new filter

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.
