new filter

Hi,

I posted a message a couple of weeks ago about the Fluval 404. Based
on the imput, I went ahead and got one, and now I have a follow up
question. I'm used to an Emporer 400 (hang on), where there is no
chance for water to escape, unless the filter housing cracks, and what
are the odds of that? Anyway, this being my first canister filter,
I'm concerned about a leak in the system. With the intake tube being
low in the tank where they suggest, wouldn't the tank drain if the
hoses/connections/filter failed? If my thinking is correct and the
tank would drain, are there any safeguards that can be taken? Fluval
says no, but I thought there must be some way to guard against that
situation. Thanks again for any help.
