Once you have removed the plumbing connections and the top selector plate you can then unscrew the top from the main filter body, This is not easy and you will have to use a 5 lb hammer (lumpy) and a block of wood as the top has been siliconed to the body and made a tight fit. Be very careful with the hammering and make sure you only put the wood against a solid part of the top near a plumbing joint before applying the hammer to the end of the wood. There are about 6 complete turns before the top part is unscrewed. The threads will need to be cleaned and the old silicone removed and clean the sealing gasket "o" ring before putting back. My model did not have an "fingers" at the bottom of the central stalk. I believe the filter should be filled 2/3 with the proper filter sand grade 16/30
Hope this helps

Usually in th bottom of the filter you have two parts. The first is a piece with a screen that threads into the plastic housing. The second is a Cap with a rubber washer inside. Make sure the rubber washer is there. Do not overtighten the drain into the houseing

I have sand coming out of the bottom of the davey tagelus 230 sand filter and in the pool. is this repairable with a service or should after over 25 years look at a replacement?

25 years????

That is awesome, and you absolutely got your moneys worth.

Get a new one, but if budgets are slim, as with most of us, then you can repair your filter...

Get a new drain and lateral assembly. (that is what failed)/

You will need to know the size and or model of your filter.

You will need to remove the valve if top mount; shop vac all of the sand out then rinse tank.

Install the new lateral ass\'y then...

Add new filtration media (recommend glass over sand) and reassemble any plumbing removed to access internal of tank.

Good Luck

I'm getting a little sand in the discharge during back wash

that is usually caused by damage to the fingers (laterals) on the standpipe. most times this damage comes from improper winterization or when sand is changed by non professional

Change sand in tagelus filter

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.

GASKET CHANGE: What steps should I follow to change a leaking gasket on the diverter on the valve of my DAVEY TAGELUS 230 sand filter?

make sure the valves on the outside of the pool are closed so when you open up the valve to change the gasket the pool water will not continue to run out of the filter.
Once you are secure about water flowing out of the pool through the filter you can remove the bolts holding the filter body together and change the gasket.

Can't get my pool water the right clarity no matter how much chlorine & chemical wonder if I need to change the sand in my tagelus 230

Changing the sand should do the trick. Those relatively small filters can load up with debris and oils quickly. The pump doesn't always have enough power to effectively rinse out the filter during backwash, especially if the sand is old and loaded.
One thing you may want to do is use a flocculant to drop all the suspended particles to the floor, then vacuum to waste. This will prevent all that dirt from getting into the new sand.
