to filter and the particles should stop coming back to the pool.

I have water dripping out of my above ground return jet. What could be the problem/solution?

If by jet you mean the port the pipe fitting threads into on the filter valve, remove the fitting, retape it with about 6 complete turns of a quality teflon tape, then coat the tape with a light coating of pipe dope to ensure the drop goes away.

If that does not relate to your problem, please clarify what you mean by jet with a picture of a sand filter.

Sand is coming out of our Hayward filter and into the pool through the side return jets. How can we fix this?

One of the lateral fingers on the inside was cracked. Once we replaced this with a new one the problem ws solved.
