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.

If you have a tube full of water and there is a leak in the tube below the
tank water level, it will drain until the water level is at the same
height as the leak point. Having had a Fluval 404 for years and now an
Eheim I can say that I *never* had a leak in either. With the Fluval I had
to be very careful about seating the main O-ring but once seated, no
problems.

If you are uncomfortable with this, then a sump pump with siphon break is
probably a better choice. Or, maybe you can get reverse flow siphon breaks
to put in line on your Fluval hoses.

Hi Mark,

I'll check into the reverse flow siphon breaks. I've also been told
that you can drill a hole in the intake hose just below the water line
to break the siphon if a leak should occur and you begin to lose water
volume. Any thoughts on that? Thanks again.

Yes you can. I have rigid PVC as my sump return on the 75, and I made
*3* holes just below the water line. Murphy is a bast**d, and you
just know that the next time power goes out or whatever, there will
be a snail, stromatella, or something sitting on that single hole.
