Fluval issues

I have a Fluval 404 and it is to the point where I am afraid to touch it.
Everytime I break it down for maintenance it is a bugger to restart.....My
103 was a dream...never a problem.

I replaced the primer unti and when I try to prime it it still sounds like
it is sucking air. The impeller is spinning but no water is moving. ANy
ideas?

I've got two 304s, one primes OK, the other I have to pre-fill with tank
water before re-attaching. I don't know if the second one is a lemon or if
the difference in the tubing angles makes a difference. I know they will
BOTH leak if I'm not real careful putting on the tops.

I always prefill with water.....still does not help

I've got two 304s, one primes OK, the other I have to pre-fill with tank
water before re-attaching. I don't know if the second one is a lemon or if
the difference in the tubing angles makes a difference. I know they will
BOTH leak if I'm not real careful putting on the tops.

I have two 304s. I used to have problems with both of them now and again.
Since I have started doing the following I have not had any problems.

- keep a towel handy because it took me several
times to figure out exactly how high to fill the canister
and the canister often leaks until the pump is running
and the pressure builds up a little.
- use the aquastop to "lock" the water into the intake
and output tubes.
- Remove the aquastop and tubes from the top
- remove the top
- rinse all of the media, etc.
- put everything back in the canister
- put the top back on.
- prefill the canister all the way to the top where the
aquastop goes with tank water using a siphon tube
- insert the aquastop and lock it in place with the lower
lever
- open the upper lever to allow the water to flow from
the tubes
- pump the manual priming pump until water flows from
the output nozzle with each pump
- power on the pump

At this point it will usually fire up without any trouble. There will be a
lot of air because the media was uncovered while rinsing. This will usually
clear up on its own. However, I am usually impatient and will tap the side
of the canister and shake it back and forth to get the air to release more
quickly from the media.

Since the 404 is larger than the 304s I have you will have more media and
therefore you will have more trapped air. This may give you more trouble.
You can shake the canister after filling and before attaching the aquastop
to get as much of the air released as possible. You can also top off again
with water after you think you have gotten all of the air released.

Hope that helps.

I've used a lot of different Fluvals at work and at home, and it's odd
how some prime so quickly and other times, it's mission impossible. One
really bad time, I gave up after about 10 minutes, served a customer and
when I returned, it started effortlessly. The trick I use with Fluvals
or any other canister which is giving me a hard time is to remove and
lower the return hose output to below the level of the tank (or at least
below the water line), feeding into an empty pail. That usually does it
right away. You can also blow in and then power it up. This uses
gravity, so the operation of the primer is irrelevant.

For tanks where it is impractical to remove the return line - when you
are filling the tank with water (ie: from a water change), point your
water hose at the return line (doesn't work on spray bars ;~). This back
fills the return line and usually makes the restart painless. hth
