How would you go about that?
Also, it has an automatic waterer on it, how do I turn that off? Just shut off the water spigot? The property owner guy isn't around much, so getting a hold of him to ask is kind of a tall order...
I've cleaned above ground ones before, but never one that's in the ground and I've never messed around with an automatic waterer... And I'd hate to do it wrong/break something!
