How do they empty large sand filters?

[cj133]

I was talking with a friend today and the question was brought up, how do the remove the sand from larger filters?
The 500,600 even 900 pound sand filters often used at hotels etc, how do they dump the sand out if they need to change it or fix a lateral, or even replace the filter?


My 250 I just tipped it over, but I don't think you could do that with a 900? Especially if the sand is wet.

Don't know on the commercial end.

Use a large shop vac and some patience.

That's what my friend guessed.

I'm more upset I have to tell him he was right.

@TinFoilHat I spend most of my week dealing with things that aren't easy.

Crazy expensive now, mine cost less than $25.00. If you have a place to run the sand and a bunch of water this works great:
