What kind of jack is this?

Are you talking about a pool? Check the laterals in your filter. You will have to remove most of the sand to do this ... also there is a small tube in the filter that must be properly connected and the top must not be in the sand.

How to Choose the Right Swimming Pool Filter?

There is a lot of confusion about various filters, many different opinions, and several important facts to consider. The first is that a pool can be properly maintained with any of the filter systems available: Sand, Cartridge, or Diatomaceous Earth (DE). Here is a brief description of each type:

Water is pushed through a bed of filter sand and removed through a set of lateral tubes at the bottom.
The filter area of a sand filter is equal to the area of the filter itself.
For example, a 24" filter will have 3.14 square feet of filter area. Only the top 1" of sand is actually used to filter the water. The principle behind this filter is that water is pushed through the filter sand, somewhat like an espresso machine. Dirty water goes in the top and clean water exits out the bottom. As the filter sand becomes plugged with debris from the pool, the pressure increases on the filter and the water flow drops. In order to clean the filter, you just run it in reverse and dump the waste water; this is referred to as "backwashing" the filter.

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!

Water comeing out cloudy and makeing suds in pool

There could be a few things causing these problems. How old is the sand in the filter? Filter sand looses its filtering ability after 3-5 years and needs to be replaced. If the sand needs to be replaced, make sure you get actual pool filter sand. A lot of big box and home improvement stores sell play sand as filter sand. That will cause your pool to stay cloudy and never clear up. If the sand is less that 3-5 years old, you may need to clean it with a liquid filter cleaner that is poured through the skimmer. This works quite well!

Another issue causing the cloudiness and bubbles could be the type of chemicals you are using. I know that shock from big box and home improvement stores cause the water to be cloudy. Algaecides from these stores also cause foaming.

Removed all old sand from filter put new sand in but getting lots of sand in the pool

when removing the old sand, you have to be extremely careful not to break any of laterals at the bottom of the tank. Also, when you added the sand, you should have filled the tank with water at least up to the lateral assembly/hub. If you have not broken a lateral and filled the tank with water up to the laterals before adding the new sand, you could have a problem with the multiport valve. Make sure the spider gasket inside is in place and not damaged/deformed. Also make sure the spring is not broken. Those are the only problems you can have with sand returning to the pool.

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.

Water is slowly leaking into the drum even though

One or both of the water inlet solenoids is/are leaking. They are just inside the cabinet where the outside water lines connect. If you have a lot of sand coming in with your water, you might install a whole house filter to trap it. If sand is getting into the solenoid valve seats, that can cause the leaking condition. Hope this helps!

My swimming pool filter returns dirty water to the

Might you have a broken lateral in the bottom of your filter and what you are seeing is sand coming into the pool?

Do you backwash daily or more often? (You should) Do you have a multi-port vavle or other type?

Im thinking broken lateral. Sucking air in and of itself will not cause dirt to return to the pool.

Whats a lateral? There is a series of pipes in the bottom of the sand with small holes in them. These holes allow water to travel in and out depending on whether you are filtering or back washing ... but not sand. If you have sand, you have a broken pipe.

Open the filter and remove the sand into a bucket to inspect the laterals.

I hope this works for you.

Tub filling very slow. Checked both hoses and they are not stopped up. what else can I do?

Did you check the screens that cover the intake tubes where you hoses connect up to see if there is any sand or grit covering the screens? A lot of times over time there are small amounts of sand or grit that comes through the water lines and it plugs off the screens where the hoses screw on.

Occasionally washer has sand in tub after rinse cycle

wow. are you on a well or city water? This means you have sand coming in from the line. and i am very suprised that your fill valve is still working usually when sand is comeing through the line it will either still the valve open causeing water to come in all the time even when turned off or it will block the solinoid and the water will just trickle in. I wouild take the hoses off the back of the unit get a five gallon bucket and turn the water on and see what is comeing out of the line. are you in a drought and on well water? maybe it is sucking the sand from the bottom of your well?
