So you have a "TA" filter. Which size?
It does not matter really, otherwise I would have been able to know how much sand you you have to remove and how much to put back in.
Anyway, To change sand you have to remove the MultiPort Dial valve on top.
Then, you can either unplumb the filter and roll it over on its side and using a garden hose, start washing the sand out or use a shop vac, with keeping it upright.
Whatever you do NOT 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. Always fill the filter half full of water, at least over the laterals by a few inches, 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! And... cover the stand pipe!!! Use duct tape or some kind of covering (spout cut off a water bottle then covering the pipe). Otherwise you will get sand into the standpipe and into the laterals, then you have another problem.

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.

Here is how I do it. Open the top. Open the drain on the bottom to allow the water out. Remove the plastic water difusser on the top. With a small can, scoop out the sand. When you get to the laterals, remove them for inspection. The sand below the laterals if fine, it does not need to be removed. Put the plug back in. Replace any laterals that may be broken (probably none) Fill the filter with water to about 6 inches above the laterals ... maybe more. The water will protect the laterals from the new sand as you fill the filter. It will also help the sand to pack in around the laterals. Continue filling until you are about 3 inches below the difusser that will go on the top. Make sure you don't bury the little black hose. The purpose of the little black hose is to remove the air from the filter during operation. The hose should ultimately stick up into the inside of the top (cover). I think your filter takes about 300 # of sand. Double check with your professional pool supplier where you purchase your sand. I normally will fill the filter with water before I replace the top. You may want to put on a new "O" ring too ...

This new sand should last you at least 4 to 5 years in non commercial use. After that time, you may want to replace the top 4 inches with new sand.

Thanks for your question @ FixYa.com

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!

• For our top mount filter, you must first disconnect the pipes leading into the valve and open the drain plug on the filter. Next, remove the clamp holding the multiport valve to the tank body. Once the valve has been removed, you will be able to see the sand bed. The best way to remove the sand is to either use a portable wet/dry vacuum or just scoop it out with a small can. Once the old sand has been removed, hose out the inside of the tank to clean the filter out. Once this water is drained, replace the drain cap and fill the tank 2/3 full of water. This is to protect the lateral assembly while the new sand is added. Add the sand slowly till the laterals are fully covered, then just pour in the remaining sand. DO NOT get sand in the vertical pipe sticking up from the bottom of the filter tank. The standpipe may be covered with a paper cup to prevent sand going into the pipe.
• For a side mount tank, rotate the multi-port valve to the closed position and open the filter's drain plug. Remove the tank closure dome and expose the top diffuser. The top diffuser lifts off and the old sand can be removed. The best way to remove the sand is to either use a portable wet/dry vacuum or just scoop it out with a small can. Once the old sand has been removed, hose out the inside of the tank to clean the filter out. Once this water is drained, replace the drain cap and fill the tank 2/3 full of water. This is to protect the lateral assembly while the new sand is added. Add the sand slowly till the laterals are fully covered, then just pour in the remaining sand. DO NOT get sand in the internal piping.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Hello, 1 You need to unscrew the drain plug and screen (if it is still there!) at the base of the filter. 2 You can reclaim most of the sand by letting the filter drain through a sieve (lots of work) or use new sand. 3 Uncouple union joints or couplers that attach to filter head. 4 Remove filter head. 5 You can try pulling some sand out of the top. However, do not damage the filter fingers in the sand. 6 Use a hose to blast the sand out the bottom drain. 7 Inspect all fingers, replace if necessary. 8 After all is cleaned out, place finger mount inside filter. Cover top of mount with a cup or similar to keep the new sand out of the finger assembly. 9 Replace drain plug and screen. 10 Fill filter halfway with water. 11 Slowly pour sand in and spread evenly. 12 Remove mount cover. 13 Reinstall head, unions and couplings. 14 Prime pump and test for leaks.
Good Luck

I am not that familiar with the G series Hayward filters, but most sand filter tanks do not separate. It's a labor intensive job so think hard before trying it if you haven't before. If your backwash valve is on top of the filter, the plumbing will have to be removed. There are two ways that I have removed the sand. Scooping it out by hand or using a shop vac. Remember the sand is going to be very heavy when wet. You will need to go through the top. Some filters have a large drain plug in the bottom that "supposedly" you can drain the sand out through.I have done this once and it makes a big mess that you still need to clean up.

Be sure to buy replacement o-rings and gaskets as needed. There is also a product called a sand vac that is in essence a siphoning system.

Be careful not to damage the laterals it the bottom of the filter. When replacing the sand, I put small gravel (pea gravel) carefully under and partially around the laterals to help support them from the weight of the new sand.

When you are done, be sure to backwash the new sand to remove dirt, impurities, etc. This is a general overview. There are books online that give more detail or use a similar filter's manual...

You will have to remove the sand so you might as well buy new sand. Remove drain cap and allow to drain. Remove multi port valve from top of filter. This model should have a clamp holding the valve onto the filter. You will have to disconnect the piping from valve for removal, so if it's piped solid, cut piping, and buy PVC unions to glue back in place so you can open in the future. If it's hose, then no problem. OK so once you remove the valve, you can see inside and see the sand. Take a shop vacuum and vacuum the sand from the filter. Take your time and empty vac, before it gets too heavy. Once empty, you'll see the laterals in the bottom. They if you rinse them off with a hose, to remove sand to keep from binding. The laterals should fold up to the center. Once folded you can remove assembly. After installing new laterals, partially fill the filter with water before adding sand. Cover the down pipe so no sand can enter. Add sand gently so you don't break new laterals (water helps cushion the adding of sand) You can download a manual 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
