I think it will be alright if you clean it regularly, and don't leave it in the water over night.. which seems like an extreme precaution but those hookahs aren't of the highest quality.
I would recommend a few different sites as well
and Hookah Johns website
But if you have a chance, I would cancel your order and see if you can find something a bit different.
Mya Saray hookahs are cheap and definitely a step up in quality, the bambino has worked great for me. (and I say that when I regularly smoke out of a nice KM)
And if you can come up with the money, Khalil Mamoon.
