If you remove the top of the valve you will see a spider gasket that has pulled out of place. remove this and clean and dry throughly. Add a small amount of silicone sealer to the bottom of a new one and install in groves then replace top of valve and let sit for a couple of hours. That should fix. If not you will need to replace the top half of the valve also.

If you just removed the multiport valve to do the sand change and did not take it apart, there should not be any problems. You may need to take the multiport valve apart to see that the spider gasket is in place. Also, if you did not fill the tank with water up to the level of the laterals at the bottom before adding sand, you may have broken a lateral and it's allowing sand to return to the pool. I would check the spider gasket first. Also check the spring and stem to make sure that it is actually changing positions inside.

Is it leaking at the joint between the tank and valve, between the two halves of the valve, or from the center of the valve (around the handle)? If It's either of the first two, you may need to replace the o-ring. Take it apart, and check to make sure the o-ring is in good shape, and seated properly. If the o-ring is flat, oblong, or leaving black on your hands, then you should replace it. If it is leaking around the center of the handle, then you need to replace the o-ring and/or teflon seal on the shaft of the stem assembly (the part the handle connects to. To get to this you need remove the top half the valve, then drive out the pin that holds the handle on. (make a not with direction the handle and the stem are. otherwise you can be 180 degrees of when you put it back together. Hope this helps.

SOURCE: How do I replace the
Replacement of the sand is easy but there are a couple of things you want to do first.
Make sure you have a good shop-vac, get gloves, and purchase the proper sand.
This sand filter calls for #20 silica filter sand. (this will be available online, at your pool store, or at any water treatment facility).
Here is the link for this filters manual, and for the brochure (which has good pictures)
http://www.waterco.com.au/CMS/uploads/brochures/ZZB0512_Thermoplastic.pdf
http://www.waterco.com.au/CMS/uploads/Manuals/Sand_manual_829006.pdf
The manual has step by step instructions on filling and starting the filter.
The only part it doesnt tell you about is how to empty the old filter media.
To start this:
1. turn off circulation pump
2. Bleed any pressure or vacuum from the system using the bleeder valve, or just rotate the multi-port valve.
3. Open the drain valve at the bottom of the filter if there is one (some dont have one)
4. remove the collar between the multiport valve, and the tank. (this should be 2 phillips head screws)
5.Remove the multi-port valve.
you now have access to the sand.
6. Remove sand by whatever means (either a scoop or a good shop-vac with a thick hose)
be sure to be carefull once you get 2/3 of the way down the inside of the tank. There are LATERALS down there that are most likely brittle from chlorine.
Once sand is removed check and clean the laterals at the bottom of the tank.
Clean and flush the filter body and follow the directions in the manual to fill and start-up the filter.
If this helped, please vote positively for me.

Thank you for posting your question here on Fixya.com. Since you already replaced the gasket you will need to check two others things: First, inspect the groove the new gasket is sitting in as well as the mating surface of the diffuser. Be sure none of the old gasket is still there. Thoroughly clean all surfaces as well to ensure the new gasket is fully seating in the valve. If that does not cure the leak you will need a closer inspection of the mating surfaces to find a crack. Without any pump pressure on the valve it will be tough to find. It will appear as a hair like line but once the pump is on it will open up enough to let water pass. If you find a crack you can try to use a two-part plastic approved epoxy to seal it or else you will need to replace that part. If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!
