They obviously filled it from a tap, rather than using normal pool water with chlorine or salt.
Just have to make sure no-one decides that the toilet is too far away

Are you being sarcastic? Tap water isn't pure. Even after going through a softener.
I reckon it would be set up. No one is that stupid. I hope.....
And the guy on the ladder, would you empty an entire pool to drill one tiny little hole, that will only take 30seconds, and you'll be very careful not to fall, and if you fell you would have the time to throw the tool over the edge, and then you would safely land unharmed in the water?
