OT Water well problem.

[6PTsocket]

I have normal deep(250ft) well set up with a diaphram pressure tank with a manifold attached to the one in/out fitting on the tank. After the manifold and several feet of pipe is the Honeywell screen type flushable strainer filter. On the input to the manifold is a check valve. I was getting water hammer ONLY when the pump shut off and after reading it could be the check valve, I replaced it and the water hammer stopped for a few days. When it resumed, I took a closer look at the old valve and it was full of sand. After cleaning, it was working again. My filter is after the manifold and does not keep sand out of the tank or away from the check valve. Is it normal not to have a filter before the check valve? I was good without one for a lot of years. I guess a 25 yr old well is bringing up more sand or the screen down there is shot. What I want to know is what is the best type of upstream filter to use. I saw one that creates a centrifuge to spin out the sand , with no filter element so as not to reduce pressure. I don't even know how much of an issue that is. Any advice greatly appreciated. Thanks.

might want to have this moved to parking.
Sand means the well is on it way out
either a cave in or the casing is rotted.
Pump wont last very long pumping sand.
best to find out where the sand is coming in
and seal it up or be faced with sinking a new well.

I am not catching much more sand in my after tank filter than I ever did. I have just discovered that there are centrfugal sand separators with no flow restricting filter that are specifically made to be installed ahead of the tank. One outfit even suggests capturing some sand laden water in a jar and shaking it up. If it takes under 2-3 minutes for the sand to settle out, thir separator is supposed to be effective. It took 55 seconds. If the sand is too fine it won't spin out. Mine is really coarse iron laden sand. The sand ends up in the bottom of the separator and you just purge it manually or they have auto purging on a timer. This should reduce what gets to the after tank filter. Anybody ever used a separator like this?

Nice job. Did it work as well as you expected?
