What’s the best way to change these out?
The slats do not fit well into the holders they had to be tapped into place lightly with a small hammer so of course removing them is going to be difficult…
Has anyone made a better slat holder for the water table?
Tapping them in keeps them from wobbling which I think is a good thing. Despite that, they will come out pretty easily - potentially needing just a bit of a levered lift with a screwdriver.
As you replace the slats the slots will likely open up a bit.
I removed my slats Saturday to clean the water table. i had to tap them in. They came out as a unit. When I set them on a table there was a crow bar laying on the table. The uneven surface made them fall out of the holders. I understand what you are saying but the slats lift out and are very easy to disassemble.Turn them over or for maintenance… Very well designed.
