I think what you want is a spindown filter.

And to make your life even easier, there's a timer valve that will flush it regularly.

I'm not endorsing or not endorsing these products or the seller. Just is a suggestion.

Sounds interesting Do you mean something similar to a filter with a manual valve at the bottom which can be opened to empty out sediment, etc?

Is the timer valve you mentioned built into the filter? Or is it a separate timer valve that could be attached to the filter?

Or would it mean leaving the manual valve open, and attaching, to the manual valve, a timer valve like for watering the garden?

Great! I think I understand now how it works. The only doubt I have is whether a sediment filter may be better in this case. (Or maybe to also add a sediment filter next to the spindown?)

See 2 photos attached of 2 faucet filters.

Thanks!

Depending on the volume of sediment and your setup:

A spindown filter with appropriate size screen could be your first filter to keep the larger crud out of the storage tank.

A backwashing sediment filter can clean up the rest.

I would avoid cartridge type filters - they will clog and be a maintenance hassle.

I'm not endorsing the particular product in the link - just using it as an example.

That's an impressive looking backwash filter, but I was thinking of cheaper options. What would you think of using, for example, a basic spindown filter with a timer flushing valve added to it, and then another finer sediment filter that can trap much smaller debris/ dirt. So both these filters would have flush valves plus timer flush valves added.

What do you think?

I'm not endorsing this product, just a possible example to use as a second finer (40um) filter? I would also add a timer valve (for flushing) to the above filter.

See photo of a wc cistern, with most of the water flushed. I don't remember ever cleaning it, but if I did, it was some years ago.

Thank you
