Diving board loose

May 14, 2008
I didn't install it, pool builders did a couple weeks ago. We have used about 3 days, noone super huge jumped off it, nothing unusual.

The problem is, it's loose side to side. I took a look at it, not sure how to fix it or what it could be. How are these attached? Just hammer it in or ??

Any suggestions? the base seems solid, but the board itself now shifts to the right or left once you start getting on the end of it.
