Can anyone help?

Its making a bit of noise, but no water movement.

the Impellers spinning though...

This might be obvious but does it have an air bubble in it?

Dont think so, I had the hose running through the filter and Have shaken the crap out of it. any other ideas?

If its noisy its got an air lock.

Stick your lips on the outlet and suck.

they can be a pain in the but to get started sometimes

impeller stuck?

Didnt work at all :-?

Impellas spinning

what about the flow control nozzle? are they open?

yeap

all i do to prime them is blow thru the spraybar end until air comes out the pick up pipe then suck until water starts coming up the spraybar pipe. reconnect the spraybar pipe to the spray bar & away it goes.

And if that doesn't work siphon out through the outlet hose into a bucket. Mine's always started flawlessly except for two times. One I'd accidentally left one of the valves closed, the other I hadn't realized I'd drained the tank down past the inlet.

is the inlet tube on the inlet and visa versa?

is the inlet tube on the inlet and visa versa?

that wouldn't stop the flow, would just enter & exit the wrong pipes.

it would stop it if the outlet was above the water

All is setup right and Have tried everything from shaking the filter, to sucking and blowing both ends :lol:

Getting really annoyed now :evil:

Will try again in the morning :roll:

can you get a siphon going through the filter?

Yeap

what happens if you start a siphon and start the filter once the siphon has started?

Nothing :lol: It stops

the siphon stops?

Oh haha, i just confused myself, If im syphoning from tank to a bucket through the filter and i turn it on it just keeps syphoning at the same speed.

I have a cf700

when mine doesnt start i tip it on its side, so the taps are pointing down. this has not failed to make it work for me. once it starts going stand it up slowly to let the bubbles out slowly

i think you should take out the impeller and then put it back in.

done that about 5 times :lol:

I just pulled the lid off mine, i assume they are similar. there is a rubber plug in the side of the head that i dont know what it does. is yours still there?
