I have a jacuzzi pool, I believe it may be as old as thrity years... Pool & hot tub employees have commented on how great it looks & are shocked at the age.

I also have a jacuzzi sand filter... I would guess it to be around 7 years old... works well & looks almost new ( from the outside... don't know what it looks like inside it)

You didn't say what type of jacuzzi equipment specifically, so I hope my answer helped in some way
